The motor is the key power device of the screw air compressor, and it plays a major role in the components of the air compressor. Everyone knows that air compressors are divided into ordinary power frequency and permanent magnet variable frequency, so is there any difference between the two motors?
Generally, ordinary motors and variable frequency motors are naturally different. The biggest difference is that ordinary motors can only work under a stable condition, while variable frequency motors can make corresponding adjustments in advance according to the load condition of the generator set. In addition, the differences between the two are also reflected in the following aspects:
1. The variable frequency motor adds an electromagnetic induction load to the general motor.
2. The speed ratio of an ordinary motor cannot be changed. It has a stable speed ratio, while the motor of a variable frequency screw air compressor can adjust the speed ratio to achieve energy conservation and environmental protection.
3. Because the insulation layer material used in ordinary motors is weak, the insulation performance is usually worse than that of variable frequency motors. Secondly, the thickness of the slot insulation layer is not as thin as that of variable frequency motors.
4. For the same size, the iron core cross section of a general motor is small and the number of turns is small. The cable diameter is small and the insulation layer is low. The opposite is true for variable frequency motors.
The normal operation of the screw air compressor cannot be separated from the motor. The above is the key difference between the permanent magnet motor and the ordinary motor. Naturally, the differences between the two are far more than these. When it comes to this, everyone can’t help but think of power frequency air compressors and permanent magnet variable frequency air compressors. Their differences are also one of the characteristics of permanent magnet variable frequency air compressors. DC air compressors and permanent magnet variable frequency air compressors have their own advantages and disadvantages. When selecting, you can choose according to the company’s production and manufacturing gas fluctuations.
