I am developing a wearable robot. After stimulation and dynamics analysis, I determined the required torque-velocity during the trajectory in the actuation unit motors' output (in my case, twisted string actuation unit or TSA). The torque is the load torque, and I know that the motor adds dynamics terms to the output torque.

I check some famous electrical motor creators like Maxon, but I can't find a matching motor for my need-based attached figures. I can do a trade-off between the motor's torque and velocity in my design, but I should select high-speed and low-torque motor matched to my need.

How can I find the best motor for my need based on the torque-speed figures during a trajectory?
