Abstract
A perspective electric drive based on a dual-fed switched reluctance drive with two multiphase windings on the stator and a toothed rotor has been considered. The electric drive can be used in spacecrafts for antenna and solar panels rotation systems. The possibilities of the electric drive control to achieve a high smoothness of rotation at low speed have been studied. The possible control options with different combinations of frequencies and amplitudes of supply voltages of two windings were shown.

Summary
To ensure the smooth rotation of the rotor, the motor should be powered by highfrequency voltage. In this case the speed will be high as well. 2. Problem solution It is proposed to use an alternative type of the electric motor which has two multi-phase windings instead of one winding on the stator (as in a conventional motor) (figure 1). Problem solution It is proposed to use an alternative type of the electric motor which has two multi-phase windings instead of one winding on the stator (as in a conventional motor) (figure 1) Each of these windings is powered by its own multi-phase voltage and creates two electromagnetic fields that rotate towards each other and form a common field. The drive control system (Figure 4) solves three tasks: 1) adjusting the angle of rotation r in accordance with the desired law of motion; 2) speed control r . 3) adjusting the load angle in the range / 2 M / 2
