Technical Problem
[0003]基于此，本申请提供一种转子冲片、转子总成和电机，以改善现有技术中当转子冲片上可开槽的区域有限时，尤其是当一对磁钢槽之间的区域不适合开槽时，电磁优化方案难以实现的问题
Benefits of technology
[0014]本申请通过将第一开槽设置在一对第一磁钢槽相互靠近一端的径向内侧，可以减少电磁泄露，且提升电磁力波正弦度；且将第二开槽设置在一对第二磁钢槽相互靠近一端的径向内侧，可以疏导电磁力线流向及分布，避免电磁力波形产生畸变，减少高阶次谐波分量；而本申请中的第一开槽无需设置在一对第一磁钢槽相互靠近的一端之间，且第二开槽无需设置在一对第二磁钢槽相互靠近的一端之间，因此本申请可以在转子冲片上可开槽的区域有限时，尤其是当一对磁钢槽之间的区域不适合开槽时有效地实现转子冲片电磁方案的优化。

Abstract
The application relates to a rotor lamination, a rotor assembly and a motor. The rotor lamination comprises a rotor lamination body, and a plurality of groove units are arranged on the rotor lamination body; the groove units comprise first magnetic steel grooves, second magnetic steel grooves, first grooves and second grooves; one end of the first magnetic steel grooves is arranged on the inner side in a radial direction and the other end is arranged on the outer side in a radial direction; one end of the second magnetic steel grooves is arranged on the inner side in a radial direction and the other end is arranged on the outer side in a radial direction; the first grooves are arranged in pairs on the inner side in a radial direction of the one end of the first magnetic steel grooves; and the second grooves are arranged in pairs on the inner side in a radial direction of the one end of the second magnetic steel grooves. The application can effectively realize optimization of an electromagnetic scheme of the rotor lamination when the slottable area of the rotor lamination is limited, especially when the area between the first magnetic steel grooves is not suitable for being slotted.
