AC and DC Drive Integration Solutions

Offering regenerative and non-regenerative drive integration solutions that range from straightforward to complex systems for your testing application. We can also replace, upgrade, or retrofit AC or DC systems to meet specific engineering requirements.

Regenerative Drives

Capable of controlling the speed and direction of an AC or DC dynamometer’s rotation, as well as the direction of 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 drives provide the dynamometer with the ability to absorb power and motor the device under test. Regenerative drives when operating in the absorption mode, can reclaim a majority of the energy produced from the device under test which may reduce the overall cost of testing.

Non-Regenerative Drives

Capable of controlling the speed and direction of an AC or DC dynamometer’s rotation, as well as the direction of dynamometer torque. As a non-regenerative design, the mechanical energy absorbed by the dynamometer is converted to electrical energy which is then converted to heat energy inside a brake resistor.  The brake resistors can be air or water cooled depending on the facility needs and capabilities.
