<P>PROBLEM TO BE SOLVED: To provide a motor controller which can stably drive a synchronous motor which does not have a position sensor with high efficiency using simple control. <P>SOLUTION: A reactive current is obtained from a motor current and rotational phase, and error voltage is obtained from the reactive current and the reactive current command, to compensate for the F/f characteristics of a motor. <P>COPYRIGHT: (C)2003,JPO |
