Abstract

An optical measuring device includes at least one optical sensor, an optical waveguide connected to the optical sensor, and an evaluation unit. The optical measuring device is intended for an electrical machine including at least one conductor that is pressed into a groove of a base body, the groove having two groove lateral walls. The optical sensor and a part of the optical waveguide that is located in a proximity of the sensor are disposed in the area of the groove on a narrow side of the conductor that faces away from both groove lateral walls.
