PURPOSE: A permanent magnet motor and a fluid super-charging system thereof are provided to accurately detect the rotation speed and location of a rotor by combining a hole sensor installed in the casing part of a housing with a magnet mounted on a rotor rotation shaft. CONSTITUTION: A rotor(150) comprises a rotary shaft(151) supported inside a housing(110) and a permanent magnet(153) mounted along the columnar direction of the rotary shaft. A stator(113) comprises a core part(112) functioning the permanent magnet and a winding part(111). At least two bearings are arranged in the front side and the rear side of the rotor. A magnet(182) is installed in the rear side end part of the rotor rotary shaft which is not corresponding to the winding part of the stator. A hole sensor(181) is installed in the housing of a region corresponding to the magnet. |
