Abstract
PURPOSE: To provide substantially same load characteristics of a motor as that controlled in phase only with a speed control loop control circuit by employing a constant pulse duration generating circuit.
CONSTITUTION: A signal waveform proportional to the rotating speed of a motor 1 from a frequency generator 2 is shaped by a waveform shaping circuit 3. A constant pulse duration generating circuit 5 retains "1" level with a trigger signal of the fall of an output signal from the circuit 3 while counting N pieces of output pulses of a standard frequency signal generating circuit 4, and becomes "0" level after completing the counting of N pieces of the pulses. A pulse synthesizing circuit 6 synthesizes the output pulse of the circuit 5 and the output pulse of the circuit 3 and supplies the synthesized pulse to a motor drive circuit 9.
