Abstract
PURPOSE: To facilitate to determine an operation point in the design of the circuit by a method wherein one set of driving circuit is operated with respect to one set of control coil when a consuming electric power is low while two sets of the driving circuits are operated when the consuming electric power is large.
CONSTITUTION: An electric current, flowed through the control coils 20, 21 by circuits 9, 10 or the circuits 11, 12 through a signal 24 from the circuit 15, is controlled by a method wherein an operation such as adding or the like and a signal processing such as amplifying or the like for either one or both of a velocity signal 13 or a position signal 14 are effected in a signal processing circuit 15 to control the bias points of the driving circuits 9W12 through the circuits of bias control circuits 16W19. When the signal is small, the circuit 10 is operated mainly while the circuits 9, 10 are operated simultaneously when the signal is large, therefore, a wide operating range within which a current from the micro current to the large current may be flowed is not necessitated for one set of the driving circuit, and the determination of the operation point may be facilitated.
