Resilient rotor assembly for interior permanent magnet motor

摘要

A method for manufacturing an interior magnet rotor core motor is described herein. The method includes attaching a resilient material to an inner rigid structure configured to engage a shaft associated with the motor, engaging the structure with the motor shaft, positioning the shaft and structure assembly with respect to the rotor core, and affixing the resilient material to the rotor core.
