Howdy folks!
I'm thinking to build I fvd testing rig to learn and test troubleshooting, dealing with different wire lengths playing with oscilloscope etc. I've done plenty of general electrical work but not much electronics.
General outline:
3 hp 3ph motor belt drive to 4.25 hp pm dc motor wired to resistor bank.
Current thought is to use a bank with high wattage low resistance 3 ohm or so and use PWM control and an arduino to simulate various real world conditions like high starting loads, sudden loads etc..
Cooling is an obvious issue, what else ?
Thanks bunch!
