AC Dynamometer Drives

AC Regenerative Drives

Regenerative AC drive systems, also known as four-quadrant drives, are capable of controlling the speed and direction of AC dynamometer rotation, as well as the direction of AC dynamometer torque. Regenerative AC drives provide the AC Dynamometer with the ability to both absorb power and motor the device under test. 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 drives can reclaim a majority energy produced from the device under test which can reduce the overall cost of testing.

AC Non-Regenerative Drives

Non-Regenerative AC drive systems, also known as two-quadrant drives, are capable of controlling motor speed and torque in one direction only. Typically, 2-quadrant AC dynamometer drive systems are used to control an AC dynamometer that acts as a prime mover in a test stand. This motoring-only AC dynamometer may drive a device under test while controlling and measuring speed or torque.
