Problems solved by technology

[0003] The disadvantage of such an embodiment is that such a circuit board is not suitable for use in applications at high temperatures, since then the soldered connections on the circuit board would loosen
In addition, there is the risk of destroying the electrical connection between the circuit board and the conductor elements of the plastic bearing cover at high vibration loads of the electric machine

Embodiment Construction

[0030] figure 1 An embodiment of a fully assembled electric machine 10 is shown with a stator 16 mounted in the housing 14 of said electric machine 10 . In this case, the stator 16 has a coil former 36 , which is designed individually, for example, as a single segment 62 and around which an electrical winding 17 is wound. The housing 14 serves here as a pole pot 15 which forms a magnetic non-return for the electrical winding 17 . Pole pot 15 has a flange 32 at its open end, onto which the further components are fitted. in accordance with figure 1 In an embodiment, the pole pot 15 has a mouth at its bottom surface 40 through which the rotor shaft 20 protrudes so as to transmit the torque of the motor 10 to a transmission not shown via a driven element 64 Institutional components. A first bearing seat 70 is formed on the bottom surface 40 , in which a first rolling bearing 72 is inserted. The inner ring 73 of the first rolling bearing 72 is here firmly connected to the roto...

Abstract

An electrical machine (10) and a method for producing such a machine, with a pole pot (15), in which a stator (16) and a rotor (18) are held, and axially on the open side of the pole pot (15) a connector housing (33) with an integrated terminal connector (37) is arranged, wherein the connector housing (33) has a circumferential wall (83), which lies axially against the pole pot (15), and the circumferential wall (83) has radial windows (110), in order to make electrical contacting of electrical contacts (30) of the connector housing (33) with electrical mating contacts (133) of the stator (16) possible after the placement of the connector housing (33) onto the pole pot (15).

Description

technical field [0001] The invention relates to electric machines and methods for producing such electric machines. Background technique [0002] An electrical machine is known from DE 10 2011084 763 A1 in which a stator is arranged in a pole pot. A cover part, in which the rotor shaft is mounted, is arranged on the pole pot. In this case, the cover part is made of plastic and has electrical conductor elements for connecting the electrical windings of the stator. In this case, the coil wire ends of the winding are guided axially through the cover part and are connected to the conductor element on the upper side of the cover part. The cover part has a lateral extension, which is designed as a connector plug, the pins of which are connected to the conductor element and to the printed circuit board. A signal transmitter for detecting the rotor position is arranged at the free end of the rotor shaft. A printed circuit board is located axially opposite the signal transmitter,...
