Factories that produce AC motors and other ceiling fan motors factory, The reasons for the slow speed of the ceiling fan: 1. If the governor is damaged, if it is a newly purchased ceiling fan, and it turns slowly, it may be that the governor is broken.
2. Bearing lack of oil may also be caused by the use of the ceiling fan for a period of time and bearing lack of oil, which will also affect the speed. At this time, you can add some butter. If it is a short circuit between turns, the motor will overheat and need to be re-wound. How to judge is the problem of the bearing itself. One is listening to the sound, the noise is too loud. The second is to find professional maintenance personnel.
3. The detection of uneven voltage sharing generally requires professional maintenance personnel to use professional tools to check it out.
4. Fan blade problems Take a closer look at whether there are problems with the fan blades, such as whether it is deformed. If there is a serious deformation, it will also affect the speed.
5. Decreased capacitance capacity Household appliances mostly use single-phase power supply, but electrical appliances with motors must have two-phase or more than two-phase power supply. The capacitance value of the capacitor becomes smaller or the friction between the oil shortage and the turn is short, and the capacitance value becomes smaller. The capacitance value can be increased appropriately, but not too large, otherwise the temperature of the motor will increase, which will affect the life of the motor.
6. The motor of the electric fan has been in the dust for a long time. The electric fan will inhale some dust more or less, but don't underestimate it, it is the chief culprit of the wear of the rotating parts. When encountering this situation, the motor can be removed and cleaned. The motor of the electric fan is very simple and easy to remove, but be careful not to damage the insulating layer, just dry or blow dry.
