The invention provides a disc type motor, a power assembly and an electric vehicle, the disc type motor comprises a stator and a rotor, and the rotor and the stator are adjacently arranged along the axial direction. Alternating magnetic flux generated by the stator interacts with permanent magnetic flux generated by the rotor, so that the rotor rotates relative to the stator. The stator comprises a plurality of magnetic cores which are arranged at intervals in the circumferential direction of the stator, and a groove is formed between every two adjacent magnetic cores. Each magnetic core comprises two radial end faces and two circumferential end faces, the two radial end faces are oppositely arranged in the radial direction of the stator, and the two circumferential end faces are oppositely arranged in the circumferential direction of the stator. At least one circumferential end face of the at least one magnetic core is radially inclined with respect to the stator. The slots between the two adjacent magnetic cores form the skewed slots, the magnetic cores of the stator have a certain magnetism gathering effect, the torque fluctuation of the stator is small, the output torque of the disc type motor can be improved, and the power of the electric vehicle can be improved.
本申请提供了一种盘式电机、动力总成及电动车,该盘式电机包括定子和转子,转子和定子沿轴向相邻排列。定子产生的交变磁通与转子产生的永磁磁通之间相互作用,使得转子相对定子转动。定子包括多个磁芯,多个磁芯沿定子周向间隔排列,相邻的磁芯之间形成槽。每个磁芯包括两个径向端面和两个周向端面,两个径向端面沿定子径向相对排布,两个周向端面沿定子周向相对排布。至少一个磁芯的至少一个周向端面相对于定子径向倾斜。相邻的两个磁芯之间的槽形成为斜槽,定子的磁芯具有一定的聚磁效果,且定子的转矩波动较小,有利于提升盘式电机的输出转矩,提升电动车的动力。
