I am sorry I did not provide all the information from the beginning. I understand what you mean.
Could you advise me an idea or possibility where to look for solutions. I've been stuck looking for an engine for quite a while now as I'm not sure. I will try to look for a 4 quadrant controller with torque control.
In case of using a servomotor would it be simpler ?
Thank you very much and sorry for the inconvenience
