Powder Dynamometers

powder and magnetic dynamometers develop torque on the basis of electro-mechanical principles wherein the torque developed is independent of speed. The braking torque is infinitely adjustable through the medium of fine magnetic powder under the influence of the controlled magnetic field. These dynamometers are ideal for testing motors from zero speed, transmissions and machines demanding high torque at low speeds.
· set torque is fairly stable right down to zero speed
· speeds of operation up to 3000 rpm, depending on the model
· low inertia, dynamically balanced rotors 
· low residual torque as specified for each model
· available in water-cooled models
