In the electric motor/generator arrangement described in the specification, a hollow cylindrical generator rotor is mounted on an input shaft connected to an internal combustion engine and a hollow cylindrical electric motor rotor is connected to an output shaft. Both rotors have circumferential rings of permanent magnets of alternately opposite polarity, and the rings are disposed in axially-spaced relation. A stator has at least one switchable short-circuit winding arranged so as to be displaceable by a displacement device over a wide range adjacent to the permanent magnets of the rotors. Magnetic field sensors disposed between the permanent magnets in each ring detect the polarity of adjacent permanent magnets in the other ring, and the short-circuit winding is closed or opened as a function of the sensor signals. In this way, the direction of rotation of the output shaft can be changed and the rotational speed and the output torque of the output shaft can be varied according to the position of the short-circuit winding with respect to the permanent magnets of the motor rotor and the generator rotor.
