Abstract
PURPOSE:To obtain the smooth turning force by making it possible that the magnetic force of a position controlling electromagnet does not disturb the magnetic force of an electromagnet for the rotational drive. CONSTITUTION:The rotation of a rotor 10 is made by applying the sine wave voltage from the source of an oscillator 120 to four stator coils connected to the terminals 141-148. The rotor 10 is the focus of a position control by detecting the displacements in the directions of X and Y of the rotor 10 by the sensors 11 and 13 and controlling the voltage applied to the four position controlling coils connected to the terminals 161-168. For the Y direction, after operating the PID signals of the signals of a detector 13, for each of them as the differential signals at the second adder 112 and a subtracter 107, the inversive and the non-inversive output is selected by the analog switches 114 and 109 according to the signals from the oscillator 120, that is, to the rotating position of the rotor and is applied to the position controlling coils by adding them to the signals from the oscillator 120.
