FIELD: physics.
SUBSTANCE: phase voltages are measured in each phase, based on which, taking into account rotor position signals, pulse duration signal for controlling angular velocity of the rotor of the motor and the clock signal, a counter emf sign signal is generated in the idle phase on the inter-commutation interval, based on which, taking into account rotor position signals, the control code sign signal, the pulse duration signal for controlling angular velocity of the rotor of the motor, interval signals and the clock signal, control signals of key elements of the pulsed power amplifier are corrected.
EFFECT: reduced torque pulsation and reduced additional power losses, which increases the operation time of device in autonomous mode.
