Abstract :
Monitoring systems for this part of a rotating machine are difficult to elaborate. Effectively the problem is to transmit this information from the rotating rotor to the fixed stator, given the inherent presence of the electromagnetic field. In this paper we propose a new measurement device using optical fiber for all sensor types. This device is not subject to electrical or magnetic interference. Application for thermal monitoring has been tested by detecting a rotor fault in the cage of an asynchronous motor
