Abstract

PURPOSE:To obtain both stability at low speed and revolution at high speed by mounting switching elements, which selectively connect a resistor for control and diodes in parallel in response to the speed of revolution, between the terminals of the winding of a pulse motor. CONSTITUTION:Terminals at the grounding sides of each winding L1-L4 of a pulse motor are each grounded through transistors Tr1-Tr4 for switching, controlling pulse signals are applied to input terminals 1-4 successively, each winding is excited and revolution is obtained. When revolution at low speed, a transistor Tr5 for control is conducted, a relay Sr is excited and a resistor R1 is short-circuited by the contact. Thus, diodes D1-D4 are each connected in parallel with each winding L1-L4 the step revolution of braking action by the back electromotive force of the winding is ensured. When revolution at high speed, the transistor Tr5 for control is at OFF, the resistor R1 is connected to the winding L1-L4 through the diodes and braking action is reduced.
