Title: Controller for operation of induction motor
Inventor: KAWADA SHIGEKI
IPC: H02P27/06
Filed: 1978-12-30
Abstract: PURPOSE: To operate an induction motor stably when the motor rotates at a low speed by a system wherein the induction motor is driven by means of a pulse width modulation type inverter while a clamp circuit for clamping slip frequency instruction signals is mounted to the control system.  
     CONSTITUTION: Instruction speed and actual speed are compared and supplied to a slip frequency instruction signal generator 7, and the output passes through a clamp circuit 21 clamped by means of a slip frequency set circuit 23, is added to the acutal speed and is given to a pulse width modulation circuit 16 through a V-F converter 10. Meanwhile, comparison signals are transmitted to a multiplying circuit 14 through a limiter circuit 13, and the output is composed with the output of the converter 10 by means of a composite circuit 15. Consequently, operation in case of low speeds can be stabilized while slip frequency instruction signals are clamped, thus softening impact force in case of the orientation of a machine tool, then optimally controlling an induction motor.
