I had some awful experiences using off the shelf controllers and low kv motors, 50-80kv Alien Power Systems c80100s, trying to get them to start with VESCs required massive spikes of current. Something I'd not seen with higher kv motors, ~170kv. Also those wires look awful thin to be slinging...

Yeah, Euan does have an unhealthy fixation with SMOL ESCs and while I don't disagree with you, he's been getting some promising results from the latest A200S.

A friend and I made a massive MOSFET comparison spreadsheet: https://docs.google.com/spreadsheets/d/1X2rFGrNOMii--7HAyMUkI9mJYP8kVNinVh1hMb_GhCk/edit?fbclid=IwAR1Hopctt9o51lELXJOxQnFg8m0Tos6-PwqkiX4pS0aPTT9Qt4Hb6GpUWxg#gid=1234077870 He's since gone and added some capacitor comparisons as well...

It's a pretty good go-kart, those hoverboard hub motors have outrageous torque. :lol: The odd XT60s are a little trickier to find, but the with thru-hole types you can just fall back to wire. I've used the right angle thru-hole XT60s and XT30s on a couple of my projects and they've worked...

Yup, Cambridge, I'll get our mutual to poke you. He's been raving about H7s and though he might have got you. Have you looked at the XT60PB or XT60PW or XT60PT for power input connectors? IF you think you'll do more than 60A cont then the XT90PB/XT90PW would be the next step up.

I bet I know the guy who suggested the H7 to you! I quite like Molex PicoBlade, I just buy the 30cm pre-crimped wires, easy to cut in half and then wire in.

Why does every brushless ESC need to be eBike compatible? I like what mxlemming has done here with his ESC and I agree, keep it a simple speed request input and let another board handle the eBike restrictions. Also which countries restrictions? And when those restrictions become stricter or...

One of the advantages of IMS is you get to double the effective copper thickness, so 3oz IMS is equivalent to 6oz FR4. One big advantage of that is you don't have to worry about larger track & gap allowances that higher copper thicknesses push you towards. You're always going to have to run...

with respect to IMS power stages I found PCBWay was letting you specify a 2 layer, 3oz (105μm) per layer, IMS PCB for not wildly more than a single layer. By putting both layers on the top side of the aluminium you'd get approximately 100μm spacing between the copper making for a low inductance...

And they're terrible.

Do you have dissipation numbers for the TO-264 package? I wonder how easy they'd be to add to this form factor.

No. VESC6 is good for 80A, not 500A.

That wouldn't be the hardest thing to do, nothing like driving the motors really.

Hi, I've been using VESCs to control 6kW BLDC motors but have had to current limit the motors quite severely to avoid damaging the VESCs. I've been planning to make my own and was wondering if a Lebowski MCU would work? I'd want: bidirectional control control via PPM, also known as servo...
