<P>PROBLEM TO BE SOLVED: To provide a motor and a stator of the motor suppressible torque ripple. <P>SOLUTION: A motor 1 has a rotor 7 and a stator 3 surrounding the rotor 7. In the stator 3, a facing curved surface opposite to the rotor 7 continues along with a circumferential direction of the rotor 7, and the surface comprises two curved surfaces (a first surface 46 and a second surface 47) each having mutually different curvature radius. <P>COPYRIGHT: (C)2012,JPO&INPIT |
