Embodiment Construction

[0028] figure 1 An embodiment of the electric machine 10 is shown completed with the stator 16 installed in the housing 14 of the electric machine 10 . In this case, the stator 16 has a coil carrier 36 which is designed individually, for example, as a single segment 62 and which is wound with an electrical winding 17 . The housing 14 serves here as a pole pot 15 which forms the magnetic back iron for the electrical winding 17 . Pole pot 15 has a flange 32 at its open end, onto which the further components are placed. in accordance with figure 1In the exemplary embodiment, the pole pot 15 has an opening on its bottom face 40 through which the rotor shaft 20 protrudes in order to transmit the torque of the electric machine 10 via the output element 64 to a transmission element not shown. A first bearing seat 70 is formed on the bottom surface 40 , into which a first rolling bearing 72 is inserted. The inner ring 73 of the first rolling bearing 72 is here fixedly connected to...

Abstract

The invention relates to an electric machine (10), in particular an electronically commutated EC motor, and a method for producing same, comprising a pole-well (15) in which a stator (16) and a rotor(18) are accommodated, and a plug housing (33) having an integrated connection plug (37) is arranged axially on the open side of the pole-well (15), wherein the plug housing (33) is surrounded by a metal cover (81) over its entire circumference, which is sealingly connected to the pole-well (15), wherein the connection plug (37) projects outwards through a recess (39) in the metal cover (81) in adirection axially opposing the rotor (18), and the plug housing (33) is sealed against the metal cover (81) by means of a sealing ring (84).

Description

technical field [0001] The invention relates to an electric machine of the type according to the independent claims and to a method for producing such an electric machine. Background technique [0002] An electric machine is known from DE 10 2011 084 763 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. The cover part here 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 laterally protruding connector pin, the pins of which are connected to the conductor element and the printed circuit board. A signal transmitter for rotor orientation detection is arranged at the free end of the rotor shaft. A printed ci...
