PURPOSE:To improve the efficiency of a motor by forming a stator core of an amorphous ferromagnetic alloy, thereby reducing an iron loss. CONSTITUTION:A rotor A is secured at a shaft 1 through a housing 2 with a magnet 3, and the shaft 1 is rotatably mounted through bearings 5 of a housing 4 at a stator B. A core 7, on which a coil 6 is wound, a drive control circuit board 8 and a magnetic detector 9 such as a Hall element are provided in the housing 4. In this case, the core 7 in the stator B is made of an amorphous ferromagnetic alloy. The housing 4 may be formed of the amorphous ferromagnetic alloy. |
