| Abstract: | The interference fit is usually adopted between motor shaft and rotor core, but inappropriate interference magnitude will cause poor flatness of lamination, lead to poor core quality, high electromagnetic noise and large no-load current, and then influence performance indexes of motor. By experimental research and analysis, this paper presents the reasonable in- terference magnitude and technological method to ensure manufacturing quality of iron core and overall performance of motor. |
