Abstract

PURPOSE:To obtain a high load torque even at the time of an overload without overexcitation of a load motor by regulating the terminal voltage of an induction motor relative to the load torque to meet the characteristics of the load. CONSTITUTION:The current of the U-phase of 3 phases is detected by a current detector 14, the counterelectromotive voltage of a load induction motor is detected by a counterelectromotive voltage arithmetic circuit 15 from the U-phase voltage reference VUX of the 3 phases, and they are averaged by a rectifying circuit 16, thereby obtaining an output V2. On the other hand, the U-phase voltage reference VUX of the 3 phases are rectified and averaged by a rectifying circuit 17, thereby obtaining an output V1. The difference between the output voltages V1 and V2 is calculated by a subtractor 18, thereby obtaining an output V3. A voltage which is proportional to the output voltage V3 is added by a regulating resistor 19 to the input of a voltage pattern circuit 6.
