FAQ
What is the difference between variable frequency motors and ordinary motors?
1. The insulation strength of the motor
At present, many small and medium-sized inverters adopt PWM control methods. Its carrier frequency is about several thousａnd to ten kilohertz, which makes the motor stator winding to withstａnd a very high rate of voltage rise, which is equivalent to imposing a steep impulse voltage on the motor, which makes the motor’s turn-to-turn insulation more resistant. The harsh test. In addition, the rectangular chopping impulse voltage generated by the PWM frequency converter is superimposed on the motor operating voltage, which poses a threat to the motor's ground insulation, and the ground insulation will accelerate its aging under repeated impacts of high voltage.
2. Harmonic electromagnetic noise and vibration
When an ordinary asynchronous motor is powered by a frequency converter, the vibration and noise caused by electromagnetic, mechanical, ventilation and other factors will become more complicated. The time harmonics contained in the variable frequency power supply interfere with the inherent spatial harmonics of the electromagnetic part of the motor to form various electromagnetic exciting forces. When the frequency of the electromagnetic force wave is consistent with or close to the natural vibration frequency of the motor body, resonance will occur, thereby increasing noise. Due to the wide operating frequency range of the motor and the wide range of rotation speed, the frequency of various electromagnetic force waves is difficult to avoid the natural vibration frequency of each component of the motor.
