ABSTRACT:
A drive device consists of at least two three-phase electric motors arranged paraxially alongside of each other, and each of the stators (6) thereof has its own winding (11). A single stack of laminations integrally serves each stator (6), in that each lamination is cut-out to serve plural stators. The winding (11) and the lay-out of stator-slots (7) and the supply-phase connection to each phase of the three-phase supply network is so selected for all motors that the magnetic-flux maxima of the same polarity in the yokes (9) of the stators (6), which maxima rotate in the direction of rotation of the motor, pass at different times through the location of minimum spacing between directly adjacent stators (6).
