Can ordinary motors be matched with inverters?
Can, but not the long run under low frequency, which can't run for a long time in 30 hz, because: 1. The inverter output is not a standard sine wave, the large amount of harmonic, harmonic exacerbate motor hair machine; The cooling fan of the normal motor and the motor coaxial, the cooling fan speed decreases and the cooling effect is decreased when the motor is running at low speed.
Ordinary motors can also be equipped with a frequency converter, and many of the older plants are now being upgraded with a frequency converter on the old motor.
You can have a converter, but you have to worry about the heat of the motor, because the blades and rotor of the ordinary motor are a shaft, and it's better not to run at low speeds
