Claims

[Scope of utility model registration request]

A rotor shaft is rotatably supported in a cylindrical bracket, and an inner ring of one bearing is attached to an intermediate shaft or the rotor shaft that connects the output shaft driven by the rotor shaft and the rotor shaft. A pair of annular biasing plates are arranged back to back and are fixed and movable in the axial direction of the bracket, a part of which engages the side surface of the outer ring of the bearing, and which fits externally into the outer ring of the bearing. springs are arranged between the biasing plates and the side wall of a recess formed on the inner wall of the bracket to accommodate the biasing plates, and the rotor shaft and the output shaft or the rotor shaft and the intermediate shaft are compressed. are connected by screws with large lead angle screws at each end, and when a certain load torque is applied to the output shaft, the shaft moves along with the rotor shaft or intermediate shaft in the axial direction due to the action of the screws. 1. An electric motor comprising: a detection device that detects the amount of movement of a biasing plate that moves in the direction; and an electromagnetic brake that locks a rotor shaft only in the rotational direction according to the amount of movement.
