A stator 3 of a motor 1 is pivotally supported on a stationary system 5 by an elastic member 28, 11a, 42 provided along the circumferential direction of the stator 3, and a detector 11 for detecting a rotational force of the stator 3 is provided to execute the control of stopping, accelerating, dece

A stator 3 of a motor 1 is pivotally supported on a stationary system 5 by an elastic member 28, 11a, 42 provided along the circumferential direction of the stator 3, and a detector 11 for detecting a rotational force of the stator 3 is provided to execute the control of stopping, accelerating, decelerating or reversing the operation of the motor 1 based on a detection signal from the detector 11. When the motor load is increased, transmission of torque from the action system 3 to the reaction system 4 of the motor 1 is cut off, and consequently the stator 3 itself of the motor 1 pivots with respect to the stationary system 5 as a reaction. In this stage, the detector 11 detects the rotational force of the stator 3 to stop, accelerate, decelerate, or reverse the operation of the motor 1.

[ What is claimed is:] [1.] An electric motor in which a stator side member of a motor is pivotally supported on a stationary system by an elastic member, and a detection means from detecting a rotational force of the stator side member is provided so that the control of stopping, accelerating, decelerating or reversing operation of a motor drive system is executed based on a detection signal of the detection means, wherein a protuberance section is provided on an outer peripheral surface of said stator side member, and whereina recess section opposite to said protuberance section is formed at the stationary system, said recess section having end surfaces, whereby said elastic member is disposed between the protuberance section and the recess section and compressed between the protuberance section and end surfaces of the recess section in a rotational direction of said stator side member correspondingly as said stator side member pivots.
