    Circuit Model for a Rotary Contact?

    Thanks again, everyone, for your replies. @Tom.G: Your suggestion got me thinking and after some digging I found the following IEEE article about analytical modeling of slip rings. I'll http://ieeexplore.ieee.org/document/4072999/?reload=true I think that I can extract the necessary theory...

    Circuit Model for a Rotary Contact?

    Hi Everyone, Thanks very much for your replies, let me see if I can address them: @berkeman: Thanks for the waveform model, that's quite helpful; I'm afraid I don't follow your logic in modeling the contact as a relay though? @tech99: 10kA seems about right for a median amperage value, I am...

    Circuit Model for a Rotary Contact?

    Hi Everybody, First post on the forum, this one's stumped me I'm afraid. I'm basically trying to model a rotary connection in an AC circuit, and I'm having a bit of trouble with it. Ideally I'd like a reasonable approximation with conventional circuit elements. Basically I've got a...
