摘要
The invention relates to a resistance module for increasing runup torque for a rotor of an electric machine comprising a rotor winding (21). Furthermore, the invention relates to an exciter (20), a rotor and an electric machine, which each have at least one such resistance module. In order to provide an alternative to known solutions for increasing the runup torque, it is proposed that the resistance module has: —a first connection point (1) and a second connection point (2), —at least two electrically conductive layers (3, 4, 23), wherein the at least two layers (3, 4, 23) are electrically connected to the first connection point (1) and to the second connection point (2), wherein the at least two layers (3, 4, 23) each surround an axis (5) of the resistance module at least partially in the circumferential direction and each have a layer start point (6) and a layer end point (7), —a corresponding first insulating layer (8), which is arranged in each case between two layers (3, 4, 23), —a corresponding tie point (9) at which the layer end point (7) of a corresponding layer (3, 4, 23) is electrically connected to the layer start point (6) of the corresponding following layer (3, 4, 23).
