RETENTION SLEEVE AND BALANCE STRATEGY FOR A HIGH SPEED PERMANENT MAGNET ROTOR

A method for reducing stress concentration on a rotor sleeve during balance cutting comprising: providing an axial protrusion to an outer diameter of a first end cap and a second end cap of a rotor assembly; and radially cutting at least one of the sleeve or the axial protrusion to balance the rotor assembly. 种用于在平衡切割期间减小转子套筒上的应力集中的方法，该方法包括：向转子组件的第端盖和第二端盖的外径提供轴向突起；和径向切割套筒或轴向突起中的至少个以平衡转子组件。
