1. An electric machine comprising: a stator and a housing, wherein
an electrically insulating torque support mechanically connects the stator to the housing;
wherein a shaft of a rotor of the electric machine has a flange made of electrically insulating material, the flange of the shaft is configured to receive a fastener;
wherein the flange of the shaft is connected to a flange of a bearing shaft with a fastener, and the bearing shaft is housed in a bearing arranged in the housing;
wherein the shaft is electrically isolated from the bearing shaft; and
wherein the flange of the shaft abuts the flange of the bearing shaft.
