Product Description:

The 09.10.370 is a clutch-brake combination unit produced by KEB within the Combibox Clutch Brakes series. This electromechanical module couples and decouples torque on a shared shaft to coordinate start-stop cycles in automated machinery. By integrating a clutch and a brake in one housing, the unit simplifies drivetrain layout and allows rapid indexing of conveyors, packaging stations, or positioning tables.

At 20 °C, the clutch coil absorbs 35 W, while the brake coil needs 28 W, and the additional power in the clutch winding shortens energization time. Both sections are designed for a rated brake torque of 65 Nm, and the rated clutch torque matches this figure. During cyclic operation, the brake can dissipate 164 J/s of thermal energy, whereas the clutch is allowed 228 J/s. Proper separation between rotor and armature is held by a rated air gap of 0.35 mm, and initial setup within this value supports consistent torque with minimal drag. Control voltage is standardized to 24 V DC, so the unit can be driven directly from common PLC I/O power rails. The shaft-in/shaft-out configuration simplifies inline mounting without pulley or belt stages.

The dynamic response is influenced by a rotor inertia of 0.002329 kg·m² and an armature inertia of 0.002308 kg·m², giving balanced acceleration characteristics for drives up to 3000 rpm. Energy limits include a maximum friction work of 7.5 kJ per single engagement and a cumulative clutch work rating of 40.9 MJ measured to 0.1 mm lining wear. When the wear limit is reached, the air gap can be restored by resetting the mechanism to the 0.7 mm readjustment gap. The unit uses B5 (1) / B5 (1) flange faces, allowing direct coupling to IEC motor and gearbox housings without custom adapters, and the inline shaft arrangement maintains concentricity throughout the drivetrain.
