Abstract
PURPOSE: To decrease a speed fluctuation for a load fluctuation by making a speed variable continuously between a determined speed of a positive rotation direction and a determined speed of a reverse rotation direction.
CONSTITUTION: A rectifier bridge consisting of diodes D101,D102 and thyristors CR103,CR104, a series connection circuit of an alternating current power source Vac10 to be connected to the former circuit and an armature A1 of a commutator motor, a field F of the motor, a deviation voltage generating circuit consisting of a speed detector TG etc. generating a deviation voltage varying a polarity and an absolute value relating with a required rotation direction and a speed of the motor and an ingnition phase control circuit 500 controlling an ignition angle of a thyristor CR 104 relating with an absolute value of a deviation voltage when a deviation voltage is positive and controlling an ignition angle of a thyristor CR 103 relating with an absolute value of a deviation voltage when a deviation voltage is negative are provided. This circuit constitution makes a change over switch customary necessitated not necessary, a change over of a positive rotation and a reverse rotation is performed simply and smoothly, as a field current circulate through diodes even in case of thyristors being non-conductive a pulsation is decreased and a field voltage drop becomes small equivalently.
