Embodiment Construction

[0018] figure 1 shows a motor configured according to one embodiment for use in conjunction with electronic commutation ( Figure 10 10) Stator 30 used together. This stator is designed, for example, in the form of an outer stator for use in electronically commutated internally rotating electrical machines. However, it should be pointed out that the invention is not restricted to outer stators for internally rotating electrical machines, but rather can also be used in inner stators for externally rotating electrical machines.

[0019] The outer stator 30 is preferably annular and preferably has a laminated core 32 , which is provided with a winding system 34 , and which is formed from a plurality of laminar individual laminations. As an alternative thereto, a stator core made of soft iron, for example, can be used instead of the laminated core 32 .

[0020] The lamination stack 32 is preferably provided with an upper first insulator 41 at the upper first axial end 32' and w...

Abstract

Electronic rectifier motor comprising: rotor with permanent magnet system (22) (20); Having a laminated group (32) and a winding system (34) of the stator (30), the laminated group is provided with an insulator (41) on at least one axial end (32'), and the winding system (34) comprises a plurality of coils (38A, 38B, 38C, 38D) wound by at least one winding wire (36); At least one winding wire contact element (50), which is fastened to the insulator (41) and mechanically connected to at least one segment of the winding line (36A) and conductively connected; At least one contact rail with a first region (61), a second region (62) and a third region (63), the first region is mechanically connected to the winding line contact element (50) and conductively connected, the second region is arranged with an internal thread (66) of the internal thread member (65), so that the winding system (34) and the electrical connection of the assigned voltage source, the third region of the first region (61) and the second region (62) conductive connection.

Description

technical field [0001] The invention relates to an electronically commutated electric motor, onto which electrical conductors of a contact arm provided with a threaded part can be screwed, the electrical conductors being electrically conductively connected to an associated voltage source. Background technique [0002] Such electronically commutated electric machines are used, for example, in motor vehicle transmissions, in particular dual-clutch transmissions, not only for actuating the oil pump for lubrication, but also for actuating the oil pump during gear shifting. In this case, the electronically commutated electric motor is contacted to the associated controller and thus to the associated voltage source or output stage via contact arms of the controller which are each arranged at a predetermined angle relative to the motor. The contact arms are usually made of plastic and each contain the electrical conductors required for electrical contacting. These electrical condu...
