PURPOSE:To realize an inexpensive motor controller without troublesome handling. CONSTITUTION:A resolver 8 is directly coupled with an output axis 7 so that a controller 5 receives an angle signal corresponding to the rotational angle. In the controller 5, a microcomputer calculates a magnetic polar position of a rotor in a motor 1 by using the rotation angel of the output axis 7 on the basis of a previously set calculation formula so that a current with an appropriate phase is provided to the motor 1. |
