ABSTRACT:
An electrical machine comprises a stationary first section (1) and a second section (5) which is movable relative to the stationary section. At least one of the sections comprises a soft-magnetic part (7) and a hard-magnetic part (9). A surface (7a) of the soft-magnetic part and a surface (9a) of the hard-magnetic part are fixed intimately to one another by direct bonding.
