Abstract
Device for detecting fault states in an electric machine comprising a rotor and a stator arranged so as to be electrically isolated from the rotor, comprising a connection electronics system for connecting the electric machine, wherein either the stator is connected by means of an electrical connection to a first electrical potential of the connection electronics system, said first electrical potential being stable with respect to the ground potential, or the stator is directly connected to a second electrical potential, which is stable with respect to the ground potential, and the second electrical potential is connected to the connection electronics system by means of the electrical connection, wherein a first sensor for measuring a first phase current and a second sensor for measuring a second phase current and a third sensor for measuring an electrical signal of the stator is formed via and/or at the electrical connection.
