Abstract
An electric machine for a drive of a motor vehicle, having a stator, a rotor which can be rotated relative to the stator, a temperature sensor arranged and designed to capture a temperature of the stator and a rotor condition capture sensor which is arranged and designed to capture a rotational speed and/or rotational position of the rotor accommodated in a stator-fixed manner. The temperature sensor and the rotor condition capture sensor are implemented as subsystems of a common sensor system, wherein a first subsystem having the temperature sensor has an elastic thermally conductive contact element connected to the temperature sensor, which contact element is permanently fitted to a contact region of the stator. A hybrid module having this electric machine is also provided.
