Title: Speed controller for motor
Inventor: GOTOU MAKOTO
IPC: H02P29/00
Filed: 1981-11-24
Abstract: PURPOSE:To improve the transient responding characteristic of a motor by controlling the motor based on the rotating speed of the motor, the speed error corresponding to the rotary phase, the phase and the phase error. CONSTITUTION:A pulse generator 12 generates a pulse signal of frequency varying in response to the rotation of a motor 11, and a pulse generator 14 generates a pulse signal having frequency lower than the pulse signal. A speed detector 13 outputs a digital signal corresponding to the instantaneous rotating speed of the motor 11, and a phase difference detector 16 detects the phase difference between the pulse signal from the pulse generator 14 and the reference signal from a reference signal generator 15. An arithmetic unit 17 controls a power supply unit 18 based on the digital output of the detector 13 and the digital output of the detector 16, thereby improving the transient responding characteristic of the motor at the starting time of the motor 11.
