WebThe Eddy current dynamometer is a special device compared to the regular dynamometer. It has very low loss, high efficiency, and is more versatile. In the Eddy current dynamometer, the reason for the loss reduction is that there is no physical contact between the windings and the excitation. This has many uses due to its small size and combability. WebEddy current drives are slip-controlled systems the slip energy of which is necessarily all dissipated as heat. Such drives are therefore generally less efficient than AC/DC-AC conversion based drives. The motor develops the torque required by …

WebIDEAL Eddy Current Variable Speed Drives use constant speed electric motors and a DC magnetic field to reduce speed and generate incredible amounts of torque effectively. Our drives are intended to move high-inertia loads that frequently start and stop more efficiently than variable frequency drives (VFDs) are capable of. This incredible efficiency greatly …
