How to wire a Capacitor to Ceiling Fan



The motor may be the heart of any cooler system but it is useless without quality capacitors which keep the motor and the cooler running properly. A motor capacitor such as a start capacitor or run capacitor (including a dual run capacitor) is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field. There are two common types of motor capacitors, run capacitors and start capacitors. The units of capacitance are labeled in microfarads (µF or uF). When your cooler motor do not start easily, this is indication for a capacitor which is either dead or which has lost a lot of its capacitance. There is mainly one test that you can do to check capacitor working or not: Purchase a replacement capacitor and install it. If it starts the motor reliably every single time then you can conclude that the old capacitor was the problem and you have already fixed your water cooler. The Capacitor is the only source which gives initial power to start its motion and again and again boosting will increase the speed. But as the capacitor is not working your cooler motor will not rotate in designed speed. It is right that speed can be managed by regulator but that particular speed will not achieved if capacitor is not working properly. Why Capacitor is Important in Cooler Motor Fans and coolers use induction motors. These motors require a capacitor to run. This is known as a split-phase capacitor. Your fan's motor, by design, requires two phases of current to run. But your home mains offer one phase only. A capacitor splits this phase into two separate phases with a difference of 90 degrees. What is Capacitor A capacitor is an electrical device that stores an electrical charge. They are used on fan motors. They have two electrical ratings. The first rating is the unit's capacitance which is given in microfarads (mfd). This is a measure of the amount of charge the unit can store with a specified voltage applied. The second rating is a voltage rating which tells what supply voltage the unit is rated for. This is usually 370vac or 440vac. This is important to know because if a significantly higher voltage is applied the capacitor will prematurely fail. Testing of Capacitor: If you have analog type meter, the capacitor is checked with the meter set to measure resistance. Shut off the power, discharge the capacitor and disconnect the wires attached to it. Then with the meter on the highest resistance setting, put the leads on the capacitor terminals. The resistance reading should start at zero and go up to maximum. Replacing faulty Capacitor: After your capacitor testing has shown that you have a faulty part, the replacement procedure is simple. If you have a dual run capacitor (the capacitor has three terminals on it), then you should mark the wires and write down where they go. Then simply disconnect the wires, replace the faulty part and then reconnect the wires. If your fan or cooler motor is moving slowly then the best way to increase ceiling fan speed is to change the capacitor. The reason why cooler motor slow as they get older is because the capacitor loses its capacitance. This will lead to lesser torque and speed. You can change the capacitor and restore the rated speed of cooler motor. How to increase Airflow in Cooler or Fan 1) Check its Blade Angle : The best way to check is inspect that all blades align at same angle or not and if not then make it proper. 2) Capacitor is not Working: Replace the capacitor and see the speed of cool motor. It will definitely increase and most of time problems come with capacitor only. 3) Winding Problem: Call the electrician to check the winding of your cooler motor for speed performance. Note : 1) The maximum speed is dictated by the number of poles and the frequency of the line voltage. 2) Single phase induction motor is used in ceiling fans to get a rotating field, it requires capacitors which are not self starting. Ceiling fans and coolers both require induction motors. 3) Rotational speed is a direct function of the power frequency. If you drop the frequency, the motor will slow down. Conversely, if you raise the frequency, the motor will speed up. Consideration: 1) Even though a capacitor is an inexpensive component, installing the wrong size can have a dramatic impact on an entire system. 2) If a wrong capacitor is installed, it will cause an uneven magnetic field around the rotor. This causes the rotor to hesitate at the uneven spots, resulting in irregular rotation, especially under load. This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop and the motor to overheat.

capacitor and condenser are the same.

Single-phase motors are not self-starting. A condenser spilits the phase to one of the two windings therby the motor sees 'two-phase', which helps it to start.

Capacitor or condenser is a device that is used to store an electric charge. It is basically an arrangement of conductors. Due to its characteristics, a capacitor is widely employed in the formation of electronic circuits. Capacitor stores electrical energy directly, as an electrostatic field is created between two metal "plates". A capacitor is generally constructed using two metal plates or metal foils separated by an insulator known as a dielectric material. Any non-conducting substance can be used as a dielectric material. However, porcelain, mylar, teflon, mica, cellulose are generally preferred. A capacitor is defined by the type of dielectric and electrode material selected. It also defines the application of the capacitor. The dielectric material is the main substance that helps in storing the electrical energy.

Little Things

Luck and Labor.—Neglect of Little Things.—" It will Do! —Spending of Pennies.—The Thrifty Woman.—A Helpful Wife.—A Man's Daily Life. —The Two Workmen.—Rights and Habits.—Influence of the Wife.—A Penny a Day.—The Power of a Penny.—Roads and Railways.—Business Maxims.

