The invention relates to an apparatus and method for controlling the current flow of at least one phase winding of a switched reluctance motor during at least one dwell period of the motor, wherein the dwell period starts with a turn-on angle of the motor and ends with the turn-off angle of the motor, wherein the dwell period is divided in a first subinterval comprising a first reference current, a second subinterval comprising a second reference current and a third subinterval comprising a third reference current, wherein the flow of the first reference current is controlled based on at least one motor-efficiency parameter which depends on the efficiency of the motor, wherein the flow of the second reference current is controlled based on at least one torque-parameter which depends on the torque of the motor to control the torque production of the motor, and/or wherein the flow of the third reference current is controlled based on at least one noise-and/or-vibration-parameter which depends on an electromagnetic force produced by the motor to reduce noise and/or vibration of the motor.
