Abstract: 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).

Abstract: The present invention relates to a reluctance resolver (100) with an at least partially soft magnetic stator (104) and an at least partially soft magnetic rotor (102) which oppose each other by forming an air gap. The magnetic resistance in the air gap changes periodically on account of a configuration of the rotor that varies over the circumference. The angle sensor has a magnetic flux transmitter which is arranged on the stator and generates a predefined magnetic flux distribution in the air gap via at least one pair of poles. Furthermore, a magnetic flux receiver, which measures the intensity of the magnetic field via at least two pairs of signal poles arranged offset from one another at an angle, is arranged on the stator, wherein an angle value for a position of the rotor in relation to the stator can be derived from the two receiver signals.
