Abstract: PROBLEM TO BE SOLVED: To prevent demagnetization caused by a low temperature by supplying high-frequency current to a stator coil for generation of a high-frequency field and heating of a permanent magnet by core loss generated at a core part when the temperature of a permanent magnet in a permanent magnet motor drops to a prescribed value or lower. SOLUTION: A stator 12 includes a core 14 which has comb-shaped magnetic poles inside a cylinder, and a coil 16 stored between the poles. A rotor 18 is constituted of a cylindrical rotor core 20 and a permanent magnet 22 at a prescribed interval over its periphery. An inverter 26 converts direct current into alternating current whose frequency and amplitude are prescribed ones, so that power is supplied to a drive motor 24. A controller 30 controls the inverter 26 with a signal from a temperature detecting part 40 of an operation part 32 and the drive motor 24. If detected temperature is judged to be such a temperature as the permanent magnet 22 conducts demagnetizing, high-frequency current is supplied to the stator coil 16, and the permanent magnet 22 is heated by core loss generated at the core part.  It is thus possible to prevent malfunction caused by permanent magnet demagnetization.
