Abstract
A device for contactless measurement of a rotor temperature includes a magnet supported on the rotor, electric coils which are arranged at the stator with which the rotor cooperates, and an electronic unit for measuring a voltage induced in the coil and including a component that converts the measured voltage into a temperature-proportional signal.
