具体实施方式

为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和实施方式对本发明作进一步的详细说明。
请参考图1至图13，本发明公开的一种盘式电机包括定子组件100和转子组件200，其中，定子组件100包括电机端盖101、固定心轴102和分瓣铁芯103，分瓣铁芯103设置在绕线骨架104中，并位于电机端盖101和固定心轴102之间；电机端盖101与绕线骨架104的外周形成第一腔体1015；绕线骨架104的内周与固定心轴102之间形成第二腔体1016；绕线骨架104的绕 组之间具有连通第一腔体1015和第二腔体1016的间隙；电机端盖101上设置有向第一腔体1015喷射油的喷油口1017以及排出第一腔体1015中的油的出油口1018；固定心轴102上设置有连通第二腔体1016的导油孔。

导油孔的作用是对固定心轴102进行散热，固定心轴102的中部设置有连接转轴的轴承109，导油孔包括靠近喷油口1017的第一导油孔1021和靠近出油口1018的第二导油孔1022，第一导油孔1021和第二导油孔1022均连通轴承109与第二腔体1016。靠近喷油口1017的第一导油孔1021进入的油充分与轴承109、转轴以及固定心轴102进行散热，并通过第二导油孔1022流入第二腔体1016中，从而使得油持续与轴承109、转轴以及固定心轴102接触，从而提高了轴承109、转轴以及固定心轴102的散热效率，相当于提高盘式电机的散热效率。
本发明的定子组件100还包括第一固定架105和第二固定架106，其中，固定心轴102位于电子端盖中部；绕线骨架104上设置有多个呈环状布置的缠绕架，每相邻的两个缠绕架之间形成安装套组107的分瓣槽；每个缠绕架设置有一个安装槽，每个安装槽设置一个分瓣铁芯103，且分瓣铁芯103固定于安装槽时，分瓣铁芯103的第一端和分瓣铁芯103的第二端均露出安装槽；第一固定架105固定在电机端盖101的第一端，第一固定架105的中部固定在固定心轴102的第一端，第一固定架105的部分与分瓣铁芯103的第一端露出安装槽的部分抵接以限制分瓣铁芯103的圆周方向旋转；第二固定架106固定在电机端盖101的第二端，第二固定架106的中部固定在固定心轴102的第二端，第二固定架106的部分与分瓣铁芯103第二端露出安装槽的部分抵接以限制分瓣铁芯103的圆周方向旋转，且绕线骨架104位于第二固定架106和第一固定 架105之间。

采用本发明的转子组件200，一方面通过相互配合的定位凸起和定位凹槽实现转子铁芯202的第一端面与转子盘201的第二端面的圆周方向限位固定，另一方面通过第二紧固件204实现了转子铁芯202的第一端面与转子盘201的第二端面的轴向方向限位固定，从而提高了转子组件200轴向连接的稳定性延长了盘式电机的电机效率。
转子铁芯202经硅钢片冲压或者卷绕加工而成，例如，由硅钢片、非晶合金或者整体模压的磁性粉末冶金加工而成。优选的，采用卷绕加工而成，采用卷绕的加工方式，铁耗及涡流损耗小，因此转子组件200的损耗小、温升低、盘式电机效率更高。磁钢203的径向截面为矩形结构、梯形结构、扇形结构等等，结构。
上述定位凹槽和定位凸起的实现转子盘201和转子铁芯202的圆周方向限位固定，其中，转子盘201上只设置有定位凹槽，而转子铁芯202上只设置有定位凸起；或者转子盘201上只设置有定位凸起，而转子铁芯202上只设置有定位凹槽；或者转子盘201上均设置有定位凹槽和定位凸起，而转子铁芯202上均设置有定位凹槽和定位凸起。本发明其中一个实施例中，转子盘201上均设置有定位凹槽和定位凸起，而转子铁芯202上均设置有定位凹槽和定位凸起。具体的，定位凹槽包括第一定位凹槽2011和第二定位凹槽2022，定位凸 起包括第一定位凸起2012和第二定位凸起2023，其中，多个第一定位凹槽2011设置在转子盘201的第一端面，每相邻的两个第一定位凹槽2011之间形成一个第一定位凸起2012；多个第二定位凸起2023设置在转子铁芯202的第一端面，每相邻的两个第二定位凹槽2022之间形成一个第二定位凸起2023；第一定位凹槽2011与第二定位凸起2023相配合，第一定位凸起2012与第二定位凹槽2022相配合。
转子盘201采用第一定位凸起2012和第一定位凹槽2011间隔布置的方式在实现转子盘201和转子铁芯202圆周方向限位固定的功能的基础上，还能够减少转子盘201的厚度。转子铁芯202采用第二定位凹槽2022和第二定位凸起2023间隔布置的方式在实现转子铁芯202和转子盘201圆周方向限位固定的功能的基础上，还能够减少转子铁芯202的厚度。
本发明的第二紧固件204设置在第一定位凸起2012的位置，或者设置在第一定位凹槽2011的位置，或者第一定位凸起2012和第一定位凹槽2011的位置均设置有第二紧固件204。可选的，第一定位凹槽2011上设置有第五安装孔，第二定位凸起2023设置有第六安装孔，第五安装孔和第六安装孔同轴设置，并用于安装第二紧固件204。
在转子铁芯202中，一个钢槽2021与第二定位凸起2023相对应，或者一钢槽2021与第二定位凹槽2022相对应，或者一个钢槽2021与一个第二定位凸起2023和一个第二定位凹槽2022相对应，或者一个钢槽2021与一个第二定位凸起2023和两个第二定位凹槽2022相对应，或者一个钢槽2021与两个第二定位凸起2023和一个第二定位凹槽2022相对应。可选的，每个钢槽2021与第二定位凹槽2022相对应，钢槽2021的中心面与第二定位凹槽2022中心面重合。
上述钢槽2021为燕尾槽，能够进一步提高磁钢与钢槽2021的连接力。
上述转子组件200的数量为一个或两个，当为一个时，设置在定子组件100的一端，当为两个时，其中一个转子组件20设置在定子组件100的一端，另一个设置在定子组件100的另一端。
