Abstract
PURPOSE:To allow a motor to generate maximum torque even in high speed rotation and to materialize high speed rotation and high speed positioning, by correcting the current phase when a rotor is rotating at high speed. CONSTITUTION:The present position of a rotor is always detected in a high resolving power by a position detecting means 5. A comparison is made between the present position (b) and an target position command 9 by a comparison means 7, and based on the deviation amount (c) the electric angle amount (e) against coils 3 and 4 is operated by an operational electric angle operating means 8. By supplying the electric angle amount (e) as the operating amount to a driving means 10 through a function generating means 9, the phase of synthetic magnetomotive force of coils 3 and 4 is controlled in accordance with the deviation between the present position (b) and the target position (a). The rotating speed (g) of a rotor 1 is detected from the present position (b) by a speed signal generating means 12 and a corrected amount CP against the electric angle amount (e) is outputted by a corrected amount generating means 13.
