I tested out that big inductor (48 pounds) with the nichrome wire (4 strands of 12 gauge each). The nichrome was 0.14 Ohms and was in a big bucket of water. It was just liike a motor! Perfect current control. I could even ramp up the duty to 100%. I tested it out on a controller kit that was sent to me to test. At 100% duty, at 24v it was using about 170 amps. I also ordered some more Nichrome so I could do higher voltage testing, and keep the current from going into the stratosphere. It really works as a good motor simulation. Plus you don't have to worry about the motor running away when testing new controllers that fail ON.
