不对称气隙小功率单相无刷直流电动机的定位力矩分析与计算

Calculation and Analysis for the Cogging Torque of Single-phase Low Power BLDCM with Asymmetrical Air Gaps

针对不对称气隙小功率单相永磁无刷直流电动机定位力矩的计算问题建立了两种数学模型 ,用解析的方法对定位力矩进行了定性的分析 ,用有限元方法进行了实例计算 。

In this paper,two different mathematics models are established,aiming at the calculation problem for the cogging torque of single-phase low power BLDCM with asymmetrical air gaps and the cogging torque is analyzed qualitatively using analytical method.The instance is calculated using the method of finite-element,which is proofed by the test.
