Title:
MAGNET-HOLDING PLATES
Document Type and Number:
WIPO Patent Application WO/2015/075364
Kind Code:
A3
Abstract:
The invention essentially concerns a rotor (100) comprising an axis of rotation (X) for an electric machine comprising: - a central core (101), - arms (102) extending radially relative to the core (101), these arms (102) each comprising two rims (105) extending on either side of the arms (102), - permanent magnets (114) positioned inside housings (111) that are each delimited by two opposing lateral faces of the two adjacent arms (102), an outer face of the core (101) extending between the two adjacent arms, and the rims (105) of the arms of the rotor (100). Plates (119) made from a material more flexible than the permanent magnets (114) are positioned between the rims (105) of the arms (102) and the face of the permanent magnet (114) facing away from the axis (X) of the rotor (100) to hold the magnets during centrifugation, and the permanent magnets have a height in the axial direction and a width in the orthoradial direction, said plate having, in the axial direction, a height close to the height of the permanent magnets, the ratio between the width of the plate and that of the magnet being between 0.9 and 1.1, without being equal to 1.
