Iris Power Robotic Inspection Vehicle – (RIV800)

Offline Low Profile Robotic System for Machine Testing, Inspection and Imaging

The Iris Power RIV800 Robotic Inspection Vehicle and Camera System, allows a visual inspection of the generator stator and rotor, including checking the air vents for debris, with or without removing the rotor. The robotic inspection vehicle also provides an automated means of EL CID™ low-flux core testing and SWA stator wedge analyzer testing.

The magnetically supported Robotic Inspection Vehicle (RIV 800) has been developed to provide an automated scanning method for the EL CID™ Evolution  stator core interlaminar insulation test equipment. The vehicle allows scanning of the stator bore of a generator or large motor, in order to test the integrity of the stator lamination insulation out more efficiently. The equipment can also be adapted to carry other lightweight attachments for stator inspection including the mini-camera or wedge tightness probe. A single control unit is used to provide power and control to the vehicle and camera module.

The RIV 800 is primarily designed for automated testing stator cores with EL CID™ low-flux core tester with the rotor removed however, is also can be used to test machines by insertion into the air-gap with the rotor in place if the rotor retaining ring to stator gap is sufficiently large. The new RIV 800 controller has been developed in collaboration with a University of Toronto Laboratory.

The Iris Power RIV Camera System provides a flexible system for Rotor-in-Place inspections of large generators. It is fitted to the Iris Power Robotic Inspection Vehicle which can be moved along the stator slots. The camera system includes an integral light. The camera and light are directed at a 45° mirror, which can be remotely rotated through 360° to allow scanning of the stator or rotor as well as looking forward along the air-gap. The camera can also be focused remotely. The system allows a visual inspection of the generator stator and rotor, including checking the air vents for debris, without removing the rotor. The video output is displayed on a 150 mm color TFT LCD integral monitor in the control unit. Composite video output is provided for feeding to a second monitor or video recorder.

Works with These Assets


  • Reduce overall cost of maintenance by providing faster testing with only one operator
  • Magnetically self supporting on steel surface to reduce human fatigue, stress and accessibility concerns
  • Fits into the 35 mm air gap for rotor-in-place testing
  • Guidance system detects the edges of the stator teeth to follow a straight line and measures distance using an encoder wheel.
  • Curvature adjustment accommodates the tractor in stator cores of various sizes
  • AUTO mode allows the RIV to stop at a pre-set distance and then move only in the opposite direction
  • Variable speed adjustment

  • Focus on the stator core surface, stator air vents, or rotor surface
  • Scans image while conducting wedge tightness or ELCID test
  • Fits to the Robotic Inspection Vehicle for moving along stator slots
  • Assists positioning for Rotor-in-Place wedge tightness testing
  • Visual inspection for debris in the air-gap
  • Image can be adjusted for 360-degree angle and focus
  • Built-in dual light source


  • Miniature SWA probe for wedge tightness detection
  • 20, 25, 35cm flat Chattock sensors for EL CID™ low-flux core testing
