ABSTRACT:
A stator for an electrical machine, comprising an outer ferromagnetic flux return ring, a permanent magnet system arranged inside the flux return ring, and a face plate supporting the flux return ring and the permanent magnet system. The latter comprises at least four permanent magnets, each of which is shaped cylindrically at its outer surface, and an equal number of magnetically conductive link means, each of which abutts the inner surface of two adjacent permanent magnets. The link means serve to support the permanent magnets and may be bonded to the same. The stator is easy to manufacture with a low toleranced air gap and is of a rigid construction.
