Abstract:
1. An endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ) for an electric motor with a rotor, a rotor shaft axis, and a stator, the endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ) having a receptacle ( 25 ) for a bearing ( 400 ) for bearing a shaft ( 100 ) of the rotor, and the endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ) being arranged in a housing ( 35 ) of the electric motor, characterized in that the endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ) has a power supply line ( 13 , 23 , 24 , 60 ; 86 , 87 , 88 ; 92 , 93 , 94 ), which is designed to connect at least one winding ( 74 ) of the stator to at least one of an electrical connection and a further winding ( 74 ) of the stator, wherein the power supply line ( 13 , 23 , 24 , 60 ; 86 , 87 , 88 ; 92 , 93 , 94 ) has a first contact face ( 12 ) and a second contact face ( 15 ), the first and second contact faces ( 12 , 15 ) being aligned parallel to the rotor shaft axis, the first contact face ( 12 ) being connected to the electrical connection and the second contact face ( 15 ) being connected to the at least one winding ( 74 ), wherein the first and second contact faces ( 12 , 15 ) are spaced from each other in a plane that is perpendicular to the motor shaft axis, wherein at least one of the first and second contact faces ( 12 , 15 ) is in the form of an insulation displacement contact, and wherein the endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ) has at least one opening ( 18 ) in order to guide a connection of the at least one winding ( 74 ) through the endshield ( 5 ; 6 ; 7 ; 8 ; 9 ; 10 ).
