Abstract

The invention relates to an electrical machine (10) comprising an annular pole housing (28), in which a plurality of magnets (212), particularly permanent magnets, are accommodated, comprising at least one holding device (214) which is accommodated in the pole housing (28). An assembly made of magnets (212) and ferromagnetic components (230) is attached to at least one resilient annular element (216) which impinges on the at least one resilient holding device (214) or on a ferromagnetic component (230) in the pole tube (28).
