Abstract
This paper presents a new manufacturing and estimating method of motors to achieve low torque ripple. We have developed the manufacturing method to increase the coil fill factor of motors 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 a new evaluation method which predicts torque ripple more precisely than the evaluation method from the circularity of inner core has been established.
