VESC - Open source ESC

[Dr_T]

Coincidentally, I finally started playing a bit with mine today; indeed it's far from plug and play and not something for mass market, all the input variables make me feel like I'm new at the hobby again :). Should be fun to fiddle around a bit with though, if I can make it last.

Only tested it a bit on the bench so far. Cool to feel the difference between conventional "PWM control" ESCs vs. the "Current control" mode of the VESC. Was confusing in the beginning, as at no load, it spins up to max RPM at the slightest throttle input. Thought my Tx calibration was off, but it all made sense when I realized that's exactly how Current control works :). Curious to find out how it drives and how much power it can handle without cooling. To be continued... unless magic smoke :D.

Typically there are two loop levels when doing current control --

An outside loop doing RPM control and an inside loop doing current control.

Without the RPM control, yes, RPM will be uncontrolled under current control.
