摘　　要：根据毕奥-萨伐尔定律和安培定律推导出定子端部绕组磁感应强度和电磁力密度的计算公式。并通过建立端部绕组的UG三维模型,得到了线圈端部中心线的各分段点的坐标,再利用Excel VBA编写程序,计算得到了端部绕组磁感应强度和电磁力密度。最后,分析了端部电磁力密度的周期性、规律性和峰值分布情况,为合理设计端部结构、支架和正确设定端箍绑扎位置提供技术支撑。Formulas to calculate the magnetic induction intensity and electromagnetic force density of the stator end winding is deduced according to the Biot Savart’s law and Ampere’s law. And then, coordinates of each section point of the coil end center-line are obtained through establishing the UG 3 D model of the end winding while the Excel VBA write program is applied to calculate the magnetic induction intensity and electromagnetic force density of the stator end winding. Finally, analysis on the periodicity, regularity and peak distribution of the electromagnetic force density of the end winding is performed, to make the rational design of the end construction and support as well as the suitable position to set up bracket or end hoop bindings become possible.
