ABSTRACT:
A speed control circuit for a series motor is disclosed which keeps the rotational speed of a motor constant by detecting the slight change of an electromotive force caused by the change of the load motor. A gate signal from a trigger signal generating element is provided to the base of a thyristor connected in series with the series motor. The gate signal is controlled by a control circuit.
