发明名称 Claw pole type motor and pump
摘要 <p>A claw pole type motor includes a rotor having a magnet arranged on an outer circumferential surface thereof and a stator including an annular iron core and an annular coil received within the iron core. The iron core includes a yoke portion opened in an inner circumferential surface opposite to the rotor, a plurality of upper claw-shaped magnetic poles and a plurality of lower claw-shaped magnetic poles which are arranged along an inner circumferential surface of the annular coil. The upper/lower claw-shaped magnetic poles are curved to extend axially downwardly/upwardly from an upper/lower inner edge of the yoke portion, respectively. The upper and the low claw-shaped magnetic poles are alternately arranged along a circumferential direction of the iron core. The yoke portion has cutout portions formed in non-magnetic path regions which do not include magnetic paths through which magnetic flux flows between neighboring claw-shaped magnetic poles across the annular coil. </p>
