Operating Principles 

The DFK series clutch-brake combination is uses in situations where there is synchronous operation. The combination consists of DRK current applied clutch and DAF series current applied brake. When the DRK series clutch is de-energized, the shafts rotate independently of each other. When energy applies to the brake coil, the coil becomes an electromagnet, which creates a magnetic flux. This magnetic flux ensures the pressure flange to pull towards the brake coil, allows shaft and armature to rotate at the same speed. Thus come true torque transmission. When energy is applied to the coil of the DAF series brake, the coil becomes an electromagnet, which creates a magnetic flux. This magnetic flux ensures the pressure flange to pull towards the brake coil and braking. When de-energized the lamella spring, which is connected to the pressure flange, separates the pressure flange from the brake coil and ensures finish the braking.

Assembly Applications

F Type Combination



F type combination is a combination type that current applied clutch and current applied brake are in one body. In this combination, the desired torque transmission or braking occurs by energizing or deenergizing according to the operating state of the system. Torque transmission occurs when the clutch is energized, braking occurs when the brake is energized. It is used in applications that operate with high operating frequency and require precise positioning.

K Type Combination



K type combination is a combination type that there is only a current applied clutch inside the body. There is no brake in this combination. It provides to transfer the movement of one of the independent shafts on the same axis to the other shaft. When energized, torque transmits; when de-energized, the clutch disables.

D Type Combination



D type combination is a combination type that current applied clutch and permanent magnet brake are in one body. In this combination, initially both of the brake and the clutch are energized, thereby disengaging the brake and enabling the clutch to engagement. According to the operating state of the system, torque transmission performs when energized on the clutch and brake sides. When de-energized, the clutch disengages and the brake activates.
