PROBLEM TO BE SOLVED: To obtain a high output even by a core having small laminated thickness by magnetizing a permanent magnet extended in an axial direction in the direction corresponding to the core surface to form a magnet pole surface, and converging it to the core. SOLUTION: The magnet motor comprises a rotor formed by opposing permanent magnets 1, 2 to a core surface, a stator 3 excited by the magnets 1, 2, and a winding provided in the slot of the core 4 of the stator formed by laminating punched steel plates. The rotor formed of the magnets 1, 2 has a rotor core 6 for forming a magnetic path, and bearings 8, 9 for supporting a rotary shaft 7 are fixed to brackets 10, 11. The magnetic fluxes of the magnets 1, 2 for forming the rotor magnetize the magnets 1, 2 so axially extended as to oppose the toothed part of the core in the axial direction and the direction opposed to the core surface to form magnet pole surfaces, thereby converging the magnet poles to the core. As a result, the operating efficiency can be improved and the material of the winding part can be saved. |
