Abstract

PURPOSE:To improve the accuracy of constant speed control, by a method wherein a speed detection signal upon rotating a rotor with a predetermined constant speed is stored in a storage means in synchronizing with the rotating phase detection signal of the rotor. CONSTITUTION:At first, the rotor 18 of a motor 11 is rotated in a constant speed with a rated rotating number under a condition that a switch 24 is opened and the switch 26 is closed. In this case, a frequency signal F is outputted from a frequency generator 13 and the phase detection signal Pp of the rotor is outputted from a phase detecting means 14. A waveform storage circuit 25 stores a speed detecting signal Vd during one turn in synchronizing with the phase detection signal Pp. When the motor 11 is rotated under a condition that it is connected to a load, the switch 26 is opened and the switch 24 is closed to operate a driving circuit 12. In this case, the waveform storage circuit 25 reads out and outputs a previously stored reference speed signal Vref in synchronizing with the phase detection signal Pp.
