Robot improves motor inspection

Called the ABB InSight, the 8.5 mm high robotic inspection crawler is tethered to a control cabinet that features two large and three small monitors. A joystick and speed controller is used to navigate the crawler – which uses a magnetic roller mechanism – around the air gap and to adjust four of the five cameras.

On board LEDs illuminate the journey, while a microprocessor, accelerometers, RS485 communication and video multiplexing provides a video feed of the stator and rotor core, winding, wedges, stator teeth, air ducts, rotor support blocks and parts of the end windings.
