Abstract

A rotor for a rotor assembly of an electric machine comprising a body 30 defining a magnet aperture 32, a permanent magnet 34 and a compressible component 40, where the compressible component surrounds at least a portion of the permanent magnet. The magnet and component are received within the aperture with at least a portion of the component being located between the magnet and a first wall of the aperture and where the at least portion of the component being compressed between the magnet and the first wall to retain the magnet in the aperture. The compressible component may either be removably connected to the magnet or fixedly attached to the magnet. The component may be resiliently compressible. The compressible component may extend across a first side of the magnet. The component may have an L-shaped or U-shaped cross-section and the magnet is located within the L-shaped or U-shaped cross-section. The component may be a sleeve, the sleeve having a cup configured to receive one end of the magnet. The component may partially encapsulate the magnet. The compressible component may extend around 50% to 100% of the surface of the magnet. One or both ends of the magnet and/or compressible component may be connected by adhesive to the magnet aperture. A second compressible component may also be provided. The electric machine may be used in a vehicle.
