Abstract
A motor drive for a window lifter in motor vehicle doors has an integrated flat housing containing a permanent magnet DC motor and a worm gear driven by a worm on the extended motor shaft; the housing has two halves which are separable in the plane of the motor axis and which serve as the return yoke of the motor. A single permanent magnet is arranged in the space defined on two sides essentially by the motor rotor on the one hand and the worm gear on the other hand and each of the two housing halves serves as a pole plate.
