Water / Coolant Cooled Eddy Current Dynamometer is ideal for testing engines and motors in medium and high- speed range and in machines with turbo characteristics. Application Systems manufactures Water / Coolant Cooled Eddy Current Dynamometer. Application Systems also manufactures Powder dynamometers, tension controller and load cells. Water / Coolant Cooled Eddy Current Dynamometer comes with the power absorption of 20 W to 750 KW. The medium of torque transmission in Eddy Current dynamometers is a controlled magnetic field generated by a stationery coil. The developed torque in these dynamometers diminishes with reduction in speed with no torque developed at zero speed.
