发明名称 Stator structure of high-speed motor
摘要 The present invention provides, at low cost, a stator structure of a high-performance motor, which gives off lower temperature rise, strives for a more highly efficient magnetic circuit, and achieves lower power consumption at highspeed rotation, while at the same time striving to achieve a stable rotor position by preventing rotor float at highspeed rotation. In a highspeed motor comprising a stator including a stator yoke made of a soft magnetic material and coils composed of magnet wires wound on salient poles of said stator yoke; a rotor including a field magnet consisting of a permanent magnet so as to face said salient poles of said stator by way of an air gap and s shaft as the center of rotation in the center thereof; and a base plate having a housing which has two bearings for rotatably holding said rotor in the center of said stator, improvement being that said stator yoke is constituted by winding a soft magnetic steel sheet. <IMAGE>
