Baluncore my friend, thank you for taking your time to answer my questions! I can't describe how thankful I am, you totally made my day :). This is my first big modelling project and I had big doubts in my model, but now that I got your answers I'm more confident about it. Altough I've...

https://imagizer.imageshack.us/v2/524x338q90/840/t1ds.png So this is the first DC-motor, attached to a shaft with inertia L. b is a frictional constant, k_T is a scaling factor between current and torque. k_w is a scaling factor between voltage and angular velocity. T_L is load torque and...

First of all, thanks for answering, despite the poor description. To make things clear, this is an already existing system that I want to model and be able to simulate. I'm using Simulink to do that. UltrafastPED: yes I have two PID-controllers, one for each motor, i.e. one of them controls the...

Hello guys! I'm trying to model two shafts connected to each other by gears. I have two servo-controlled DC-motors, one on each shaft and I want them to work against each other. 1) I want to keep the angular velocity of Motor1 constant, so that the angular velocities of the two shafts are...

Thank you guys, now I understand better! Appreciate it a lot! :)

I just found out that the "total torque" will be 0 due to the constant angular velocities. There will however be an internal torque. This internal torque is generated from two motors (connected to the two shafts) working against each other. But I still don't know which extra formula to use. I'm...

Hello guys! I'm trying to model a simple model of a driving shaft connected to a rear axle. The axles are connected to each other by a pinion and crown gear. However this isn't any problem to model. My problem is that I want the driving shaft to rotate at a constant angular speed and then...
