Motor Constants

We are university students in South Africa and have an assignment to do concerning the rolling process of aluminium. We have to design a control system for the motor to make sure that the output thickness and speed are held constant. So, basically we are looking for motor constants for a 50 - 200kW DC motor.

The constants we need are the armature inductance, torque constant, armature resistance, rotor inertia, viscous friction coefficient.

Thanx.
