Abstract
Disclosed therein is a method of operating a variable magnetic flux motor. The method of operating the variable magnetic flux motor, which includes a rotor and a stator located inside the rotor, the rotor including first magnets and second magnets having a coercive force weaker than that of the first magnets, includes: a first step of operating the motor in an initially magnetized state of the second magnets; and a second step of operating the motor in an inversedly magnetized state of the second magnets by applying a magnetomotive force to the second magnets in the opposite direction to the magnetization direction of the second magnets.
