1, from the point of view of power frequency, frequency conversion motor is inferior motor, ordinary motor is a good motor;

2. Because the PWM width modulation wave output by the frequency converter mimics sinusoidal alternating current, which contains a lot of harmonics, it generally needs to be filtered by the reactor before entering the ordinary motor, otherwise the ordinary electric machine will heat up;

3, in order to adapt to the output of the frequency converter PWM width wave analog sinusoidal alternating current contains a large number of harmonics, the special production of frequency conversion motor, its role can actually be understood as a reactor plus ordinary motor;

4, that is to say, the same power of the frequency conversion motor than ordinary motor core section is larger, more coil turns, wire diameter to large, high insulation, special cooling fan motor;

5. In order to meet the needs of weak magnetic speed regulation, bearing capacity and high-speed rotor dynamic balance are considered;

6, this frequency conversion motor does not have better torque characteristics, just to overcome the ordinary motor is not suitable for PWM width wave simulation sinusoidal AC needs!

7, if the frequency conversion motor does not have the above characteristics and requirements, it is false frequency conversion motor
