Product Description:

The 0710670-003J is a combined electromagnetic clutch and brake module produced by KEB within the Combibox Clutch Brakes series. The unit is intended for inline installation between a driven shaft and a load, allowing rapid engagement or deceleration in automated machinery. By switching coil power, the clutch couples torque for motion, while the brake holds or stops the load. Because both functions are housed in one module, the unit can drive a load and stop it without using separate standalone components. This arrangement suits indexing tables, packaging actuators, and other machines that need repeated start-and-stop cycles in a compact drive train.

During operation, the clutch section can transmit a rated torque of 15 Nm and dissipate friction energy at 114 J/s, drawing 20 W of coil power when energized. The brake section holds the same torque level, releases friction energy at 80 J/s, and draws 16 W during operation. Both elements share a mechanical limit of 3.1 × 10³ J for single-shot friction work, while cumulative wear to the 0.1 mm adjustment point is 16.3 × 10⁶ J. The rotor may run up to 3000 rpm, so the motor side must also match the B5 (2) in / B5 (1) out flange arrangement and the bore-in, shaft-out mounting layout.

The unit has an armature inertia of 2.62 × 10⁻⁴ kg·m² and a rotor inertia of 2.98 × 10⁻⁴ kg·m², which influence acceleration and deceleration when the clutch or brake is applied. To maintain proper clearance, the assembly is supplied with a 0.3 mm operating air gap and allows readjustment up to 0.6 mm before the wear limit is reached. The flange arrangement supports coaxial installation with compatible motor and load components. Keeping the air gap within this range helps preserve consistent engagement and release behavior over time.
