Abstract

PURPOSE:To improve the decrease in an output torque in a low speed rotation range by increasing the pulse width of a pulse current for exciting a coil when a rotating speed is decelerated. CONSTITUTION:A counter 57 for deciding the pulse width of pulse current by counting the prescribed clock signals is provided. A counted value is selected from a signal width counter value table by a controller 51, and a set signal K is written in the counter 57. Thus, the counted value of the counter 57 is increased in response to the decrease in the rotating speed to increase the exciting period of the coil by the exciting current, thereby holding the similar output torque to that at normal rotation time even in a low speed rotation range.
