<P>PROBLEM TO BE SOLVED: To reduce deviation of a magnetic flux amount due to shapes of teeth compared to a conventional case. <P>SOLUTION: A stator core 10 includes: a cylindrical yoke 12; and teeth 14 which are arranged in a circumferential direction on an inner peripheral face of the yoke 12 and receive magnetic flux from a rotor 11 of a rotary electric machine. The tooth 14 includes a trapezoid tooth 16 whose cross-sectional shape vertical to a central axis of the yoke 12 is trapezoid and a modified tooth 18 whose tip 19 has the same shape as that of the trapezoid tooth 16 and whose base 21 from the tip 19 to the yoke 12 has the shape different from the trapezoid tooth 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
