ABSTRACT:
A control device for an elevator, which is made up of a position detecting device for detecting the position at which rotary elements such as the armature of an electric motor and sheaves produce vibration torque and a cancellation signal generating circuit. The circuit is employed for generating a cancellation signal to cancel the vibration torque in response to the output of the position detecting means. A control circuit is used for applying current necessary for cancelling the vibration torque to the motor by receiving the cancellation signal. Even if the vibration is caused by the eccentricity of the rotary elements or by the torque ripples generated by the armature of the motor, it is not sensed by the persons in the elevator cage.
