Abstract

An electrical motor-control device is for electrical equipment. It has a drive mechanism including an electric motor and a movement transformation mechanisn including an endless screw on which is installed a linearly displaceable nut connected with slight play to an operating member of the electrical equipment. A torque limiter is inserted between the drive mechanism and the movement transformation mechanism. The torque limiter comprises a disc made of rough material integral with a worm screw and has component parts in the form of segments of a ring connected by springs clamping the said disc made of friction material. Applications: remote control of electric circuit-breakers.
