How to get Max Torque at start

Hello

I am desesperatly wondering how to get max torque at start. My motor can get up to 80A and is sensored (5065 270KV). The battery (6S 45C) can deliver them. I don't know why the VESC limits it to 45A after the wizard process and when trying to run it limits to 35A. With another motor it delivers 50A but this motor is twice as heavy as the one I wan't to use and that can deliver the torque. I am using Flipsky VESC4.2 (so 50A max).

What should I do in the configuration to get hte max torque ? I tried to reduced or to raise the positive Ramping time : it doesn't change anything.

 

Any ideas ?

Thank you all

Did you ever get anywhere with this? I'm looking for for more low speed torque. Cheers

Hello. Finally I moved to BLDC control : everything works perfectly. I recommend to use BLDC instead of FOC (FU CK) control ;-)

I admit that I have not tried low speed control. But for sure it should work as BLDC is watching for sensors and then command the coil according to them

I have a nother pb : I use ADC1  to have 2 different speeds. when full voltage 3.3V on ADC1 it works and gives full speed at full power. when lower tnesion (the measure is ok) but it goes directly to full power. What should I do  to be able to adjust the speed using ADC1 ? What is wrong with my VESC parameters ? Thank you

Would like to know this answer too? No power off the line on foc mode and bldc just binds up on vevor motor?
