Description
Eddy Current Dynamometers (Dynos) Providing Precise Control and Low Maintenance
The E-20 Series eddy current dynamometers build upon the trusted legacy of the DM-2025 family within our DM-Series product line. These dynamometers deliver reliable precision and performance for a wide range of applications, including engine testing, electric motor testing, and other torque measurement needs.
Carrying Forward a Legacy of Innovation Since 1931
Continuing the tradition of the renowned DM-Series product line, the E-20 Series builds on the legacy of the Dynamatic brand, established in 1931 with the introduction of the revolutionary eddy current clutch. Since then, Dynamatic has consistently led the way in developing innovative drive and control systems. Notably, it pioneered the industry’s first self-contained drive unit that combined a motor with a variable speed clutch. This long-standing spirit of engineering excellence is clearly reflected in the E-20 Series, which is specifically designed to meet the high demands of today’s industrial applications for performance and reliability. Moreover, the name “Dynamatic,” a fusion of “Dynamo” and “Automatic,” continues to represent quality and forward-thinking in variable speed control, core values that the E-20 Series proudly carries forward.
Whether you’re experienced with the DM-2025 family or specifying a new test system, the E-20 Series offers the durability, accuracy, and reliability you expect from a longstanding history of eddy current dynamometer expertise.
