PROBLEM TO BE SOLVED: To provide a magnetic flux variable motor with a kind of sintered magnet, capable of increasing a maximum energy product of NdFeB sintered magnet and making residual magnetic flux density variable, which has never been achieved by a conventional technology.SOLUTION: The sintered magnet motor of the present invention includes a rotor, a stator, and a coil, and the rotor is formed with a sintered magnet. The sintered magnet motor controls the residual magnetic flux density of the sintered magnet using a magnetic field developed by a coil current. |
