Abstract
A positioning current is supplied to each phase winding of a stator employed in an electric motor, thereby rotating a rotator in the motor to a predetermined reference position with the use of magnetic force created by the positioning current. Thereafter, a polarizing current is supplied to each phase winding of the stator, thereby polarizing permanent magnets incorporated in the rotator.
