ABSTRACT:
A pulse motor is improved in its stability at the time of low revolution while maintaining the possibility of high revolution. Between the terminals of pulse motor windings there are parallel-connected current control means. The braking effect of said current control means is controlled depending upon the revolution of the pulse motor so as to stabilize the revolution at a low speed. It assures also a high speed revolution when desired. This arrangement of the invention enables to provide a pulse motor which is small in size and low in cost. When the present invention is embodied in a driving system for a carriage of printing head in a printer, all the performances required therefor can be attained.
