Resolver and its fixing on an electric machine

摘要

An electrical machine has a ring magnet (34) arranged rotationally tightly on a rotor and having an inner surface (44), which is force-transmissively joined to the outer radial surface (42) of a wave-shaped component. Between the inner surface and the outer radial surface (42) are arranged alternately over its surface, radial contact areas (46) and radial free spaces (48).
