The purpose of this invention is to reduce the number of interconnecting cubicles for three speeds of the electromotor rotor rotations from three to one. The aforesaid purpose is achieved by connecting three outer coils (1,2,3) and three inner coils (4,5,6) of the stator winding and three phases (U, V, W) of the power network to contacts of the connector (7) arranged in the same manner as the contacts of the interconnecting cubicle (8), in five rows and five columns of identical pitches, where three rotor rotation speeds correspond to three positions of the interconnecting cubicle (8) moved over by 90 degrees.<IMAGE>
