Abstract

PURPOSE: To control the motor at required speed, by making a feed-back of the pulse with a width of constant time interval, on the basis of output of the incremental encoder.
CONSTITUTION: A rotational speed of the motor, as a position signal at every constant degree of angle by an incremental encoder 3, is inputted to the countdown input terminal of a counter 16, with a speed set signal gradually counted down. With a value of the counter 16 becoming 0, a carry output pulse, having a time interval inversely proportional to the rotational speed of the motor 4, is outputted from a signal line 20, with the speed set signal of a memory 15 newly set to the counter 16, simultaneously with said carry output pulse triggering to output a speed pulse, with a constant time width, from a monostable multivibrator 17. With this speed pulse received, a switching driver 18v feeds a negative voltage, for the speed pulse when outputted to a oneshot 17, and a positive voltage, for the pulse when not outputted, to the motor.
