Embodiment Construction

[0059] In the following, advantageous embodiments of the invention are described in more detail with reference to the accompanying drawings. In this regard, it should be noted that although a magnetic core which may be used as a stator of a reluctance solver is always presented below, the invention is naturally applicable to any type of rotating electrical equipment. This means that the type of fastening according to the invention of the coil former can also be used for electric machines and motors, both on the stator core and on the rotor core.

[0060] Further, the invention is not limited to those embodiments in which the teeth of the magnetic core protrude back inwardly from the annular yoke towards the central axis; the magnetic core teeth placed on the outer periphery of the magnetic core can also be arranged correspondingly in an equivalently similar manner There is a bobbin according to the invention.

[0061] Finally, the coil former according to the invention can be...

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).

Description

technical field [0001] The invention relates to a bobbin for mounting on a magnetic core of a rotating electric machine and to a corresponding magnetic core. The invention further relates to a magnetoelectric angle sensor, in particular a reluctance resolver, the stator of which is constructed according to the principles of the invention. Finally, the invention relates to a manufacturing method for manufacturing a reluctance solver of this type. Background technique [0002] A reluctance resolver of this type has an at least partially soft magnetically rotationally symmetric stator and an at least partially softly magnetically rotationally symmetric rotor, the stator and rotor being positioned opposite each other so as to form a gap. The reluctance in this gap varies periodically based on the shape of the rotor which changes around the circumference. [0003] The angle sensor comprises a magnetic flux transmitter which is arranged on the stator and generates a predetermine...
