GITech, no i don't know about revolt new series, and i do not want use them anymore as we have dev. own motor and it works muuuch better for specific mid-drive ebike.
Not shure that i'm gonna change FET in the near future, as this may lead to some scheme changes.. However i'm gonna develop extreme small 6F version on 75V FET
Yep. Nucular controller :)

In the russia board there are more infos about the BMS

https://electrotransport.ru/ussr/index. ... msg1304677

some features (translated text):
16S 50A 65 * 100mm
battery heating, 4 temperature sensors, CAN bus, there is still a small built-in display, smooth start, 12 volts is
made for quick-release battery
soft in development. autonomy - yes. programmability - yes. Watch the tapestry voltage - yes

other configurations still in development

Controller month~two for www sale, motor needs some investments to start production :P
Bare motor 2.2kW nominal, 2.8kg, 50mOhm for 48V @ 3000rpm, inranner, air cooled. How much this can do in boost i don't know, for almost continious 2kw it stays cool (hill climbs on bike)

Even if there is high demand, plenty of inquiries etc, you should allow enough time to develop at least the hardware part to the end.
I am not saying there are any issues :) , just were thinking about the Ada**** case.

Congratulations and good luck with your controller/bms. Would it be possible to have some basic dimensions for the proposed motor. The specs sound very promising and you clearly know what you are doing.

Thanks very much for the speedy reply. Perfect size for ebike packaging. from the information earlier in the thread I make it about 70kv and 5ish Nm.

Thanks very much for the speedy reply. Perfect size for ebike packaging. from the information earlier in the thread I make it about 70kv and 5ish Nm. Just checked out Instagram. Looks great, room for a strong axle, plenty of cooling fins and a 3d fan. Look forward to more updates.

The feature with the constant speed if battery becomes discharged is nice.
And i like that this controller is compatibile with low resistance / inductance motors due to the low inductive power stage together with ultra quick measurement of currents.

Congratulations, must take a lot of hard work and time to configure these features. Very innovative for the hobby market. I look forward to purchase and testing.

No problem. Take you time and make it right from the start. You got a lot of people rooting for you here on ES, and we want to see you succeed. Worst thing would be to rush this project to meet the market. Just take your time, do it right and I am sure you will get plenty of support and customer your way.

Great video with lots of nice new features.

Did I miss the pricing on this one or what your thinking to start?

Excellent looking device.

Nice features set!
How is the FOC only behaviour at loaded start?
What happens in sensor or combined option if hall sensor fails?

Nice start
Currently FOC only sensored, later i will add sensorless FOC also
For square you can switch to sensorless

What kind of FETs do you use? I assume they're all N-channel. 200 amps for 30 seconds sounds very nice, even across 2 FETs.

And for the over-regen protection, I'd just put a thermistor next to the FETs and dial back the regen if the FETs got too hot.
When in doubt, get bigger MOSFETs!
