How long does it take to apply for the electrician IC certificate in Shijie, Dongguan in 2016? Are there any good training institutions?

Motor is the general term for electric motors and generators. It is usually divided into two categories: one is DC motor and the other is AC motor. DC motors are divided into two categories: DC motors and DC generators, while AC motors are divided into two categories: asynchronous motors and synchronous motors. Asynchronous motors are further divided into three-phase asynchronous motors and single-phase asynchronous motors. In view of the mechanical parts of various types of motors

Check whether the bearings are loose or stuck. Check whether the air duct is blocked and whether the fan blades and heat sinks are intact. For motors with larger capacities, there is usually an air gap measuring hole on the end cover. Through the air gap measuring hole, it can be detected whether the average value of the air gap unevenness is within <>%. During power-on operation, check whether the motor is normal by touching, listening, smelling and observing. Once an abnormality is discovered, the power supply should be cut off immediately to prevent the fault from expanding. After the inspection has roughly determined the nature of the fault and clarified the scope of the repair, the motor can be disassembled for further detailed inspection and repair.
