DC Dynamometer Drive

DC Regenerative Drives

Regenerative DC drive systems, also known as four-quadrant drives, control both speed and direction of DC dynamometer rotation, as well as the direction of DC dynamometer torque. The term “regenerative” describes the ability of the drive under braking conditions to convert the mechanical energy of the motor and connected load into electrical energy which is returned (or regenerated) to the AC power source. Regenerative DC drives provide the DC Dynamometer the ability to both absorb power and motor the device under test.

DC Non-Regenerative Drives

Non-Regenerative DC drive systems, also known as two-quadrant drives, are capable of controlling motor speed and torque in one direction only. Typically, they are used to control a DC dynamometer that acts as a prime mover in a test stand. This motoring-only DC dynamometer may drive a device under test while controlling and measuring speed or torque.
