Modelling torque vs speed curve of motor

Omniverse Isaac Sim
1

Motors have full torque at zero velocity and zero torque at maximum velocity. This affects a robot arm’s performance.

Is there any way to model this using Isaac Sim / PhysX? Would a custom controller where I reduce the applied joint force as the joint velocity rises work?

Thanks,

Yes, modeling your own and applying corresponding joint torques is your best bet. We don’t have a native electric motor model in PhysX.
