Filed: 2010-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent dropping and fluctuation of a drive current for a motor as well as a torque based on a deviation between an end timing of trigger electrification and a control cycle of PWM control.SOLUTION: A calculation part 41a corrects the time of trigger electrification so that the drive current of an SR motor 1 after the trigger electrification agrees with a target current at the timing of control cycle of PWM control. When shifting to the PWM control after the trigger electrification time expires, the drive current of the SR motor 1 does not fail to become a target current at the timing of control cycle (carrier cycle) of PWM control. Thus, deviation is prevented between the target current and the drive current at the time when switched to the PWM control.
