Description
This paper presents a new manufacturing and estimating method of motor for low torque ripple. We have developed the manufacturing method to increase the coil fill factor of the motor by using separate core. That caused high efficiency of motor, however, the core precision tends to be bad in the case of separate core and that causes large torque ripple. In this paper we declared the relationship between core precision and torque ripple. And the new evaluation method which predicts torque ripple more precisely than the evaluation method from the circularity of inner core has been established. By using this method, the point of core which causes large torque ripple can be turn out.
