PURPOSE:To intend to reduce fluid loss and solid loss accompanied to revolution, by impressing driving pulse of same phase to driving coil at least twice. CONSTITUTION:The pulse motor is composed of permanent magnet rotor 201, stators 202-205, driving coils 206-207, stopped stable points 208-211 and magnetic poles 212-215, and impresses alternative driving pulse of constant pulse width to the driving coils 206, 207. At this time, driving pulse of same phase is impressed at least two times. Thus, since revolution angle of 1 step is reduced and kinetic energy which is needed in revolution is reduced, angle velocity which has same moment of inertia is recduced and fluid loss and solid loss are reduced. |
