To Lionel, Thanks, I had ruled this connection out because the four contacts on each of the two drums are solidly connected, but realise that this may not matter as the resistors are progressively shorted out. Will draw it out to check. Thanks, Des DPS

Thanks to you all. Did not recall that theory (I'm 75). I agree unbalance is no great problem and given that, I see a way to connect it. Des DPS

I will need to out the resitance but that is easy . My problem is to correctly connect the drum contacts of this controller, that has two sets each of four of contacts on the drum and work them into a 3 phse resistor bank keeping load currnts balanced as near as possible. I worked with such...

Thanks Waross. All the nameplate says is-- GE Controller T133 R, s/n 553711, NP 11378. Motor is-- GE CO Induction Motor Type 1I 6-15A-1200 Form L Cycles 60 HP 15 Amps 38 Volts 220 Speed no load 1200 Full load ----- Schenectady NY USA Des

I'm trying to work out the resistance connections for this controller. Motor 15hp 220v 3 phase wound rotor in good condition. Do not want to replace it as it is part of a vintage carousel. Has two sets of stepping contacts, not three. Final step three contacts. Resistors are missing. GE have no...