"Know when to spend and when to spare,
And when to buy, and thou shalt ne'er be bare."
"He that despiseth little things shall perish by little and little."—Proverbs of Solomon.

NEGLECT of small things is the rock on which the great majority of the human race has split. Human life consists of a succession of small events, each of which is comparatively unimportant, and yet the happiness and success of every man depend upon the manner in which these small events are dealt with. Character is built up on little things-little things well and honorably transacted. The success of a man in business depends on his attention to little things. The comfort of a household is the result of small things well arranged and duly provided for. Good government can only be accomplished in the same way by well-regulated provisions for the doing of little things.

Accumulations of knowledge and experience of the most valuable kind are the result of little bits of knowledge and experience carefully treasured up. Those who learn nothing, or accumulate nothing in life, are set down as failures, because they have neglected little things. They may themselves consider that the world has gone against them; but in fact, they have been their own enemies. There has long been a popular belief in " good luck;" but, like many other popular notions, it is gradually giving way. The conviction is extending that diligence is the mother of good luck; in other words, that a man's success in life will be proportionate to his efforts, to his industry, to his attention to small things. Your negligent, shiftless, loose fellows never meet with luck; because the results of industry are denied to those who will not use the proper efforts to se-cure them.

It is not luck, but labor, that makes men. Luck, says an American writer, is ever waiting for something to turn up; Labor, with keen eye and strong will, always turns up something. Luck lies in bed, and wishes the postman would bring him news of a legacy; Labor turns out at six, and with busy pen or ringing hammer lays the foundation of a competence. Luck whines; Labor whistles. Luck relies on chance; Labor, on character. Luck slips downward to self-indulgence; Labor strides upward, and aspires to independence.

There are many little things in the household, attention to which is indispensable to health and happiness. Cleanliness consists in attention to a number of apparent trifles the scrubbing of a floor, the dusting of a. chair, the cleansing of a teacup; but the general result of the whole is an atmosphere of moral and physical well-being a condition favorable to the highest growth of human character. The kind of air which circulates, in a house may seem a small matter, for we cannot see the air, and few people know anything about it; yet if we do not provide a regular supply of pure air within our houses, we shall inevitably suffer for our neglect. A few specks of dirt may seem neither here nor there, and a closed door or window would appear to make little difference; but it may make the difference of a life destroyed by fever; and therefore the little dirt and the little bad air are really very serious matters. The whole of the household regulations are, taken by themselves, trifles, but trifles tending to an important result.

A pin is a very little thing in an article of dress, but the way in which it is put into the dress often reveals to you the character of the wearer. A shrewd fellow was once looking out for a wife, and was on a visit to a family of daughters with this object. The fair one, of whom he was partially enamored, one clay entered the room in which he was seated, with her dress partially unpinned and her hair untidy: he never went back. You may say, such a fellow was "not worth a pin;" but he was really a shrewd fellow, and afterward made a good husband. He judged of women as of mea by little things; and he was right.

A druggist advertised for an assistant, and he had applications from a score of young men. He invited them all to come to his shop at the same time, and set them each to make up a pennyworth of salts into a packet. He selected the one that did this little thing in the neatest and most expert manner. He inferred their general practical ability from their performance, of this smallest bit of business.
Neglect of little things has ruined many fortunes and marred the best of enterprises. The ship which bore home the merchant's treasure was lost because it was allowed to leave the port from which it sailed with a very little hole in the bottom. For want of a nail, the shoe of the aid-de-camp's horse was lost; for want of the shoe, the horse was lost; for want of the horse, the aid-de-camp himself was lost, for the enemy took him and killed him; and for want of the aid-de-camp's intelligence, the army of his general was lost. And all because a little nail had not been properly fixed in a horse's shoe!

“It will do!" is the common phrase of those who neglect little things. " It will do!" has blighted many a character, blasted many a fortune, sunk many a ship, burned down many a house, and irretrievably ruined thousands of hopeful projects of human good. It always means stopping short of the right thing. It is a make shift. It is a failure and defeat. Not what “will do," but what is the best possible thing to do, is the point to be aimed at! Let a man once adopt the maxim of "It will do," and he is given over to the enemy; he is on the side of incompetency and defeat; and we give him up as a hopeless subject!

