The electric motor is the electric machine within the ceiling fan that converts electrical energy into mechanical energy.

History Of Ceiling Fan The invention of ceiling fans was a very significant contribution to mankind. It is the simplest and most affordable means to keep yourself cool in hot and humid climate. Though today we have the electrical version of the ceiling fan, it dates back to almost BC.

Ceiling Fan Working

Introduction to Construction of Ceiling fan. This motor comprises two parts that are stator and rotor. The stator, build up of laminated silicon steel, uses two windings termed as starting and running windings located 90 degree electrical apart. The starting torque relies on sine of angle among starting winding and running winding current. Thus Capacitor is used generate needed phase shift among these current and therefore to generate high starting torque and will be connected in series with starting winding. Generally in ceiling fan, an electrolytic capacitor of 2.

Components And The Working mechanism of a ceiling fan

A ceiling fan is a mechanical fan mounted on the ceiling of a room or space, usually electrically powered , that uses hub-mounted rotating blades to circulate air. They cool people effectively by increasing air speed. Fans do not reduce air temperature or relative humidity, unlike air-conditioning equipment but create a cooling effect by helping to evaporate sweat and increase heat exchange via convection. Fans may add a small amount of heat to the room due to friction and waste heat from the motor. Fans use significantly less power than air conditioning as cooling air is thermodynamically expensive.

The ceiling fan is the most ignored angel of our lives. We always take it for granted. Come inside the room switch it on and just ignore it. Jokes and philosophy apart, have any of us given a serious thought on how a ceiling fan works so tirelessly and efficiently. How does a heavy duty domestic appliance like a ceiling fan actually work? Before we jump on to the details lets dig into the history of ceiling fans a bit. The first generation of ceiling fans was not even powered by electricity.

Installing a ceiling fan is easy , according to how-to videos and breezy online tutorials. But these instructions assume that an electrical box rated to hang 70 pounds of fan is just sitting in the ceiling, mounted to a joist on bolts strong enough for chin-ups. Sorry, but unless you're replacing an existing fan, that box isn't in place yet. What is there, most likely, is a basic lighting fixture connected to someone else's electrical work—a pile of wiry pigtails bearing a strong resemblance to a can of worms.

 Он мертв? - спросил директор. - Да, сэр. Фонтейн понимал, что сейчас не время для объяснении.

 Северная Дакота, - вслух произнесла она, пытаясь своим умом криптографа проникнуть в скрытый смысл этого имени.  - Что говорится в его посланиях на имя Танкадо. - Понятия не имею. КОМИНТ засек лишь исходящую почту. В данный момент мы ничего не знаем про Северную Дакоту, кроме анонимного адреса.

 У вас испуганный вид, - сказала Сьюзан.

Беккер предпринял последнюю попытку: - Мистер Клушар, я хотел бы получить показания этого немца и его спутницы. Вы не скажете, где они могли остановиться. Клушар закрыл глаза, силы покинули. Он едва дышал.

Сотрудник лаборатории систем безопасности не стал выдавать дежурного. - Я поменялся сменой с новым сотрудником.

Нам нужны указания. ГЛАВА 114 - Обыщите их еще раз! - потребовал директор. В отчаянии он наблюдал за тем, как расплывчатые фигуры агентов обыскивают бездыханные тела в поисках листка бумаги с беспорядочным набором букв и цифр. - О мой Бог! - Лицо Джаббы мертвенно побледнело.

Но Мидж эта ситуация явно доставляла удовольствие.

Что вы делаете. Беккер понял, что перегнул палку. Он нервно оглядел коридор.

 Нет. Я же объяснил тебе, что он зашифрован. Сьюзан, в свою очередь, удивил ответ шефа.
