Oh, its not an earth-shaking feature, don't worry. The focus now is in the packaging so we can offer more than a populated OSH pcb. No release date, I want it now so we can sell and fund more development, but its not that easy, lots of things can go wrong in the prototyping.Nice job Marcos looks good! Any release date prevision for the future magic?
Looks like the usual sort of free energy bullshit artist, displaying results with huge emphasis on one variable to appear impressive.dmann wrote: ↑Apr 08, 2018 2:00 amMarcos what if Youtuber Gerard Morin is right, that these larger drum motors work best with higher voltage + higher frequency rather than higher current? How easy would it be to modify to have lets say an output of between 240-500volts and a frequency range between 15khz - 25khz. In one of his last two videos he is getting what seems to be a tremendous amount of torque from less than 1 amp draw! Surprisingly I have not found other individuals working on anything like what is described. There is one company (Elmo) that has a controller for high voltage (Drum HV). There is also a company (un-named) making large manned drones in Isreal utilizing such technology. Any thoughts? Can higher volt lower amp mods be made easily on the VESC?
Good to know... Keep me updated. I'm keen to get this started but have a few things to do (including a holiday/trip) before I can start testing with the Controller. Basically, once the controller is tested with a 5kw motor I will be purchasing the motor for the vehicle and there's not much left to prep for that. If I get to the point where I need the controller to continue I'll get the boards made and order the parts... you can then have some more bench testing with a 5kw and >100kw motor... I do like the Vesc and am eager to see how this runs on a larger motor.marcos wrote: ↑Apr 09, 2018 7:10 amShaharov, I still don't have any spares left, I was ready to hit the big red "MFG" button and 2 customers resumed testing with >100kw motors and now I want to have their setup tested at full power before making new batch, these are expensive builds and any extra test is very valuable given how scarce test benches are. Last week I found 1 very minor issue in the hardware, and there is an ongoing firmware bug with rotor position algorithm.
My BOM says $1251, but it ignores many shipping charges, taxes, custom enclosure, bolts, connectors, cable glands, busbar assembly, manual labor and testing, so its hard to tell at this point.How much the whole assembly cost with controller
board,resolver interface ,DC link,igbt and gate drivers & heatsinks
