PROBLEM TO BE SOLVED: To provide a motor structure that can reduce the occurrence of cogging torque and torque ripples. SOLUTION: In the motor structure accommodating a cylindrical stator core 2a inside a cylindrical casing 1, a gap t is provided between the outside circumference of the stator core 2a and the inside circumference of the casing 1, and the stator core 2a is accommodated inside the casing 1 being prevented from rotating. Thus, the stator core 2a is self aligned by a rotor 3, which makes it possible to reduce the occurrence of the cogging torque and torque ripples. COPYRIGHT: (C)2008,JPO&INPIT |
