The stator core of the rotating electric machine is made of thin laminations of magnetic steel, separated by solidx000D
insulation to prevent axial currents. If laminations are exposed to short-circuit conditions due to the insulationx000D
failure, the high temperatures that result due to the axial current flow can damage the stator. The insulationx000D
failure can initially start as a partial electrical discharge which can propagate with time and result in thex000D
insulation failure. Therefore, there is a need for regular monitoring and inspection of the insulation integrityx000D
between each two adjacent laminations. The preferred approach is to conduct the inspection while the rotor isx000D
in place. To enable rotor-in-place inspection, IRIS Power has designed, developed and marketed a specificx000D
technology referred to the Robotic Inspection Vehicle (RIV) which can move in the narrow gap between thex000D
rotor and the stator and also carry a small camera and light-weight transducers for inspection.x000D
The existing version of the RIV unit is near to the end of its useful life-span due to obsolescence of the originalx000D
components. Furthermore, the camera and the RIV control are currently implemented as two independent unitsx000D
that are not coordinated. The objective of this project is to redesign a control system for the RIV and thex000D
camera to (i) address the component obsolescence, (ii) integrate the controls of the RIV and the camera in onex000D
control platform, and (iii) provide full coordination between the RIV and the camera functions. The envisioned,x000D
unified, control unit will allow the desired coordination of measurement results and improvesx000D
detection/inspection accuracy. It is expected that the added features of the new control unit and camera willx000D
address all issues reported by existing customers, leading to increased marketability of the improvedx000D
technology.
