Technical Specification：
The electromagnetic eddy current brake makes zero wear brake by taking advantage of electromagnetic induction principle and having the features of large torque,without replacement parts,long lifetime,simple operation and maintenance.It includes air blast cooled(DSF) and water cooled(DSW) Series.DSF is featured by compact construction,small weight,convenient maintenance; DSW is featured by high output power，slowly warming, powerful adapitive capacity to environment. It is an ideal auxiliary brake suitable for petroleum drilling rigs of onshore and offshore, and it could provide auxiliary brake torque of 23KN~110KN for 500m~9000m rigs. It is working temperature is -30℃~55℃.