M. Say, the French political economist, has related the following illustration of the neglect of little things: Once, at a farm in the country, there was a gate inclosing the cattle and poultry, which was constantly swinging open for want of a proper latch. The expenditure of a penny or two, and a few minutes time, would have made all right. It was on the swing every time a per-son went out, and not being in a state to shut readily, many of the poultry were from time to time lost. One day a fine young porker made his escape, and the whole family, with the gardener, cook, and milkmaid, turned out in quest of the fugitive. The gardener was the first to discover the pig, and, in leaping a ditch to cut off his escape, got a sprain that kept him to his bed for a fortnight. The cook, on her return to the farm-house, found the linen burned that she had hung up before the fire to dry; and the milkmaid having forgotten, in her haste, to tie up the cattle in the cow-house, one of the loose cows had broken the leg of a colt that happened to be kept in the same shed. The linen burned and the gardener's work lost were worth full five pounds, and the colt worth nearly double that money: so that here was a loss in a few minutes of a large sum, purely for want of a little latch which might have been supplied for a few half pence.

Life is full of illustrations of a similar kind. When small things are habitually neglected, ruin is not far off. It is the hand of the diligent that maketh rich; and the diligent man or woman is attentive to small things as well as great. The things may appear very little and insignificant, yet attention to them is as necessary as to matters of greater moment.
Take, for instance, the humblest of coins a penny. What is the use of that little piece of copper a solitary penny? What can it buy? Of what use is it? It is half the price of a glass of beer. It is the price of a box. of matches. It is only fit for giving to a beggar. And yet how much of human happiness depends upon the spending of the penny well!

A man may work hard, and earn high wages; but if he allows the pennies, which are the result of hard work, to slip out of his fingers some going to the beer-shop, some this way, and some that he will find that his life of hard work is little raised above a life of animal drudgery. On the other hand, if he take care of the pennies, putting some weekly into a benefit society or an insurance fund, others into a savings bank, and con-fide the rest to his wife to be carefully laid out, with a view to the comfortable maintenance and culture of his family, he will soon find that his attention to small matters will abundantly repay him, in increasing means, in comfort at home, and in a mind comparatively free from fears as to the future.

All savings are made up of little things. “Many a little makes a mickle." Many a penny makes a pound.

A penny saved is the seed of pounds saved. And pounds saved means comfort, plenty, wealth, and independence. But the penny must be earned honestly. It is said that a penny earned honestly is better than a shilling given. A Scotch proverb says, “The gear that is gifted is never sae sweet as the gear that is won." What though the penny be black? "The smith and his penny are both black." But the penny earned by the smith is an honest one.

If a man does not know how to save his pennies or his pounds, his nose will always be kept to the grind-stone. Want may come upon him any day, “like an armed man." Careful saving acts like magic: once begun it grows into a habit.. It gives a man a feeling of satisfaction, of strength, of security. The pennies he has put aside in his savings-box, or in the savings-bank, give him an assurance of comfort in sickness, or of rest in old age. The man who saves has something to weather-fend him against want; while the man who saves not has nothing between him and bitter, biting poverty.

A man may be disposed to save money, and lay it by for sickness or for other purposes; but he cannot do this unless his wife lets him, or helps him. A prudent, frugal, thrifty woman is a crown of glory to her husband. She helps him in all his good resolutions; she may by quiet and gentle encouragement, bring out his better qualities; and by her example she many implant in him noble principles, which are the seeds of the highest practical virtues.

The Rev. Mr. Owen, formerly of Bilston a good friend and adviser of working-people used to tell a story of a man who was not an economist, but was enabled to become so by the example of his wife. The man was a calico-printer at Manchester, and he was. persuaded by his wife, on their wedding-day, to allow her two half-pints of ale a day, as her share. He rather winced at the bargain, for; though a drinker himself he would have preferred a perfectly sober wife. They both worked hard; and he, poor man, was seldom out of the public-house as soon as the factory work was closed.

She had her daily pint, and he, perhaps, had his two or three quarts, and neither interfered with the other; except that, at odd times, she succeeded by dint, of one little gentle artifice or another, to win him home an hour or two earlier at night; and now and then, to spend an entire evening in his own house. They had been married a year, and on the morning of their wed-ding anniversary, the husband looked askance at her neat and comely person with some shade of remorse, as he said, " Mary, we've had no holiday since we were wed; and, only that I have not a penny in the world, we'd take a jaunt down to the village to see the mother."

“Wouldst like to go, John?" said she, softly, between a smile and a tear, so glad to hear him speak so kindly so like old times. "If thee'd like to go, John, I'll stand treat."
“Thou stand treat!" said he, with half a sneer: " hast got a fortun, wench ?"
“A Helpful Wife. 607” Nay," said she,” but I've gotten the pint o' ale."
“Gotten what?" said he.
“The pint o' ale!" said she.

