Re: pic: Inverted CIM 2-Speed Gearbox
I'd lower your low gear quite a bit. For 2 CIM gearboxes, you wanna pull around 40 amps each pushing in low gear, so you don't trip the 40A breakers very easily. Between voltage drop and the breaker safety margin, you can afford to draw a bit more theoretical current, but no real need to push it. You're not driving in low gear to go fast. Around 6 FPS (81% speed loss constant) is roughly where you want to be, not 10.
