Design Features
□The rotor and the stator are made of high quality magnetic materials. There is a gap between rotor and magnetic pole so no wear occurs during operation.
□Coils are made of single polyimide wire wrapped with glass fibre. The insulation level is Class H.
□The water cooling system ensures that the heat generated by the brake can be dissipated even under maximum load.
□Rotor shafts are supported on double-row radial spherical roller bearings.
□Eddy Current Brake is connected to the drum shaft by means of involute spline tooth clutch.
