Description

全转子轮毂电机
技术领域
本发明属于电机领域，涉及一种适用于电动车使用的全转子的轮毂电机。
背景技术
目前国内市场上的电动车，绝大部分采用轮毂电机，电机带动轮毂，进而驱动车轮转动。从现有轮毂电机的结构看，主要分为高速电机和低速电机，其中又有刷电机和无刷电机之分。低速电机是一种外传子电机，其定子在中间，转子在外面，转子与轮毂结合为一体，结构简单，但没有变速机构，低速性能差，其中的有刷电机，成本较低，但重量大，工作电流大，爬坡性能差；低速无刷电机本身结构简单，零件少，但其控制器结构复杂，价格高，可靠性差。高速有刷电机的轮毂和电机是两部分，电机安装在轮毂内，通过行星齿轮减速系统带动轮毂运转，因而其爬坡性能好，技术含量高，但加工难度大，使用寿命短，一般工作效率只达到75%。可见，电机的性能限制了电动车性能的提高，需要对轮毂电机的结构进行改进才能提高电动车的性能。
发明内容
本发明的目的是提供一种小型高效，能提高电动车性能的全转子轮毂电机。
为达到上述目的，本发明的技术方案是：全转子轮毂电机，包括电机轴，通过轴承固定于电机轴上的轮毂壳体，所述轮毂壳体为电机的外转子，还包括有内转子和行星减速机构，行星减速机构的太阳轮与内转子固定连接，外齿轮与外转子固定连接，行星轮架通过离合器与电机轴连接，行星轮架固定连接至电机轴，太阳轮和外齿轮分别向相反方向旋转，与太阳轮连接的内转子及与外齿轮连接的外转子向相反方向旋转，电机没有定子，接通电源，内转子高速向车轮运动的反方向旋转，外齿轮是固定在轮毂壳体上的，因此轮毂壳体带动车轮前进。所述内转子有内转子架、磁轭和电枢组成，在内转子架一侧固定连接有换向器，电源线经电机轴内孔连接到集电环上，并通过集电环与碳刷电连接，磁轭套装在内转子架上，电枢固定在磁轭外表面上，内转子架通过内转子轴承与电机轴连接。所述离合器与行星轮架固定连接，离合器内套与电机轴固定连接。
本发明运用上述技术方案后与现有技术相比具有下列优点：
1.由于没有定子，轮毂壳体即为外转子，行星轮架与电机轴固定，因而省去了现有高速有刷电机中轮毂壳体内部的定子及电机壳，具有体积小、重量轻的优点；
2.内转子电枢固定在磁轭环外表面上，为全无槽结构，没有力矩波动；
3.设置有行星减速机构，过载能力强，换向性能好，碳刷磨损小，高效区域宽广，爬坡性能好，便于大规模工业化生产。
