I need a slip ring assembly that can handle up to 1500 watts of power with a through-bore, I've looked and have not been able to find any that can handle that amount. Does anyone have any suggestions? Or alternatives (something that rotates on one side, stationary on the other and conducts through the assembly).

 

Perhaps use the slip rings & brushes from a GM 130A alternator? That's 1800W.

Oops; those slip rings don't carry the total current; just the armature current. Next idea...

 

1500 watts - 240 volts and 6.25 amps, 12 volts and 125 amps. Brush cross section and slip ring area will vary considerably between those points.

What voltage are you handling - or current?

 

What is the full application? There may be an easier way to build it.

The voltage/current are needed, as current determines the size of the brush needed, and voltage dictates spacing.

You might check with some radar manufacturers or military surplus, these were often used to convey power to magnetrons in airborned radars.

In addition to specifying current and voltage, one would need to know RPM of operation.

 

a bit of detail.
but you may use the idea of pilot exciter for the syn.machine,i hope this would help..
