-The rotor and the stator are made of high quality magnetic materials and subjected to heat treatment. 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 firbre and are dip coating of vacuum pressure in twice. The insulation level is class F or H.
-The cooling water is supplied by a circulating water pump to ensure that the heat generated by the brake can be sissipated even under maximum load.
-To connect with the drum shaft by involute spline tooth clutch
