Electric machine

摘要

Electric machine (10), in particular an alternating current generator, comprising a rotor (20) having a rotational axis (26), a stator (16) made of a stator iron (17) and a stator winding (18) inserted therein, said winding having conductor ends (228), which are interconnected with a rectifier device (139), a controller (231) for controlling an excitation current, and a cooling device in the rectifier device (139), comprising a first cooling body (53), which has at least one receptacle (66) on which a current rectifier (147) is received, and a second cooling body (117), wherein the cooling body (117) has at least one receptacle (120) on which a current rectifier (150) is received, an interconnection unit (144), which interconnects the current rectifiers (147, 150) into a bridge circuit, wherein the interconnection unit (144) comprises a plurality of integral guide sockets (225) in which conductor ends (228) of the stator winding (18) are received, wherein a guide socket (225) is disposed between the end shield (13.2) and the controller (231) in the direction of the rotational axis (26).

主权项

1. An electric machine (10) having a rotor (20), which has an axis of rotation (26), a stator (16) including a stator iron (17) and a stator winding (18) inserted therein, which winding has conductor ends (228), which are interconnected with a rectifier device (139), a regulator (231) for regulating an excitation current, and a cooling device in the rectifier device (139), said cooling device having a first heat sink (53), which has at least one receptacle (66), on which a current rectifier (147) is received, having a second heat sink (117), wherein the second heat sink (117) has at least one receptacle (120), on which a current rectifier (150) is received, and having an interconnection unit (144), which interconnects the current rectifiers (147, 150) to form a bridge circuit, wherein the interconnection unit (144) has a plurality of integrally formed guide stubs (225), in which conductor ends (228) of the stator winding (18) are received, characterized in that an arm (234) of the interconnection unit (144) connects one guide stub (225) integrally to another, shorter guide stub (225), wherein the shorter guide stub (225) and the arm (234) are disposed between an end shield (13.2) and the regulator (231) in the direction of the axis of rotation (26).
