Product Description:
The 07.10.670-SLA is an electromagnetic clutch-brake combination produced by KEB within the Combibox Clutch Brakes series. Installed between a driving motor and a load shaft, the unit couples or stops rotary motion on demand in packaging lines, indexing tables, and similar automation axes. Energizing the clutch transmits torque from the input flange to the output, while releasing it applies the integral brake so that motion halts quickly and repeatably. The compact Bore-In/Shaft-Out mounting style lets the module fit into enclosed gear trains without additional support brackets.
During continuous duty, the mechanism delivers a rated brake moment of 15 Nm, and the same torque capacity is available on the clutch side for synchronized engagement. Operation is permitted up to 3000 rpm, allowing direct connection to four-pole induction motors without overspeed. Initial magnetic clearance is set at 0.3 mm, and keeping this gap helps maintain consistent response times as wear occurs. The rotor contributes only 2.98×10⁻⁴ kg·m² of inertia, and the armature adds 2.62×10⁻⁴ kg·m². These low inertia values minimize speed sag when the clutch engages, which supports high-cycle positioning drives. A B5 (2) input flange mates with standard IEC motor faces, and a B5 (1) output flange transfers torque to gearboxes or pulleys.
The electromagnetic coils set the thermal limits: the clutch can absorb 20 W of steady excitation loss, and the brake is rated at 16 W. Energy generated at each stop must remain below 3.1×10³ J, a ceiling that protects the friction linings from glazing during rapid deceleration cycles. After wear reaches the service point, the working clearance is increased to the 0.6 mm readjustment gap so that torque remains within tolerance over the service interval. Clutch wear work over 0.1 Mm of actuation reaches 16.3 × 10⁶ J.
