<p><P>PROBLEM TO BE SOLVED: To provide a rotating electrical machine that can maintain circumferential pitches at the tip of a tooth in a highly accurate manner using small coupling members in order to constrain cogging due to the variation in the pitch and reduce a torque ripple as well as improve an efficiency of coil winding. <P>SOLUTION: A rotating electrical machine comprises a stator core 6 having a plurality of teeth 13 and a coupling member 16 for coupling the plurality of teeth 13. The rotating electrical machine rotatably drives a rotator arranged in the inner periphery of a stator with a coil wound therearound by switching electrical current for the coil of the stator and generating a rotating magnetic field. The stator core 6 closely arranges one end of the inner periphery of the plurality of teeth 13. Each of the plurality of teeth 13 has a slope 15 such that spaces 14 between the one ends of the inner periphery of the plurality of teeth 13 spread in the direction of the external diameter of the one ends of the inner periphery of the teeth 13. The coupling member 16 contacts with the slope 15 and is integrated with the plurality of teeth 13 in the circumferential direction. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
