An amplidyne is a form of electromechanical amplifier in which an AC motor drives a DC generator.

an amplidyne is usually an ac motor driving a dc generator with modifications to increase the power gain available. a small electrical signal can control the position of a large motor using this approach. an amplidyne is a special type of motor-generator, which uses regeneration to increase its gain. energy comes from the motor, and the power output is controlled by changing the field current of the generator. in a typical generator, the load brushes are positioned perpendicular to the magnetic field flux. to convert a generator to an amplidyne, we need to connect, what would be the load brushes together and take the output from another set of brushes that are parallel with the field. the perpendicular brushes are now called the quadrature brushes. this simple change can increase the gain by a factor of 10000 or more.
