Title: Speed controller for motor
Inventor: TSUCHIYAMA YOSHIRO
IPC: H02P29/00
Filed: 1986-06-09
Abstract: PURPOSE:To accurately control the speed of a motor by resetting a timer counter by a rotating position detection signal obtained by the rotation of the motor. CONSTITUTION:A microcomputer 1 filter-calculates for stably compensating a control system by a speed error between a speed signal and a speed reference value, and writes a motor drive command value in a latch 3. This filter calculation is started by a timer interrupt request signal output from a timer counter 2. The output of the latch 3 is transferred to a latch 4 by the timer interrupt request signal. The output of the latch 4 is fed through a D/A converter 5 to a motor driver 6. The counter 2 is reset by a rotating phase detection signal by a rotating phase detector 9 attached to a motor 7. Thus, the counted state of the counter 2 is synchronized with the rotating phase of the motor 7.
