Abstract

An arrangement (1) for an electric machine (2, 2') comprises: a first winding system (WS1) and a second winding system (WS2), wherein at least one electrical conductor (120) of the first winding system (WS1) and at least one electrical conductor (121) of the second winding system (WS2) are at least partially wound around a common winding axis (A), wherein turns of the electrical conductors (120, 121) alternate in a direction of the winding axis (A); an inverter system (13) with a first inverter (134A) for the first winding system (WS1) and a second inverter (134B) for the second winding system (WS2); sensors (133) for sensing at least one electrical parameter of the first winding system (WS1) and at least one electrical parameter of the second winding system (WS2); and a control unit (131) configured to perform a test of the winding systems (WS1, WS2) by: controlling the first inverter (134A) to set the first winding system (WS1) to a first electrical potential (HV+) and/ot to control the second inverter (134B) to set the second winding system (WS2) to a second electrical potential (HV-) to create a potential difference between the winding systems (WS1, WS2); receiving corresponding sensor signals from the sensors (133); and analyzing the sensor signals.
