Description

电动车用无刷直流电动机定子 Brushless DC Motor Stator for Electric Vehicles

技术领域 technical field

本实用新型涉及一种直流电动机部件，尤其是电动车用无刷直流电动机定子。The utility model relates to a DC motor component, in particular to a brushless DC motor stator for an electric vehicle.

背景技术：Background technique:

目前电动车多采用两种类型的直流电动机：一种是有刷直流电动机，另一种是无刷直流电动机。这两种电动机的效率通常是在72-76％。它们采用的都是传统的整体型冲片，绕组嵌线的槽满率不高，其转子冲片(有刷直流电动机)或其定子冲片(无刷直流电动机)叠在一起，或粘黏或铆接或焊接成一个完整的铁心。采用这种传统的整体冲片，虽然性能相当不错，但是若想进一步提高它的效率，基本上是不可能的。At present, electric vehicles mostly use two types of DC motors: one is a brushed DC motor, and the other is a brushless DC motor. The efficiency of these two motors is usually in the range of 72-76%. They all use the traditional integral punching, the slot filling rate of the winding embedded wire is not high, and the rotor punching (brush DC motor) or its stator punching (brushless DC motor) are stacked together, or sticky Or riveted or welded into a complete core. Although the performance of this traditional overall punch is quite good, it is basically impossible to further improve its efficiency.

发明内容 Contents of the invention

为了克服现有技术的不足，本实用新型的目的是提供一种电动车用无刷直流电动机定子。In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a brushless DC motor stator for an electric vehicle.

本实用新型解决其技术问题所采用的技术方案是：一种电动车用无刷直流电动机定子，由多个定子齿单元拼装而成，在定子齿单元的内圆端的一侧面设置有凸圆，另一侧面开有凹孔，每一定子齿单元的凸圆嵌装于相邻定子齿单元的凹孔中拼装而成电动车用无刷直流电动机定子。The technical solution adopted by the utility model to solve the technical problem is: a brushless DC motor stator for an electric vehicle, which is assembled from a plurality of stator tooth units, and a convex circle is arranged on one side of the inner circle end of the stator tooth unit. There is a concave hole on the other side, and the convex circle of each stator tooth unit is embedded in the concave hole of the adjacent stator tooth unit to assemble the brushless DC motor stator for electric vehicles.

进一步地：定子齿单元由定子冲片按规定尺寸叠在一起，或粘黏或铆接或焊接而成。Further: the stator tooth unit is formed by stacking the stator punches according to the specified size, or sticking, riveting or welding.

更进一步地：定子齿单元的数量为24个。Furthermore: the number of stator tooth units is 24.

本实用新型结构简单、设计合理，由于定子是由定子齿单元拼装而成，在拼装前，直接在定子齿单元上绕线，导线可以排列整齐、紧凑、槽满率高，绕组端部也小，由于槽满率高、端部短，所以绕组电阻小，运行时耗损小，效率可高达82-85％.The utility model is simple in structure and reasonable in design. Since the stator is assembled by the stator tooth unit, the wires are directly wound on the stator tooth unit before assembly, and the wires can be arranged neatly and compactly, with high slot filling rate and small winding ends. , due to the high slot full rate and short end, the winding resistance is small, the loss is small during operation, and the efficiency can be as high as 82-85%.
