<p><P>PROBLEM TO BE SOLVED: To provide a dynamo electric machine which can reduce torque ripple even if a slight level difference exists in the profile of inside diameter of a stator core formed by arranging coupled split cores split for respective magnetic poles annularly. <P>SOLUTION: A plurality of laminates made by laminating coupled split core members which are formed by punching a steel plate and arranged circularly are laminated while turning mutually by a predetermined angle to constitute a stator core. Torque ripple components of a stator core are reduced as a whole by canceling torque ripple components caused by asymmetry in profile of respective laminates. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
