description The present invention relates to a variable-flux motor comprising: a stator having stator coils; and a rotor disposed to be rotatable with respect to the stator with an air gap interposed therebetween, wherein the rotor comprises: a rotor core; a fixed magnet disposed along the radial direction of the rotor core, and of which one end portion is disposed adjacently to the air gap; and a variable magnet disposed inside the fixed magnet along the radial direction of the rotor core, and the variable magnet is formed such that a magnetic flux thereof varies when a preset current is applied to the stator coils. Therefore, use of an expensive permanent magnet can be excluded.
