Module DL 2681 represents a
process for the control of the speed of a dc motor.
In this module an electric motor and a generator are coupled through a flywheel in order
to increase the momentum of inertia of the whole system.
A motor speed transducer provides a feedback digital signal; through a D/A converter such
signal is available also in analog form.
