Thermal characteristics of motor

While operating a three-phase motor with the same capacity as the FR-A500 (0.75 kW) under V/F control, the motor becomes too hot over continuous ON/OFF and gear change operations and the speed fluctuates within approximately 10 Hz range.
Please send a graph of relationship between the motor temperature and torque or speed precision, if any.

Answer

Basically, when the motor temperature goes higher, the motor rotation speed goes lower.
The motor rotation speed also changes when the inverter input power supply state or load state changes.
Since relationship between the motor temperature and torque or speed precision depends on the motor used, contact the manufacturer of the motor.
