Maintenance of Dynamic Electric Fan.
On the motor can move the electric fan, I am according to the actual situation, one step arrives. Instead of the routine maintenance described above. If the user says, the fan turns slowly first, then gradually gets faster. According to experience, the motor is usually slightly holding the shaft. The reason is that the electric fan is short of lubricating oil at the beginning. Directly Open the electric fan motor, in the front and rear axles on the linoleum plus enough sewing machine oil, generally can be repaired.
1. The Remote Control Electric Fan, on the electricity turns the breakdown elimination. Nowadays the Remote Control Electric Fan controls the executive component basically to be the silicon-controlled rectifier. From the principle, it can be seen that the thyristor is essentially equivalent to the thyristor breakdown of the switch is equivalent to the switch on. When you turn on the power, the fan will, of course.
2. For example, when a floor remote control electric fan is in use, the functions of the remote control are basically normal, but when the electric fan is turned off, there is a clear sense of vibration when the electric fan is not unplugged and the hand touches the electric fan, and the electric fan makes a buzzing sound, at night it is especially obvious that the electric fan blades are also turning slowly. Because each control function basic normal explanation, MCU normal, from the above principle can know that SCR has the fault.
