The invention provides a motor rotor sleeve. An electric machine includes a stator (50), a rotor (29) radially inward of the stator and including a plurality of surface permanent magnets (44), and a rotor sleeve (46) surrounding the rotor. The rotor sleeve includes a plurality of layers of fiber reinforced matrix material (56, 60). The rotor sleeve defines a ratio of rotor sleeve radius to radial thickness (r: t) between 20 and 40, and the electric machine has a maximum rotor rotational speed greater than 15000 RPM.
本发明提供了一种电机转子套筒。一种电机包括定子(50)、在该定子的径向内侧并且包括多个表面永磁体(44)的转子(29)以及围绕该转子的转子套筒(46)。该转子套筒包括多个纤维增强的基质材料(56、60)层。该转子套筒将转子套筒半径与径向厚度的比率(r:t)限定在20和40之间,并且该电机具有大于15000 RPM的最大转子旋转速度。
