Re: Axiom: a 100kW+ motor controller

I hope the race went well Abricosvw, I just wanted to highlight here a couple of updates: hi i'm still alive ...the race was not very good rain ... I'm a little busy with school and work in the garage ... but I think at the end of September or October I will return to full time again ... but if any...

Re: VESC controller: Check Axiom datasheet!

what do you think when we can start use IPM motor ... You can give it a try anytime without Max Torque Per Amp. The motor should spin, it just doesn't use the reluctance torque. If you feel brave you can build the VESC Tool guI and use a firmware built with MTPA support from the testing branch. I c...

Re: VESC controller: Check Axiom datasheet!

How to calculate current gain of current sensors. HASS-400-S And after making all connections fault light is staying on. What could be issue. We have a lot of math developed around this controller to calculate gains, tolerances, trips, cutoffs, and errors, but that is not open source, its there to ...

as i know the magnets are inside the rotor ...and this is so that if they break then they remain inside the rotor in the same position ...the only difference is their geometric arrangement ...Tesla on model 3 uses Halbach Magnet style New Bitmap Image (15).jpg New Bitmap Image (12).jpg Pub26762.pdf

Re: VESC-controller

About that 5v difference, I wouldn't worry too much, if your fullscale is 600V, you have <1% error, and these isolated amplifiers have a rather poor offset spec. One thing you can try is using AMC1311, they work better for voltage sensing, you need to change the resistor divider because they have g...

Re: VESC-controller

Hi marcos I like your suggestion for 300a ECONO igbt's but the main problem i am facing currently is cost of production. One igbt is costing around 200$ x 3 = 600$ . And the beefy dc link capacitors costing around 500$. And also the size of controller will get so big to fit into e bike with 8kw bat...
