Product Description:
The 07.09.670-4003 is an electromagnetic clutch-brake unit manufactured by KEB and assigned to the Combibox Clutch Brakes series. By magnetically connecting or interrupting torque between an input hub and an output shaft, it enables controlled acceleration, deceleration, and holding functions inside automated machinery such as packaging stations, feeders, and light conveyors. The Bore-In input arrangement accepts keyed hubs, while the Shaft-Out configuration provides a direct output stub for couplings.
This model delivers a rated clutch torque of 15 Nm, so loads up to that torque level can be engaged without slipping once the coil is energized. The permitted rotational speed extends to 3000 rpm, which is the maximum shaft speed for variable-speed operation. The clutch engages in 95 ms, while release is completed in 20 ms; these response times support precise indexing cycles. A coil consumption of 20 W keeps control-cabinet power demand low, and an additional delay of 25 ms separates electrical excitation from mechanical engagement to cushion the drive train. During emergency stops, the unit can absorb 3.1 × 10³ J of friction work. The friction linings tolerate repeated operation within this limit, and maintenance restores proper operation after the allowable wear level is reached.
Dynamic performance is influenced by a rotor inertia of 2.98 × 10⁻⁴ kg·m² and an armature inertia of 1.2 × 10⁻⁴ kg·m². These inertia values affect how quickly the connected load can change speed when the clutch-brake switches state. The working gap between the rotor and armature is factory-set to 0.3 mm; after wear increases it to 0.6 mm, the mechanism must be readjusted to maintain timing accuracy. Continuous heat generated by the sliding surfaces is limited to 114 J/s, allowing duty cycles to be calculated without causing thermal saturation. Each friction disc is rated for 16.3 × 10⁶ J of accumulated work before reaching a wear limit of 0.1 mm. This wear limit provides a measurable basis for scheduling service during repetitive automation tasks.
