Ceiling Fans are direct driven mostly using single-phase Inductionmotor. Motors have windings wound for 18, 20 or 22 poles, resulting in to lower operating speeds (Most common: 18 pole). The rotor resistance is very high for wide speed control range using the stator voltage control.
There's nothing better than getting home from work on a sweltering afternoon, switching on the ceiling fan, and relaxing in comfort with that fan passing over your head, cooling down your hot, stressful day. Ceiling fans can make life a great deal more comfortable, and they can save money on cooling bills as well. In fact, if you've got good ceiling fans in a few rooms of your house, you probably don't even need an expensive, bulky air conditioning unit. More than likely, you've thought about how great ceiling fans can be. Not only do they cool down rooms, but a beautiful ceiling fan in the right style and color can change the entire ambience of a room. A ceiling fan is defined as a mechanical fan, usually electrically powered, that is suspended from the ceiling of a room that uses rotating paddles to circulate air.
This type of fan is wired through the ceiling and connected to the wire that controls either a remote box or a switch on the wall for operating. 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. This action causes the motor coils to spin. As the coils are spinning, the fan captures this spinning motion, transferring it to the fan blades. The slicing of the air caused by the fan blades is what pushes the air downward, causing the breeze created by the ceiling fan. This whole process circulates the air through the room, as air moves in to replace the air that has been pushed down from the ceiling. Ceiling fans work are so effective because of the fact that hot air rises. As the hot air reaches the ceiling, it builds up the heat in the entire room. A fan mounted on the ceiling forces this hot air away from the top of the room, and this action leaves room for more hot air to rise, thus circulating the air in the room causing the breeze. It is this action that can make ceiling fans effective in any season.
