Embodiment Construction

[0031] figure 1 A first embodiment of a rotating electric machine 1 is schematically shown. Electric machine 1 has a stator 2 and a rotor 4 rotatable relative to stator 2 about an axis of rotation 6 . figure 1 A sectional view with a section perpendicular to the axis of rotation 6 is shown.

[0032] The rotor 4 has an annular reaction element 5 which extends around the axis of rotation 6 along a reaction element circumference 11 .

[0033] The stator 2 has three segment pairs 3 of two active component segments 7 , 9 arranged at equal intervals along the reaction element circumference 11 . The two active part segments 7 , 9 of each segment pair 3 are arranged on the diametrically opposite side of the reaction element 5 with respect to the reaction element circumference 11 , so that the arc of the reaction element circumference 11 lies between the two active parts. The component sections 7 , 9 extend between them.

Abstract

The invention relates to a rotating electric machine (1) having a stator (2) and a rotor (4), which is rotatable about a rotation axis (6) relative to the stator (2). The rotor (4) has an annular reaction element (5), which extends along a reaction element circle (11) about the rotation axis (6) and has a plurality of magnetizable regions (25) arranged one behind the other along the reaction element circle (11), wherein a non-magnetic region (23) is arranged between every two adjacent magnetizable regions (25). The stator (2) has at least one segment pair (3) comprising two active sub-segments(7, 9), between which a circular arc of the reaction element circle (11) extends, wherein a first active sub-segment (7) of each segment pair (3) has a plurality of electromagnets (13) arranged one behind the other along the course of the circular arc and the second active sub-segment (9) of the segment pair (3) has a plurality of permanent magnets (21) arranged along the course of the circular arc.

Description

technical field [0001] The invention relates to a rotating electric machine. Background technique [0002] A rotating electrical machine has a stator and a rotor rotatable relative to the stator about an axis of rotation. The stator and / or rotor have magnets for generating a magnetic field. The magnets are electromagnets and / or permanent magnets and are generally arranged on the stator and / or rotor along a circle around the axis of rotation. In the case of large rotating electrical machines, that is to say if the circles have a large radius, correspondingly many and / or large magnets are required. This results in high costs for the magnet assembly of such machines. Contents of the invention [0003] It is an object of the invention to provide a rotating electrical machine which is improved especially with regard to the cost of magnet assembly. [0004] This object is achieved by the features of claim 1 . [0005] Advantageous refinements of the invention are the subjec...
