How to calculate torque and speed.

[mkanon]

We are planning to build a 2dof platform this is our inspiration:
http://www.motionsystems.eu/products/mo ... -platforms

We're trying to replicate the dimensions, but are still looking for the perfect motors..

We found the plug and play motors from nanotec
http://en.nanotec.com/products/229-pd6- ... g-control/

RS485 interface (we are going to connect the sim to Unity3d (game engine) do develop our own games..)

But we are sill struggling with two variables.. Torque and speed.. is higher better? the most expensive motor is still in our budget (is you follow the link and click the motors you can see the torque/speed)...or could you have to much speed and torque? if we buy the fasted highest torque engine, can't we simply configure it to run slower...Or am i thinking to easy here?
