Introduction to Construction of Ceiling fan.

The electric motor is the electric machine within the ceiling fan that converts electrical energy into mechanical energy. The ceiling fan capacitor torques up the electric motor, allowing it to start and run. An electrical current reaches the motor and then enters coils of wire that are wrapped around a metal base. As this current passes through the wire, a magnetic field is caused that expends force in a clockwise motion that actually changes the electric energy into mechanical energy.

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. In the winter a ceiling fan can also be used to bring warm air, which naturally rises, back down to occupants.

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. Replacing it involves clearing out a wrist-size hole and then reaching back in to mount a metal box, clamp the wires and secure their connections, all while never once getting a clear look at what you're doing. Now, many amateurs can hang a pot rack or an overhead planter, and most can wire a receptacle, but few can do both at the same time.

Ceiling fan

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?

Беккер потянулся и дернул шнурок вызова водителя. Пора было отсюда вылезать. Дернул. Никакой реакции. Он дернул шнурок в третий раз, более резко.

 Вы не поставили в известность Лиланда Фонтейна. Терпение Стратмора иссякло. Он взорвался: - Сьюзан, выслушай .

 Да. Первая неделя оказалась последней. Солнечный удар и инфаркт. Бедолага. Беккер ничего не сказал и продолжал разглядывать пальцы умершего.

Он прислушался. Голоса звучали возбужденно. - Мидж. Ответа не последовало.

Очевидно, Хейл сумел высвободиться.
