Abstract

PURPOSE:To obtain sufficient torque while lowering power consumption by mounting a switching transistor, which detects the output voltage of a constant- current circuit while operating output currents under a stationary state so as to decrease the currents more than a transient state. CONSTITUTION:When exciting currents are supplied to an exciting coil A, the output voltage V1 of the constant-current circuit SC1' slowly drops in response to the reaching of the back electromotive force of the coil to ''0'' and the approaching of the exciting currents to a stationary value from a value E-VZ2 of the initial state. When the output voltage V1 reaches X, a transistor Q5 for switching is brought to an on state, and the emitter currents of a transistor Q6 for control are lowered. When the exciting currents are brought to a stationary state, the output voltage V1 reaches a stationary value Y.
