    摘要: The speed controller includes a first pulse generator which operates in response to a motor revolution pickup head to produce a sawtooth pulse with the pulse interval being proportional to the speed of the motor and a second pulse generator for producing a series of pulses having a constant time lag relative to a certain preceding one of said sawtooth pulses. The combined pulses produce a control signal pulse series for control of the motor current.
