Ceiling fan motors mostly use capacitor motor, a few also use covered pole motor. It is characterized by the stator rotor, the stator and the ceiling fan shaft is connected and fixed on the derrick. When the outer rotor rotates around the stator, it drives the end cover and the room to rotate. Due to the large diameter of the fan blade of the hanging room, the speed of the motor should not be too high. The stator of the motor is formed by overlapping riveting of silicon steel sheet, and the middle is pressed into the stator shaft to form the stator core. The winding wire is fixed in the groove of the outer circle of the stator.
Precautions when using ceiling fans:
1, ceiling fan use time is too long, to check all kinds of parts, especially derrick, screws, blades, etc., if there are these problems, can be said to bring some hidden dangers to the user, so find abnormal, must be timely maintenance, if the parts are damaged, must be replaced in time.
2, open the ceiling fan, but also do the test run work, is to start it for a few minutes, and then people can not stand under the ceiling fan, the ceiling fan can be normal operation, then there is no problem, can continue to use, if there is smell or sound, we have to find out the reason.
3. When the ceiling fan is opened, it should be adjusted to which gear is needed. It can not be adjusted one by one, otherwise it will not only cost electricity, but also easily cause damage to the ceiling fan. Usually, the ceiling fan can not be turned on too often to prevent the motor from overheating, which will also affect the service life.
4. The operation time of ceiling fans should not be too long, generally kept at about 3 hours. Turn off and rest for a while, and then open for use.
Ceiling fan motors which include forced air ventilation and heat dissipation systems to provide significantly reduced motor operating temperatures, improved motor component tolerances, lower manufacturing costs, and ease of assembly. The ceiling fan motor is of the inside-out type and includes an impeller mechanism associated with at least one of the upper or lower portions of the motor casing for drawing substantial volumes of air into the casing, across the stator, and through the opposite portion of the motor casing. The motor casing components may be formed from cast aluminum. Alternatively, the entire casing and rotor is of unitary integrally cast aluminum. One of the end faces of the motor casing may include integrally cast blade ramps.
