FIELD: electrical engineering.
SUBSTANCE: electric drive (1) contains: a brushless motor (2) with a permanent magnet, the motor (2) power supply bridge (3), a circuit for control of the power supply bridge (3) according to the rotor position and the phase currents (Is); the drive (1) contains a circuit (6) for detection of the opposing electromotive force (Es) induced in the stator winding zero-crossing for determination of the rotor position and a circuit (25) for indirect detection of phase currents (Is) amplitudes.
EFFECT: creation of a low-noise drive with low power consumption.
