I’m helping a buddy setup his dual VESC for a foil-board. He has a dual VESC and the plan is to gang the outputs to drive a single motor. Apparently this is the way it’s intended to be done.
I’ve setup single and dual motor boards with VESC’s, and I’ve driven them independently with PPM cable Y’d, as well as slaving them with CANBUS. But ganging the outputs makes me nervous because the commutation timing on both sides of the dual VESC will have to be identical. I’m guessing there’s a setting that uses only one DRV IC, but the output FET’s from both sides. Any tips on the VESCTool setup for this configuration would be greatly appreciated.
UPDATE: To save anyone the heartache of following this thread just to learn that I was an idiot… It turns out the VESC in question is a Flipsky FSESC 75-300, which b264 has pointed out is NOT a dual VESC. Thanks b264.
It looks like I definitely came to the right place. I’m glad I asked. I’m not sure which unit or firmware it is yet. But he’s bringing it by tomorrow, so I’ll find out and post it here. Thanks!
So here it is. I suspect it’s a single-MCU, but I don’t know that for sure. It only has one PPM input, one USB input, one Hall sensor input port, etc. Interestingly, it’s got 3 sets of battery inputs, and 2 sets of motor outputs.
It comes with either an aluminum case or a waterproof case with water-cooling inlets and outlets. We’ve got the waterproof one…
This image on their website shows the battery input and the motor outputs ganged…
yea, that’s a single drive esc, basically all 3 battery connectors goes to battery, and those 3 sets of 2 wires are like the 3 individual phase wire for regular esc.
It’s not that I “want” to do it. My buddy bought all this gear to make an electric foil-board. He isn’t familiar with brushless motors, VESC’s, etc. So he asked me to help. The manufacturer shows the unit being used this way. It has two sets of motor outputs, so I assumed it was a dual VESC. But they gang the outputs to a single motor.
