What Are The Reasons Why The Living Room Ceiling Fan Slows Down?

In the hot summer, the living room ceiling fan plays an incomparable role in our lives. However, the living room ceiling fan will fail after a period of use. Obviously, the speed of the ceiling fan slows down. There are many reasons for the slow speed of ceiling fans, but in summary, there are four main reasons.

1. The governor is broken

If it is a new purchase, it may be that the ceiling fan governor is broken.

2. Bearing lack of oil

If the fan bearing is short of oil, you can add some oil (you have to use butter). If it is a short circuit between turns, the motor will overheat and you must rewind it. To determine whether there is a problem with the bearing, you can listen to the sound. If there is a problem with the bearing, call professional maintenance personnel to repair it.

3. Decreased capacitance

Most household appliances use single-phase power supply, but electrical appliances with motors must be powered by two-phase or more than two-phase power supplies. What should be done? The designer has long thought about it.

In a single-phase circuit, connect a large Capacitors, because large capacitors have a hysteresis effect on the current of the AC power supply (the circuit with capacitors is 90 degrees behind the current of the circuit without capacitors), so that the original one-phase input becomes two-phase, and the motor can work normally . The household appliances we use (single-phase) are based on this principle.

The capacitance value of the capacitor becomes smaller or lack of oil and friction or inter-turn short circuit. 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. This is a synchronous motor, and the speed is determined by the frequency of the power supply.

If it is said that there is no page 100 revolutions, it will also be 100 revolutions after installing the blades. If a few more leaves are installed, the load is too heavy, the motor cannot start, and the spring keeps repeating the help. start up.
