Abstract

The invention relates to a rotor (10) for a reluctance machine (E) comprising pole regions (16) arranged along a circumference (12), comprising a transition surface (14) for a transition of a magnetic flux to an air gap (L) of the reluctance machine (E), wherein each adjacent pole region (16) is magnetically coupled via a flux conducting element (18). The rotor (10) should be able to be configured with a high number of poles, without overly compromising the power factor. The rotor (10) additionally has a shaft (D), on which the flux conducting elements (18) are each formed by a block (28, 34), wherein a material (22) of the block (28, 34) has a magnetic anisotropy with an easy axis (24) and a hard axis of magnetizability, and the easy axis (24) is arranged, at least ins sections, tangentially to the circumference (12) or at least at an angle of less than 25º relative to the tangent of the circumference (12).

Description

Technical field [0001] The invention relates to a rotor for a reluctance machine, that is, a rotor without its own electric or magnetic excitation device. Instead, the rotor has pole regions arranged along the circumference, the pole regions having transition surfaces through which the magnetic flux can enter the pole regions from the air gap of the reluctance machine or from the pole regions. Leave. Adjacent pole regions are magnetically coupled via magnetic flux guiding elements. A motor with a rotor according to the invention and a method for manufacturing the rotor also belong to the invention. Background technique [0002] Conventional magnetoresistive armatures are generally composed of anisotropic soft magnetic materials that have recesses that can be filled with air. The recess thus forms a magnetic flux cutoff. The magnetic flux cutoff generally affects the mechanical stability of the armature. [0003] In the reluctance machine, the power factor consphi decreases as ...
