PURPOSE:To extend and diversify the function of a pulse motor by forming a plurality of pulse motors on the same shaft at different step angles. CONSTITUTION:Two pulse motors 1, 2 are secured axially adjacently, and the both motor shafts (output shafts) 3 are composed of the same shaft as a common shaft rotating integrally. The motors 1, 2 have different step angles, and are composed of stators 6 having a plurality of tooth forms 4 for forming a magnetic path and a plurality of exciting coils 5, and rotors 7 having multipolarized magnets. Thus, the motors 1, 2 are excited and operated independently at special step angles (theta1, theta2) by supplying a drive current in the prescribed sequence to the exciting phases. |
