PROBLEM TO BE SOLVED: To provide a rotor of variable magnetic flux magnet capable of realizing demagnetization at high-speed rotation with a simple configuration. SOLUTION: A rotating or direct action magnetic flux shorting member 7 is stored in a flux barrier (slit) 3 for reducing a leaked magnetic flux, that is provided between permanent magnets 5 and 5 of the rotor core of IPM. It realizes an IPM rotor composed of a simple and compact demagnetization mechanism. COPYRIGHT: (C)2004,JPO&NCIPI
