The fan starts slowly and waits for a long time to turn up

It may be that the bearing wear is large and dry, making the resistance to rotation larger. Regular cleaning and dripping of lubricating oil can be done. Or the electric fan has been used for a long time, and the capacity of the starting capacitor has decreased, resulting in a significant reduction in the starting torque and a longer starting time. It can be solved by replacing the capacitor of the same type.

1. When using an electric fan, the fast gear should be used first, and the 220V voltage is directly applied to the motor, which not only saves the step-down loss of the governor, but also makes the motor start up enough, and the motor temperature will not rise significantly. After the speed is normal, then adjust to the slow gear to run. This not only helps protect the fan, but also saves electricity.

2. Regular maintenance of electric fans is an important condition to prolong the service life of electric fans. In order to keep the appearance of the fan clean and beautiful, it is best to use a soft cloth to wipe off the dust and oil, and wax it to keep it shiny and beautiful.

3. After the electric fan runs, the temperature of the fan head begins to rise. This is a normal phenomenon. Because the electric fan itself has good heat dissipation conditions, for example, the front and rear covers of the fan head have a certain number of ventilation holes. The airflow keeps the heat out. Therefore, when the heat generated by the fan head is equal to the heat dissipated, the temperature will not increase any further.
