PURPOSE: To eliminate the effects of a transition current by connecting a control variable that is a function of a commutation angle to information that indicates the influence of a bus ripple or a transition current, regarding its variable and eliminating the effects caused by the ripple or the transition current regarding the bus from commutation angle information. CONSTITUTION: A current waveform is subjected to a distortion by a ripple or a transition current regarding supply lines L1 and L2 and a commutation controller 24 continuously gives energy to each of a stator coil winding for it. A control machine 10 controls the commutation controller 24, based on commutation angle information from a detection means 19, so that it is optimum for stable and efficient operation of a motor M/M', at the same time processes a control variable that is the function of a commutation angle, and connects the control variable to information that indicates the bus ripple or the transition current regarding the variable, thus eliminating effects due to the ripple or the transition current regarding the bus from the commutation angle information. |
