High Speed Test Benches and Dynamometers

Burgi Engineers LLC is your most reliable choice when it comes to custom and high performance AC motoring and absorbing test stands. Because we design the motors used in our test stands we have a complete understanding of the product, from the materials being used to the fit between rotor and shaft. Among other things, we know the electrical design, natural frequency of the rotor, bearing stiffness values, rotor yoke stress levels, and heat transfer data for various parts of the motor.

This unique perspective allows us to push these machines to their limits and grants us the ability to consult with you on options that other system integrators and motor manufacturers do not recognize or understand.

Thanks to modern variable frequency drives (VFDs) we are able to design and build test stands that deliver a specific torque to speed profile. With closed-loop operation very accurate control of speed and torque can be achieved. Utilizing the proper control methods, combined with power-dense low‐inertia motors we can create highly responsive machines which simulate real-world load profiles.

We offer touchscreen-operated control and monitoring systems for the test stands as well as for the test articles. We have vast experience designing robust machine bases, to dampen vibrations in your applications (our largest cast and machined bases weigh over 4 tons).

Our supporting cooling and lubrication systems are uniquely designed to enhance our motors and deliver peak performance from these test stands. Ultimately Burgi Engineers LLC offers you the ability to purchase a world-class turn-key package from the same engineering firm who designed the motors going into your test stand.
