摘要： To provide a toroidal core type actuator having a stator unit which is increased in winding density, is improved in methods of the terminal handling after winding, the positioning of the stator after winding, and the fixing of the same, and is excellent in working properties. A toroidal core type actuator having a stator and a rotor is provided, the stator having winding applied to a hollow cylindrical core composed of soft magnetic material, the rotor including a permanent magnet having north poles and south poles alternately arranged in total of m along the circumferential direction thereof, the rotor being rotatably arranged in the core of the stator via a minute air gap, wherein m of phase separators composed of non-magnetic material are arranged on the peripheral surface of the hollow cylindrical core so as to be separated from each other by 360°/m and the winding is applied to winding regions separated from each other by the phase separators.
