The electrical servomechanisms for DC motors are widely used nowadays in several different applications

Versatile as concerns the position controls, e.g., they are employed mostly in machine tools, where high precision relative motions between the tool and the place to be machined are required.

The board mod. G36A/EV has been designed and carried out to be an instrument necessary to the training of technicians with a high level of knowledge on DC motor controls.
