  9. Do the AEGIS SGR™ Conductive MicroFibers™ touch the shaft?
  10. Will AEGIS SGR™ remain equally effective during its long service life?
  11. Will the AEGIS SGR™ cause wear to the shaft of the motor?
  12. Why do conventional shaft grounding brushes wear out?
  13. Why do conventional shaft grounding brushes need maintenance?
  14. Should conventional carbon block copper shaft grounding brushes be replaced by AEGIS SGR™ on VFD motors?
  15. Where do the VFD induced shaft voltages go with no AEGIS SGR™ brush installed?
  16. Why are these shaft currents so destructive?
  17. What does bearing frosting look like?
  18. What does bearing fluting look like?
  19. What happens to the motor as frosting and fluting take place in the bearings?
  20. Will electrical bearing damage always occur in a VFD application?
  21. How about VFD duty motors, are they safe from bearing damage?
  22. How about IEEE 841 motors, are they safe from electrical bearing damage?
  23. We just installed VFDs on many of our motors and so far everything is OK, should I be worried about shaft current?
  24. From a preventative maintenance perspective what would you recommend?
  25. Can I operate the AEGIS SGR™ over the shaft keyway?
  26. What is the wear rate of the micro fibers?
  27. What is the best way to measure shaft voltage?
  28. Can an RMS measurement be used to test for the presence of shaft voltages?
  29. Will the AEGIS SGR™ work in washdown duty motor?
  30. Should one or two AEGIS™ SGRs be installed on the motor?
  31. If AEGIS SGR™ is installed outdoors, will water affect performance?
  32. Does any corrosion occur to AEGIS SGR™ with water?
  33. Is it possible to press the SGR into the motor housing instead of using the mounting brackets?
  34. Where does the "category" of "medium" voltage motors begin? What input voltage?
