Questions about using an inverter with a regular motor
Thread Content
Two small single-screw pumps, 1.5KW, grade 6; ordinary motors were used at that time, but now the client wants frequency converters to be used. After operation, they overheat and shut down after 1–2 hours. It works fine without an inverter – why is that? Are ordinary motors not effective when paired with frequency converters?
I know a little about this. Motors are also divided into variable-frequency motors and non-variable-frequency motors. Even if it’s not a variable-frequency motor, a frequency converter can still be used, but there are some drawbacks, such as poor heat dissipation. This is likely the problem with your motor
