Abstract

PURPOSE: To stabilize the torque characteristic by performing compensation for a slip frequency control loop with a temperature compensator detecting the temperature of a motor.
CONSTITUTION: The output of a torque setter 1 is converted into a current command and a slip frequency command separately with a torque-current converter 2 and torque-slip frequency converter 6. The current command is inputted into an inverter controlling circuit 11 with the output of a current detector 3 via a subtractor 4 and a current controlling amplifier 5. The slip frequency command is added 10 to a rotation frequency of the motor after temperature compensation via a frequency compensator 9 and then, inputted into the circuit 11. The outut voltage is controlled to have the motor current coinciding the current command while the output frequency is controlled to have the slip frequency coinciding the slip frequency command after compensation.
