Abstract
A magnet arrangement includes (a) a first and a second head ring magnet each having a substantially circular geometry with respect to a center axis and (b) a central ring magnet having a substantially circular geometry with respect to a center axis. The central ring magnet is disposed between the first and second head ring magnet in direction of the center axis. At least one of the magnets includes a first number of first magnets having at least one trapezoidal cross section and a second number of second magnets having at least one rectangular cross section. The second magnets are disposed in between the first magnets in circumferential direction. With this geometrical arrangement, magnets having a trapezoidal cross section include a guidance for a magnet having a rectangular cross section allowing the movements in radial direction of these last magnets.
