1. The speed regulator is broken
If it is a newly purchased Industrial Fans, the speed regulator of the Industrial Fans may be broken.
2. Bearings are short of oil
If the Industrial Fans bearing is short of oil, you can add some oil (use butter). If there is a short circuit between turns, the motor will overheat. You need to wind it from the beginning to see if there is a problem with the bearing. If there is a problem with the bearing, you can hear abnormal sounds. If there is a problem with the bearing, you need to call a professional repairman to repair it.
3. Reduced capacitance
Most household appliances are powered by a single phase, but appliances with motors require two or more phases of power supply. What should I do? In fact, the designer has already thought about it. A large capacitor should be connected in parallel in the single-phase circuit. Because the large capacitor is related to the AC power supply, it has a hysteresis effect on the current, so that the original one-phase input becomes two-phase, so that the motor can work normally. We All household appliances used (single phase) are based on this principle.
If the capacitance value becomes smaller, the friction is large due to lack of oil, or the turns are short-circuited, the capacitance value can be increased appropriately, but not too large, otherwise the motor temperature will rise and affect the motor life. This is a synchronous motor, and its speed is determined by the power frequency. It is decided that if the page does not rotate 100 times, it will also rotate 100 times after installing the blades. If too many blades are installed, the load is too heavy and the motor cannot start, and the tension spring will continue to repeat to help start.
