from the point of view of the operator, the frequency conversion motor is a poor quality motor, and the ordinary motor is the good motor.

2, as a result of the inverter output pwm adjustable wide wave simulation sinusoidal alternating current (ac), contains a lot of harmonic, after reactor filter in general need to enter ordinary motor, otherwise ordinary chance fever;

3, in order to meet the inverter output pwm adjustable wide sinusoidal alternating current (ac) contains a lot of harmonic wave simulation, specialized production of variable frequency motor, its role in fact can be interpreted as reactor with common motor;

4, that is to say, with the power of variable frequency motor is bigger than ordinary motor iron core section, coil number of turns, wire diameter, higher insulation, a special cooling fan motor;

in order to adapt to the need of weak magnetic speed adjustment, the bearing capacity and high-speed rotor dynamic balance are considered.
