Spool for mounting on a magnetic core, magnetic core for reluctance resolver and method of manufacture

摘要

The present invention relates to a coil former (100) for mounting on a magnetic core (118) for a rotating electrical machine or a resolver, and to a corresponding magnetic core. Furthermore, the present invention relates to a magnetoelectric angle sensor, in particular a reluctance resolver, the stator of which is constructed according to the principles of the invention. The coil former has a winding body (102) for applying a winding, the winding body (102) having a receptacle (124) for receiving a tooth (116) of the magnetic core (118), at least one holding rib (114) which is formed in the Cooperation with a holding structure (120) of the magnetic core (118) fixes the coil body to the tooth. The magnetic core comprises a plurality of laminations (136) which are laminated and connected to one another plane-parallel and connected to one another, two laminations lying one above the other being rotated relative to one another by an offset angle in order to form the holding structure (120).
