Mechanical Simulation for Universal Motor Operated at AC

I want to simulate variable load condition on the Universal motor. This universal motor is connected to gears to reduce the speed. This mechanism actautes a linear movement.

Now I want to simulate a load condition on this motor so that as it goes away from the initial position the power required by the universal motor increases and when the final position is reached the supply is stopped.

To simulate this, is it OK to use a DC motor (where I is directly proportional to Torque in the initial operating region) so that I can vary the current through a controller and achieve high torque as the distance increases.

Please let me know about this.

Thanks.
