Eddy current system
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 … WebNov 26, 2024 · Eddy Current Damping. Eddy current damping is the most efficient form of damping. It is very convenient to use in instruments where a metallic disc or a former and a permanent magnet already form part of the operating system eg: PMMC instrument. For these reasons this method is used in hot wire, moving coil and induction type instruments.
