Three-phase asynchronous motor is divided into fixed frequency and frequency conversion, ordinary three-phase asynchronous motor, that is, fixed-frequency motor, then there are many small partners will have questions, can the fixed-frequency motor be used as a frequency conversion motor? Here is a simple understanding with Senli Motor Xiaobian.
Strictly speaking, the fixed frequency motor, that is, the ordinary three-phase asynchronous motor can not be used as a frequency conversion motor, because the two have certain differences in structure and the materials used, electromagnetic design.
The two also have differences in the heat dissipation system, ordinary three-phase asynchronous motor heat dissipation and speed is related, if the motor speed is fast so the heat dissipation effect will be good, but if the speed is slow, then the heat dissipation is slow, but the frequency conversion motor does not exist this problem.
After the ordinary motor and frequency converter, it is possible to achieve frequency conversion operation, but it is not a real frequency conversion motor. If you work in non-power frequency state for a long time, it may cause damage to the motor.
