Abstract: PROBLEM TO BE SOLVED: To eliminate a torque ripple of a motor without making magnetic flux distribution of the moor have a sinusoidal waveform. SOLUTION: When a distribution of a flux density in respect of a rotation angle of a rotor has a trapezoidal waveform, as shown by a broken line in Figure, energizing currents I(θ) applied to coils corresponding to rotation angles are calculated according to the flux distribution waveform, so as to generate torque equivalent to the torque obtained, when a sinusoidal waveform current is applied to a sinusoidal waveform flux distribution. A map of the currents is formed, and a current applied to a coil is controlled according to the map and to the rotational angle detected by a rotation sensor. With such a constitution, by reducing the currents applied to the coils, corresponding to the positions where flux densities are higher tan flux densities of a sinusoidal flux distribution, the torque equivalent to the torque, obtained when the sinusoidal waveform current is applied to the sinusoidal waveform flux distribution can be generated, so that torque ripples can be eliminated easily, without having to require magnetizing a magnet to form a difficult sinusoidal flux distribution.
