That's the ones. I remember that one of our tests was to wire a DC motor. We had to spin the motor and measure the resistance between the wires to find the armature ect.

Here’s one for you John, it was a 250HP fan. The b*****d thing bit me when fault finding on it. The open type ACB’s tripped just as I was stood in front of them. It tripped at 1250A The armature resistors were cast iron grids
