Eddy Current Dynamometer. The Eddy Current Dynamometer is BI-DIRECTIONAL, DRY-GAP TYPE. In a dry gap unit, the only resistance to movement of the rotor is that of bearing friction and the small effect of windage. With zero excitation, an almost no-load condition can be achieved over the entire speed range.

    In an eddy-current dynamometer, the coil excites a magnetic field through one cooling chamber, the air gap with toothed rotor and the second cooling chamber. The magnetic flux lines close above the iron back. When the rotor rotates, the teeth continually rotate. The air gap varies due to the rotating teeth and gaps. The variation of the air gap continually changes the magnetic circuit and, by Eddy current dynamo meter used to measure engine torque and power. It works on the principle of eddy current generation that oppose the change in magnetic flux. Eddy currents are generated when a conductor moves in changing magnetic flux. Eddy cur...

    DYNOmite Air-Cooled Eddy-Current Absorbers offer very quick load control, moderate inertia, and high specific load capacity, especially in the lower RPM working ranges of most industrial-type engines. For applications that do not require stall-speed loading, an air-cooled eddy-current absorber is usually the most cost-effective electric absorber you can buy.

    Eddy current dynamometer: It comprises of a stator with some electromagnets and a rotor disc coupled with engine’s output shaft made of steel or copper. When the rotor is rotated, an eddy current is produced because of a magnetic flux set up by field current in the electromagnet. This eddy current is dissipated in generating heat, therefore 10/11/2017 · Construction and Working of Prony Brake Dynamometer, TOM, Mechanical Engineering, GATE Mechanical Engineering Video EduRev video for Mechanical Engineering is made by best teachers who have written some of the best books of Mechanical Engineering.
