Product Description:

The 06.10.570-2DCU clutch-brake module is produced by KEB within the Combibox Clutch Brakes series. This unit combines an electromagnetic clutch and brake in a single housing, allowing machine builders to engage or hold a shaft from one drive end while keeping the other side motionless. In automated packaging, indexing tables, and light conveying equipment, the module provides controlled start-stop cycles without requiring separate mechanical couplings.

The device is energized with a standard control voltage of 24 V DC, so it can be driven directly from common PLC power supplies. When the clutch is activated it draws 15 W to magnetize the friction disc and transmit motion, delivering the rated clutch torque of 7 Nm; the brake section consumes 12 W and supplies a holding capacity of 7 Nm when de-energized. The assembly supports rotational speeds up to 3000 rpm, matching small servo and induction motors in light-duty stations. Reliable engagement depends on a factory-set working clearance of 0.2 mm, which helps maintain repeatable magnetic force while limiting residual drag between the discs during cycling.

During cyclic operation the friction linings can absorb up to 1.9 × 10³ J per single stop without exceeding thermal limits, while total clutch life is based on a cumulative friction work capacity of 9.5 × 10⁶ J. Wear increases the operating clearance, and once it reaches the prescribed 0.4 mm service gap the armature should be readjusted to maintain response times. Dynamic balance is aided by the rotor’s moment of inertia of 1.07 × 10⁻⁴ kg·m², complemented by an armature inertia of 0.84 × 10⁻⁴ kg·m² for low-inertia drive trains. This low inertia helps the module respond quickly during repeated starts and stops. The module weighs 2.8 kg, and the mechanical interface follows the B5 (1) flange with shaft-in and shaft-out geometry, allowing direct installation between an input motor and a geared reducer without additional couplings.
