Embodiment Construction

[0042] figure 1 The electromagnetic structure 2 of the electric motor is shown, which is not shown in detail, wherein the electromagnetic structure 2 is a component of the stator of the electric motor. The electromagnetic structure 2 comprises 12 coil bodies 4 made of plastic, on which a coil 6 is each wound. The coils 6 are especially made of enamelled copper wire and each have a coil winding 6a and a connection 6b ( figure 2 ).

[0043] The coil body 4 and the coil 6 are arranged in an annular circular structure 8 . Inside the circular structure 8 , the rotor of the electric motor is rotatably mounted in the mounted state, which rotates about the axis of rotation 9 during operation due to the excitation field of the electromagnetic structure 2 . Every two coils 6 are electrically conductively connected via conductor lines 10 and form coil pairs 12 ( figure 2 ). To this end, each conductor bridge 10 is in electrical contact with the connection 6 b of the corresponding ...

Abstract

The invention relates to an electromagnetic structure (2) of an electric machine, in particular an adjustment drive of a motor vehicle, comprising a number of coils (6) which are arranged to form a circular structure (8) and which comprises a coil winding (6a) and a connection (6b). Said coils (6) are respectively electrically connected in pairs by means of a conductor bridge (10) which is in contact with the respective connections (6b). Each conductor bridge (10) is arranged at an axial distance (A) from the associated coils (6), each conductor bridge (10) being arranged at least partially ina receiving element (20) of a guide plate (18, 18', 18'').

Description

[0001] This application was filed on March 10, 2015 and entered the Chinese national phase on September 9, 2016. The PCT application number is PCT / EP2015 / 054872, the national application number is 201580013065.2, and the invention name is "Electromagnetic structure of motor "A divisional application of the application. technical field [0002] The invention relates to an electromagnetic structure of an electric machine, in particular of an adjusting drive of a motor vehicle, which has a plurality of coils arranged in a circular configuration. Background technique [0003] Adjustment drives in motor vehicles, in particular servo steering systems, are usually implemented in the form of electric motors. Such electric machines are operated with three-phase alternating current and have a fixed stator with an electromagnetic structure comprising a plurality of coils arranged in a circular configuration as magnetic poles. These coils each have coil windings and terminals made of e...
