The invention provides a rotor, a disc type motor, a motor driving system and a vehicle. The rotor comprises: a fixed sleeve comprising 2P accommodating grooves arranged along the circumferential direction of the fixed sleeve, P being an integer greater than or equal to 1; and the magnetism gathering structure comprises 2P composite magnetism gathering parts, each composite magnetism gathering part is fixedly contained in one corresponding containing groove, and each composite magnetism gathering part comprises a permanent magnet structure and a soft magnetic structure which are embedded with each other. The magnetic gathering structure is formed by splicing the 2P composite magnetic gathering components along the circumferential direction of the fixing sleeve instead of an integral structure formed by winding, so that the outer wall of each composite magnetic gathering component can be well connected with the inner wall of the accommodating groove in a matched manner, and the stability of the magnetic gathering structure and the fixing sleeve (or other rotor structural parts) is improved. Such as a rotating shaft), so that the strength of the rotor is improved.
本申请提供一种转子、盘式电机、电机驱动系统及车辆。转子包括:固定套,包括沿所述固定套的周向设置的2P个收容槽,所述P为大于或等于1的整数;及聚磁结构,包括2P个复合聚磁部件,每个复合聚磁部件固定收容于一个对应的所述收容槽内,所述复合聚磁部件包括相互嵌设的永磁结构与软磁结构。聚磁结构通过2P个复合聚磁部件沿固定套的周向拼成,而非通过卷绕而成的整体结构,这样一来,各个复合聚磁部件的外壁能够很好地与收容槽的内壁配合连接在一起,提高了聚磁结构与固定套(或者其它转子结构件,例如转轴)之间的连接稳定性,进而提升了转子的强度。
