Title:
ROTOR FOR AN ELECTRIC MACHINE HAVING MAGNETS SECURED BY A THERMOPLASTIC MATERIAL AND CORRESPONDING MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/091943
Kind Code:
A3
Abstract:
The invention relates to a rotor for an electric machine and to a method for manufacturing such a rotor. The rotor (15) comprises a rotor body (9) having a plurality of holes (5) and a plurality of magnets (7) that are accommodated in the holes (5) of the rotor body (9). The magnets (7) are enclosed at least partially by a thermoplastic material and secured by the latter in the holes (5). In comparison to conventional duroplastic adhesives, the thermoplastic materials enable a simpler positive locking securing of the magnets (7) in the rotor body (9). Magnetic or magnetizable particles can be embedded in the thermoplastic material (13), such that a gap (11) between the magnets (7) and the walls of the holes (5), which gap is filled with the thermoplastic material (13), can contribute to the total magnetic field generated by the rotor.
