ELMOTOR MED AUTOMATISKT VERKANDE BROMS

摘要

An electric motor with automatically acting brake, which possesses a brake element including an armature plate and displaceable on the rotor shaft against a helical spring, and released by the magnetic field of the rotor. The brake element axially guides a disc possessing guide grooves situated between it and the armature plate. The inclined planes of the disc are facing towards the rotor and extending around the rotor shaft in the form of annular segments are disposed axially symmetrically on this disc, which are pressed by a prestressed spring bearing against the brake element onto a starting pin inserted into the rotor shaft.
