Abstract

PURPOSE:To prevent the continuation of a dangerous vibration of a rotary electric machine by increasing acceleration torque when the speed of a motor becomes in the vicinity of the dangerous speed, thereby accelerating the passage of the vicinity of the dangerous speed of the motor. CONSTITUTION:A speed controller 6 produces a difference between the output of a speed command pattern generator 4 and the output of a rotating speed detector 5. A current controller 10 controls a power rectifier 121 by the differnce between the output of a speed controller 6 and the output of a 3-phase AC power source 7 detected by a current transformer 8. A logic circuit 13 controls a power inverter 122 by the output of a distributor 3. When the speed in the vicinity of dangerous speed is detected, a rotating speed detector 5 opens a contact 15 for the predetermined period of time, and the output of a current setting unit 14 is applied to the controller 10. In this manner, the continuous time of the dangerous vibration can be shortened.
