Key Features

AccuDyne dynamometers offer completely seamless crossover between motoring and loading modes, providing true simulation of real-world, in-use events. These dynamometers are not only versatile and able to meet challenging testing conditions, but they are also highly accurate and energy-efficient.

Fully Regenerative

Fully regenerative capabilities allow power to return to AC mains, saving energy costs significantly compared to brake-based dynamometers. Non-regenerative options are also available.

Precise Speed and Torque Control

These dynamometers offer full torque to zero speed control while providing exceptional accuracy for torque measurements (0.05 percent full scale typical, 0.01 percent optional).

Overload Capabilities

Up to 200% overload capability allows the dynamometer to be sized for continuous power, rather than brief transient events.

Special Options and Models 

At SAKOR Technologies, we specialize in creating dynamometers that meet our customers’ specific requirements, and we have developed a variety of dyno models for specialized applications. These and many other unique configurations allow the AccuDyne to meet challenging testing requirements for cutting-edge devices.

Tailored Base and Bedplate 

Special configuration of the base and bedplate allows the dynamometer assembly to tilt up to +/- 90 degrees with up to +/- 90 degree CW/CCW dynamically rotating DUT mounting fixtures.

Torsional Pulsation and Engine Simulation

Easily test drivetrain components, such as starter/alternators, transmissions, gearboxes, clutches etc. without the need for a full engine test cell.

Flexible Configurations 

We offer optimal solutions for very low speed, very high torque, and very high speed applications. Additional variations are available to test ultra low inertia, ultra high acceleration conditions, and more.
