由于隔磁件能够与隔磁腔的腔壁连接，故而，能够保证隔磁件与隔磁腔的配合尺寸，也 即，能够保证隔磁件、磁钢、护套结构和转子芯轴的配合尺寸，不会出现隔磁件移位的情况，为保证转子的使用性能提供了有效且可靠的结构支撑。
可以理解的是，相邻两个磁钢的侧壁形成隔磁腔的一部分腔壁，隔磁件位于隔磁腔内，故而，可保证相邻两个磁钢之间夹设有一个隔磁件，可保证隔磁件的隔磁效果。

护套结构120的内表面和转子芯轴110的外表面之间合围出安装腔室。
多个磁钢130位于安装腔室内，且多个磁钢130间隔分布于转子芯轴110的周侧。
多个磁钢130中任意两个相邻的磁钢130和安装腔室的腔壁之间合围出隔磁腔150。
每个隔磁腔150内设有一个隔磁件140，隔磁件140连接隔磁腔150的腔壁。
详细地，转子100包括转子芯轴110、护套结构120、多个磁钢130和多个隔磁件140。其中，多个磁钢130均位于转子芯轴110的周侧，且多个磁钢130沿转子100的周向间隔布置。多个磁钢130中任意两个相邻的磁钢130和安装腔室的腔壁之间合围出隔磁腔150，也即，多个磁钢130、转芯轴的外表面和护套结构120的内表面之间形成多个隔磁腔150，每个隔磁腔150内设有一个隔磁件140，且隔磁件140连接隔磁腔150的腔壁。
由于隔磁件140能够与隔磁腔150的腔壁连接，故而，能够保证隔磁件140与隔磁腔150的配合尺寸，也即，能够保证隔磁件140、磁钢130、护套结构120和转子芯轴110的配合尺寸，不会出现隔磁件140移位的情况，为保证转子100的使用性能提供了有效且可靠的结构支撑。
可以理解的是，相邻两个磁钢130的侧壁形成隔磁腔150的一部分腔壁，隔磁件140位于隔磁腔150内，故而，可保证相邻两个磁钢130之间夹设有一个隔磁件140，可保证隔磁件140的隔磁效果。
如图1、图2、图3、图4和图5所示，在本公开的一些实施例中，转子100包括转子芯轴110、护套结构120、多个磁钢130和多个隔磁件140。
