PROBLEM TO BE SOLVED: To solve a problem of insufficient performance of a load pulsation suppressing capability due to a rough control because a voltage pattern applied to a brushless motor by dividing one revolution into twelve sections is corrected when a conventional brushless motor drive controller uses a brushless motor of a 3-phase 4-pole type. SOLUTION: When the brushless of the 3-phase 4-pole type is used, one revolution of the motor is divided into twelve sections to obtain rotation signals, the signals are linearly interpolated between adjacent signals, the interpolated signals are further N-divided, and armature windings are drive controlled by applied voltages corresponding to rotating speeds of the N-divided sections. |
