The difference between three-phase asynchronous motor and variable frequency motor

Released Date: Apr 23,2021 Article Source: Shengzhou Senli Motor

The ordinary three-phase asynchronous motor can be equipped with a frequency converter, but the fan of the ordinary motor is installed on the motor shaft, so when the motor speed is low, the heat dissipation effect will become worse; According to the constant frequency and constant voltage design, it can not fully adapt to the requirements of frequency conversion speed regulation, but the frequency conversion motor can solve this problem. The difference between the variable frequency motor and the three-phase asynchronous motor is that the cooling fan of the former is not fixed on the shaft of the motor, but is powered by the power frequency power supply alone

NormalThree-phase asynchronous motorIt is possible to install a frequency converter, but the fan of the ordinary motor is installed on the motor shaft, so when the motor speed is low, the heat dissipation effect will become worse; According to the constant frequency and constant voltage design, it can not fully adapt to the requirements of frequency conversion speed regulation, butVariable frequency motorCan solve this problem very well.

Variable frequency motorwithThree-phase asynchronous motorThe difference is that the cooling fan of the former is not fixed on the shaft of the motor, but is powered by the power frequency power supply alone, even if the motor is5HZIf the frequency is running, the cooling fan will still be50HZThe speed of operation;

Three-phase asynchronous motor

The latter cooling fan is fixed on the motor shaft, and the motor is synchronous rotation, that is, the speed is the same, here is the previous mentioned when the motor speed is low, it is often said that the low-frequency operation, the fan is also running at a low speed, the cooling capacity is greatly reduced, then the heat generated by the motor can not be distributed, and the motor will burn seriously.
