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.

In a rope pull hoist, useful for operating motor vehicle doors, windows, and sliding roofs, and driven by a permanent magnet motor having a flat housing, the motor having a shaft extending into a gear box and carrying a worm, a worm gear driven by the worm and coupled to a rope drum for engaging a closed rope loop, the improvement comprising: the motor comprising a rotor mounted in an axially oriented, magnetically nonconductive frame along with at least one permanent magnet; pole plates for the motor being in close contact with either side of the frame and serving as flat housing halves, the housing so formed having a given thickness; the worm wheel and the rope drum coupled to it being rotatably mounted on a shaft in the gear box; and the gear box having a thickness less than the given thickness of the electric motor housing.
