电机外置式电动滚筒效率测试方法探讨

摘要

分析了JB/T7330-2008《电动滚筒》规定的效率试验方法不适用于电机外置式电动滚筒的原因，并介绍一种合理的试验方法，通过受力分析得出电机外置式电动滚筒效率计算公式。%The paper analyzes the reason why the efficiency test method specified in JB/T7330-2008 Electric Roller is inappropriate for external-motor electric roller, introduces a reasonable test method, and figures out the efficiency calcula-tion formula of external-motor electric roller through force analysis.
