Hi,
Would any of you guys know of dust free shaft grounding for an AC motor, this is needed as we need insulated bearings on NDE and DE but as the motor will be in a clean room dust from contact brush style grounding device is not allowed. I know there are some products such as AEGIS but i have no experience with them. If there is any other way of getting around this, I was thinking of reducing switching freq on VSD as a partial solution and HF grounding straps but any help would be appreciated.
