ABSTRACT:
A motor vehicle hoist has a closed rope loop which is driven by a permanent magnet electric motor having a flat housing and a worm with a worm wheel. The worm is fastened to an end of the motor shaft which extends into an adjacent gear box, and turns a rope drum. The motor stator includes an axially oriented, magnetically nonconductive frame, which holds the rotor and at least one permanent magnet and which supports housing halves which serve, on both sides, as pole pieces. The worm wheel and rope drum are rotatably mounted on a common axis in the gear box. The motor is useful for opening windows, doors, and sliding roofs of vehicles.
