A method for calculating a driving current waveform for minimizing a torque pulsation in brushless motors having a difference in construction of a magnetic circuit which are driven on such driving current. The method calculates the driving current waveform so as to reduce the sum of currents carried to coils of each phase of the brushless motor to zero, whereby a necessity to keep a common junction of the coils of each phase at a low impedance can be avoided and the circuit configuration simplified.
