Title:
ARRANGEMENT HAVING AN ELECTRIC MACHINE AND METHOD FOR OPERATING AN ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/020500
Kind Code:
A1
Abstract:
The invention relates to a method and arrangement having an electric machine, comprising a stator (4) and a rotor (1) and an infrared temperature sensor, wherein the detection field of the infrared temperature sensor is directed at an outer surface of the rotor (1). The infrared temperature sensor is a thermopile (6) for radiometrically contactlessly detecting a temperature of the rotor (1), the thermopile being arranged in a slot of the stator (4) and being compatible with standard slot-sealing-wedge components of the electric machine with regard to assembly, and thus enables the operational monitoring of the thermal state of an electric machine in a novel manner, such that adapted power states can be achieved.
