So I had a thought while in the shower today. I was trying to figure out a load bank for testing RPC's. Thought came to me on how to load a motor so it would actually be working. Came up with locating 3 phase pump motors with the pump attached and a 55 gallon drum full of water. Pull the water from the bottom and pump it into the top with a restriction plate in the output line. This of course would build back pressure and cause the motor to actually do work. I was never a fan of turning on a lathe, taking a cut with the lead screw and then running over and taking measurements. A rig like this could be several motors of various sizes all doing the same thing and then having metering in a panel with voltage and current for all three legs. Any thoughts?
