Can ordinary motors be controlled via frequency conversion?
Thread Content
Can ordinary motors be controlled via frequency conversion, or can frequency converters only control frequency-conversion motors? I have a Roots blower; it doesn’t seem to have an inverter-driven motor. Can I buy an inverter to enable variable frequency control?
No, that’s not good for the motor; over time it will affect its insulation properties
Over the years, the motors used in conjunction with frequency converters in China have mostly been ordinary motors.
Is it variable-frequency starting or variable-frequency control?
The start-up and control of the inverter are integrated.
They are integrated, but usually ordinary motors are used for variable-frequency starting; variable-frequency control to adjust the speed is not carried out frequently
When domestic companies switch their motors to variable-frequency control, they still use the ordinary motors originally in use. Practice has shown that there is no issue with speed regulation, provided that the maximum frequency remains below 50 Hz.
Ordinary motors can be controlled via frequency conversion
It’s no problem to change 50hz to 40; have you tried going even lower, such as to 20hz?
20Hz is also acceptable; the key is to use frequency adjustment to control and regulate the system according to its requirements
