| 摘要 |
The object of the invention is a permanent magnet module (2) comprising at least two permanent magnets (6) with the first magnetic pole on the first plane surface (20) and the second magnetic pole on the second plane surface, and a cover (3) at least partially enveloping the permanent magnets (6). According to the invention the cover (3) of the module is magnetically conductive and comprises a top surface, substantially covering the first plane surface (20) of the permanent magnet, and a bottom surface (3), substantially covering the second plane surface of the permanent magnet. The cover (3) is at least partially open at the side surfaces (24) of the permanent magnet (6). Another object of the invention is a rotor for an electrical machine, the rotor having permanent magnets fitted into a corresponding module.
