Publication number: 20150340913Abstract: A low-cog permanent magnet motor includes a stator and a rotor. The stator includes a plurality of bobbins. The bobbins are arranged in a radial pattern. Each of the bobbins forms a pole shoe, and the pole shoes are arranged in a ring shape. The rotor includes an outer sleeve which encloses the stator and includes an even number of permanent magnets attached to an inner wall of the outer sleeve. The permanent magnets are arranged in a ring shape. Each of the pole shoes includes an outer curved surface facing an inner wall of the outer sleeve and includes an inner arc surface opposite to the outer arc surface, and a radius of the outer arc surface is smaller than a radius of the inner arc surface. A cogging torque is reduced by changing a shape of the pole shoe.Type: ApplicationFiled: May 21, 2015Publication date: November 26, 2015Inventors: Yuan-Hung CHO, Chien-Ho LEE, Chao-Hsing KANG, Tsung-Yin LEE
