A method for operating a brushless motor, wherein the controllers with an open control loop and the closed control loop to use different commutation method

摘要

A motor control unit is connected both to a control / regulation (40) with an open control loop, as well as with a control / regulation (42) provided with a closed control loop. The control / regulation (40, 42) with an open control loop and with a closed control loop commutation signals lead back to the gate - drivers (32) for an inverter (30), wherein the commutation signals in the case of the control / regulation with an open control loop sinusoidal signals used and in the case of the control / regulation with a closed control loop to use a six-order commutation.
