FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and can be used in the follow-up motors. Electric drive actuator unit contains a multipolar rotor and a geared stator, on which the synchronous motor and the generator windings are located, made with a toothed pitch, as well as the position sensor elements, made, for example, in the form of Hall sensors, the actuator unit stator contains two magnetic circuits, on one of which the motor winding is arranged, and on the other are the generator winding and the position sensor elements, wherein said windings occupy all slots of their magnetic circuit, and the position sensor elements are placed on the teeth of one of the phase groups of the corresponding generator phase and are arranged relative to each other at an angle of ϕ radians, where for the odd number and
for the actuator unit phases even number, at that, the position sensor may be provided with a second set of elements disposed on the teeth of the generator windings diametrically located groups.
EFFECT: technical result consists in improving of the actuator unit and the drive in general technical characteristics, namely, in increasing the motor torque and the generator steepness; compensation of even harmonics in the motor stator current, in the generator output voltage and in the position sensor output signals; improvement of the current shape in the motor; reducing the motor torque and the speed sensor output voltage ripple, as well as in reducing the mutual inductive connection between the motor and the generator windings.
