FIELD: electrical engineering.
SUBSTANCE: brushless DC motor comprises a stator with a winding, a rotor with a winding. Rotor and stator control units are connected by their inputs to an external power source. To achieve the technical result, a radiation emitter and a receiver are introduced, which ensure contactless transfer of electric energy by the emitter to the rotor winding of the electric motor. Input of the radiator is connected to the output of the rotor adjustment unit, the output of the radiation receiver is connected to the rotor winding. Input of the rotor position feedback unit is contactlessly connected to the rotor winding, and the output of the rotor position feedback unit is connected to the control input of the electronic stator switching unit, the output of which is connected to the stator winding. Input of the stator switching electronic unit is connected to the output of the stator adjustment unit.
EFFECT: higher reliability and wider field of application.
