In the main structure of the screw air compressor, there is an important part, that is, the motor, the motor is generally divided into ordinary motor and variable frequency motor. Ordinary motors can only operate stably under rated conditions, while variable-frequency motors do not. It can operate at stable speeds according to different loads and requirements. So, what is the difference between the variable frequency motor and the ordinary motor of the screw air compressor?
Screw air compressor variable frequency motor 1, ordinary motor speed is fixed, it can not be adjusted, and variable frequency motor can flexibly adjust the speed, so as to achieve effective energy saving purposes and effects.
2, the same size of the motor, the general motor core cross section should be small and small number of turns, small diameter, low insulation capacity, frequency conversion motor is just the opposite.
3, ordinary motor slot insulation is poor, the quality of the insulation material used is also relatively poor, slot insulation thickness is not enough.
4. The frequency conversion motor increases the electromagnetic load on the basis of the ordinary motor.
The above are several important differences between the screw air compressor inverter motor and the ordinary motor. Of course, the difference is far more than these. The user can consult the air compressor salesman or air compressor professional maintenance technicians will get a more detailed answer .
