Abstract: A permanent magnet rotor having a shaft, a hollow cylindrical permanent magnet and an elastic connecting medium between the shaft and the permanent magnet. The permanent magnet is arranged co-axially around the shaft to ensure that the permanent magnet is mounted securely, that it is not damaged during large temperature fluctuations, and that it is not deflected impermissibly from the axis of rotation in case of heavy radial load. A simple installation process uses a mechanical connection between the shaft and the permanent magnet. This task is performed by virtue of the fact that an elastic connecting medium is arranged along the periphery of the shaft at several first areas in which the distance between the shaft and the permanent magnet is enlarged. These first areas are separated from the second areas in which the distance between the shaft and the permanent magnet is minimized but not zero.
