The present invention relates to a coil form (100) for mounting on a magnet core (118) for a rotating electrical machine or a resolver and to a corresponding magnet core. The present invention further relates to a magneto-electric angle sensor, in particular a reluctance resolver, the stator of which is constructed by the principles according to the invention. The coil form has a winding form (102) for applying a winding, the winding form (102) comprising a recess (124) for receiving a tooth (116) of the magnet core (118), at least one holding rib (114) being integrally formed and in cooperation with a holding structure (120) of the magnet core (118) fixing the coil form to the tooth. The magnet core comprises a plurality of lamellae (136) manufactured from sheet metal, which are layered on top of one another in a plane-parallel manner and interconnected, every two lamellae which lie on top of one another being rotated through an offset angle relative to one another to form the holding structure (120).
