PURPOSE:To provide a motor controller for rotating a motor smoothly. CONSTITUTION:A comparing means 30f receives a detection signal S representing the rotational state of a motor 5 through an A/D converting means 30b and determines a correction amount based on actual period and phase. A period setting means 30e corrects set period and set phase and then creates a sine wave having period and phase defined by sine wave data stored in a sine wave data region 30g thus producing a sine wave driving signal D through a D/A converting circuit 30c. The motor is rotated smoothly through the waveform effect of the driving signal. |