John still didn't understand her, till the faithful creature reached down an old stocking from under a loose brick up the chimney, and counted out her daily pint of ale in the shape of three hundred and sixty-five three pence, i. e., four pounds four shillings and six-pence,, and put them into his hand, exclaiming, " Thou shalt have thee holiday, John!"

John was ashamed, astonished, conscience-stricken, charmed, and wouldn't touch it. “Hasn’t thee had thy share? Then I'll ha' no more!" he said. He kept his word. They kept their wedding-day with mother; and the wife's little capital was the nucleus of a series-of frugal investments, that ultimately swelled out into a shop, a factory, warehouses, a country-seat, carriage, and, perhaps, a Liverpool mayor.

In the same way, a workman of even the humblest sort, whose prosperity and regularity of conduct show to his fellow-workmen what industry, temperance, manly tenderness, and superiority to low and sensual temptation can effect, in endearing a home which is bright even amidst the gloom of poverty such a man does good as well as the most eloquent writer that ever wrote. If there were a few patriarchs of the people such as this, their beneficial influence would soon be sensibly felt by society at large. A life well spent is worth any number of speeches; for example is a language far more eloquent than words: it is instruction in action wisdom at work.

A man's daily life is the best test of his moral and social state. Take two men, for instance, both working at the same trade and earning the same money; yet how different they may be as respects their "actual condition! The one looks a free man; the other a slave. The one lives in a snug cottage; the other in a mud hovel. The one has always a decent coat to his back; the other is in rags. The children of the one are clean, well-dressed, and at school; the children of the other are dirty, filthy, and often in the gutter. The one possesses the ordinary comforts of life, as well as many of its pleasures and conveniences perhaps a well-chosen library; the other has few of the comforts of life, certainly no pleasures, enjoyments, nor books. And yet these two men earn the same wages. What is the cause of the difference between them?

It is in this: The one man is intelligent and prudent; the other is the reverse. The one denies himself for the benefit of his wife, his family, and his home; the other denies himself nothing, but lives under the tyranny of evil habits. The one is a sober man, and takes pleasure in making his home attractive and his family comfortable; the other cares nothing for his home and family, but spends the greater part of' his earnings in the gin-shop or the public-house. The one man looks up; the other looks down. The standard of enjoyment of the one is high, and of the other low. The one man likes books, which instruct and elevate his mind; the other likes drink, which tends to lower and brutalize him. The one saves his money; the other wastes it.

‘The root of all domestic prosperity, the main-stay of all domestic comfort, is the wife. There can be no thrift, nor economy, nor comfort at home, unless the wife helps; and a working-man's wife, more than any other man's, for she is wife, housekeeper, nurse, and servant, all in one. If she be thriftless, putting money into her hands is like pouring water through a sieve. Let her be frugal, and she will make her home a place of comfort, and she will also make her husband's life happy, if she do not lay the foundation of his prosperity and fortune.

Method is the hinge of business; and there is no method without punctuality. Punctuality is important, because it subserves the peace and good temper of a family. The want of it not only infringes on necessary duty, but sometimes excludes this duty. The calmness of mind which it produces is another advantage of punctuality. A disorderly man is always in a hurry. He has no time to speak to you because he is going elsewhere; and when he gets there, he is too late for his business; of he must hurry away to another before he can finish it. Punctuality gives weight to character.

Because I could not stop for Death

Because I could not stop for Death, 
He kindly stopped for me; 
The carriage held but just ourselves 
And Immortality.

We slowly drove, he knew no haste, 
And I had put away 
My labor, and my leisure too, 
For his civility.

We passed the school where children played, 
Their lessons scarcely done; 
We passed the fields of gazing grain, 
We passed the setting sun.

We paused before a house that seemed 
A swelling of the ground; 
The roof was scarcely visible, 
The cornice but a mound.

Since then ‘t is centuries; but each 
Feels shorter than the day 
I first surmised the horses’ heads 
Were toward eternity.


              -Emily Dickinson 

A LIGHT exists in spring

  
A LIGHT exists in spring      
 Not present on the year        
At any other period.   
  When March is scarcely here           
           
A color stands abroad        
  On solitary hills        
That silence cannot overtake, 
  But human nature feels.       
           
It waits upon the lawn;          
  It shows the furthest tree             
Upon the furthest slope we know;     
  It almost speaks to me.        
           
Then, as horizons step,           
  Or noons report away,         
Without the formula of sound,                  
  It passes, and we stay:         
           
A quality of loss         
  Affecting our content,         
As trade had suddenly encroached   
  Upon a sacrament.           
                      
                      -   Emily Dickinson
