1. The governor is broken
If it is a new purchase, it may be that the governor of the factory ceiling fan is broken.
2. Oil shortage of the bearing
If the fan bearing is short of oil, it can be oiled (with butter). Judge whether there is a problem with the bearing and listen to the sound. If there is a short circuit between turns, the motor will overheat, so it should be wound from the beginning. If there is a problem with the bearing, call professional repair personnel to repair it.
3. Capacitance drop
What should we do? A single-phase power supply powers most household appliances, but it is necessary to have a two-phase or more power supply for electric appliances with motors. The designer has long thought that in a single-phase circuit, a large capacitance is connected in parallel because the large capacitance has a lag effect on the current (the circuit with capacitance is 90 degrees after the current without capacitance), so that the original one-phase input becomes two phases, the motor can work normally. This is the principle of all the single-phase household appliances we use.
This is a synchronous motor; the frequency of the power supply determines the rotation speed. If the capacitance value becomes small or the oil shortage friction is large, or between turns circuit is short, the capacitance value becomes small, which can appropriately increase the capacitance value but not too large. Otherwise, the temperature of the motor will increase, which will affect the service life of the motor. If there is no page for 100 turns, it will also be 100 turns after the blade is installed. If there are more leaves installed, the load is overweight, the motor cannot be started, and the tension spring repeatedly assists in starting.
In large-scale energy-saving factories, the natural breeze generated by ceiling fans blows on the human body, promoting the evaporation of sweat to take away the heat, thus cooling the human body and bringing a cool feeling. Usually, this cooling feeling can reach 5-8℃. The three-dimensional natural breeze blown by ceiling fans in large factories makes the human body more comfortable because, on the one hand, the three-dimensional blowing on the human body in all directions makes the evaporation area of the human body reach the maximum.
