Big Rover - Big Motor (650W) - BLDC Motor Controller - Motor Action Problem

[Havas_Robotic]

Hello. I’m trying to do Big ArduRover. Equipment I use:
1-) 2 Pieces 650W Brushless Motor
2-) 2 Pieces 48-64 V / 1500W Brushless Motor Controller (Electric bike Driver)
3) 5 Pieces 12Volt 60Ah gel battery
4) Pixhawk Flight Controller
5) ArduRover 4.0 Firmware

I cannot move the 650W motor.
.
The other small motor (2205) is moving. (For testing)
.
I have no experience with Rover. I am considered experienced in ArduCopter. I tested the Motor and Driver. They work.
.
How can I run this type of motor and driver with ArduRover. I want to check with Cuav V5 +…
.
Thank you in advance for any help.

I tried it with Pixhawk mini. I tried PPM and Sbus protocol. Nothing changed.

That controller have pwm or analog signal?, I hope is analog, chek that.

@cala2 Thank you for your answer.
Normally it is controlled by the throttle handle like in the picture. 3 wires come out of throttle handle.

Yes thats a common analog potentiometer 0-5v, pixhawk need a pwm signal, you need to convert or use a potentiometer move with a servo

@cala2 Thanks to you, I understood the problem clearly. I think it will be a Mechanical transformation that you are talking about. Can it be used stably with ArduRover? Or do you have any other driver suggestions? This vehicle should be able to act autonomously.
.
Since it is a brushless motor driver, what is the probability of converting the Analog signal to PWM inside. If I open the drive inside, can a solution be found?
.
Thanks

Hi,
I solved the same problem with: PT01B - https://www.aliexpress.com/item/32894100377.html?spm=a2g0s.9042311.0.0.27424c4dNQhpV9
Settings MOT_PWM_TYPE : 0 ,
if you use MOT_PWM_TYPE 3, another converter is required.

I starting a similar proyect than you, Im not an expert but I hope that you cant, Jiri solution looks the best if you can buy it, (I have customer restrictions but try to find here ) I read that a low pass filter do the same job but I dont try yet. Nice frame Im going to share my work when I advance a bit.
