Comprehensive Dynamometer Design and Service
Dyno One considers itself the industry leader in the supply of dynamometers and complete test systems. With a large selection of new and many remanufacturing options, including complete repair services, lease options and upgrades to existing equipment, we are able to provide a comprehensive offering in sales and support for a wide variety of application specific solutions.
Engineering Services
Dyno One can design and engineer systems that work for you. Our in-house engineering team has designed dozens of systems, including fluid systems, exhaust systems, air systems, drivelines, and more. designing a system that works for you and the ability to manufacture that system as well.
Repair, Remanufacture & Upgrades
We repair and rebuild nearly every make and model of eddy current, AC, DC and water brake (hydraulic) dynamometer. We work with a wide range of dynamometer brands, including GE, Midwest, Eaton, Dynamatic, Schenck, Borghi & Saveri, Froude, Hofmann, Horiba, Meiden, Zollner, AVL, SAJ and many more.
Service Parts
Dynamometers can operate to specifications for many hours under the right conditions, but over time will require parts replacement. Dyno One provides new OEM and high-quality replacement parts for many different makes and models in addition to our line of SR, TR and LI Series units.
On-Site Services
Our highly trained technicians can provide on-site services such as laser alignment, portable balancing, troubleshooting and analysis and predictive maintenance monitoring. We can also assist in helping to put into place an effective maintenance program that allows you to get the maximum service life and performance out of your dynamometer systems.
Dynamometer Testing Products
Dyno One’s dynamometer systems and software are designed and built in the United States. We are continually adapting our systems to serve the most innovative markets and solve the most complex testing challenges.

Dynamometers
Dynamometers are the core of many testing systems. We provide a wide variety of dynamometers, including AC, DC, EV, Hub, Inertia, and Eddy Current water brake systems. We are also able to combine and customize these systems to suit your needs.

DynoLAB™ GenV
DynoLAB™ GenV Test Automation Controller automates performance, development, durability, and quality control tests, including complex in-use and road load driving cycle simulations. It is easy to use and capable of ongoing unattended operation.

Motor Efficiency Test (MET)
Dyno One provides electric motor efficiency test stands that perform in accordance with a variety of national and international standards. Our systems can test 2- to 8-pole motors ranging from 10 watts to 2 megawatts for a range of applications.

EV Battery Test Systems
Our EV Battery Test Systems make it easy to conduct research and development, performance evaluation, and durability testing of high voltage power systems and EV batteries of all types.

Battery Simulator
Proper battery testing means testing under various conditions. Our technologies allow you to put the battery through demanding conditions and varying charge states.

Control Products
We provide digital closed loop controllers for AC, DC and Eddy Current Dynamometers. With a variety of integrations and features, users can easily access and determine torque, speed, power, in a way that works best for the application.
Dyno One Projects
With over 35 years in business, we have shared our experience with the world’s brightest engineers at the most advanced companies. We tailor dynamometer testing systems for common testing challenges in everyday products, as well as the most advanced challenges in space exploration, alternative energy, and more.
7,000-95 HP Natural Gas Engine Test Cell
The CAT. Remanufacturing facility in Corinth MS. Desired to expand test capabilities. The goal was to construct a new test cell with infrastructure and equipment capable of testing engines from to 7,000 to 95 hp using both diesel and natural gas fuels. Dyno-One provided engineering studies and project support throughout the designing, construction and integration process of each system. Upon completion, “Test Cell #6” was able to successfully test a greater range of engines than any other test cell has previously been capable of in the North American Market.
New 750 HP AC Dyno
Achates Power required a new 750 hp AC dyno for engine development. Dyno-One designed, manufactured and supplied the dyno motor and mechanical equipment required while also integrating customer supplied equipment. The system included a spindle block with a flex disc shaft coupling to isolate the engine drive shaft from the dyno and the in-line torque transducer. Dyno-One delivered the system as an assembled package allowing smooth integration into the customers’ existing facility.
Low Inertia Offset Hybrid Dyno
The Cummins tech center in Charleston, NC required expanded capabilities for engine testing. A dyno was required with minimal inertia to allow for low speed and varying test cycles while still allowing peak power test capability. A 100 hp ac motor was used to counteract the large inertial forces of the eddy current dyno, while allowing continued use of the eddy current dyno’s large power absorption capacity. Additionally, when not needed for inertia offsetting, the 100 hp motor can regenerate its full power capacity, partially offsetting power consumption of the test stand.
