PCT No. PCT/SU81/00032 Sec. 371 Date Dec. 7, 1981 Sec. 102(e) Date Dec. 7, 1981 PCT Filed Apr. 10, 1981 PCT Pub. No. WO81/03092 PCT Pub. Date Oct. 29, 1981.An electric drive includes two d.c. electric motors electrically connected therebetween, each of them comprising a stationary former of magnetic field, a movable portion 1,2, an excitation winding 3,4, and an armature winding 5. A commutating device 25 is connected to the armature winding 5. The former of magnetic field is a ferromagnetic strip 22 or 23 provided with pole-forming projections disposed in two rows in the chessboard order. The armature winding 5 is common for both the motors, its sections being uniformly distributed among the motors, and the ends of the sections are led out at the side of one of the motors and connected to the commutating device 25 for forced commutation of the sections in a function of a relative location of the ferromagnetic modules of the movable portions and pole-forming projections.
