Can a three-phase variable-frequency motor adjust the power to above 50HZ? !
Thread Content
Domestically produced variable-frequency motors. The nameplate of the three-phase variable-frequency motor indicates that the constant torque frequency range is 5–50 Hz, while the constant power frequency range is 50–100 Hz. Power is 110 KW, and the rated current is 201 A. The actual operating current is 140A, and it has been adjusted to 50HZ. This motor is equipped with a fan, but the air flow volume is not sufficient at the moment. Is it possible to increase the frequency further in order to raise the current, increase power, and thus boost the air flow volume? Please give me some advice.
The frequency can be increased to boost airflow, but care must be taken to ensure that the current does not exceed the rated value. I was once transferred to 55HZ
Okay, now 50-something, 60-something – all are fine. Thank you.
Continue to increase the frequency in order to raise the current, boost power, and increase airflow
