Product Description:

The 07.10.440-0000 is an electromagnetic clutch-brake unit produced by KEB within the Combibox Clutch Brakes series. It combines a friction clutch and a spring-applied brake in one housing, allowing a drive to engage or hold a load without separate components. In automated machinery, the device sits between the motor and the driven shaft, providing rapid torque transfer for indexing and secure holding when power is removed. Its combined layout also reduces the space needed for separate torque-transfer and stopping components in compact drive assemblies.

During clutch operation, the coil draws 20 W, while the brake circuit requires 16 W. These low input levels let control cabinets use simple 24 V supplies without heavy relays. Both the clutch and the brake deliver a rated torque of 15 Nm, so the same housing can transmit or stop identical load levels. The unit is designed for shaft speeds up to 3,000 rpm; above this limit, the friction surfaces can overheat. Energy absorbed per stop is limited to 3,100 J, which helps determine the allowable stopping frequency during repeated cycling. A B5 (2) input flange with a bore-in hub accepts the motor shaft, and the opposite side uses a plain shaft output because no output flange is fitted.

Dynamic behavior is governed by two inertia values: the armature at 2.62 × 10⁻⁴ kg·m² and the rotor at 2.98 × 10⁻⁴ kg·m². These values help match acceleration profiles and reduce shock loading during engagement. The working air gap is set to 0.3 mm, and wear adjustment to 0.6 mm restores response time as the friction surfaces age. The windings use ISO Class B insulation, supporting coil temperatures up to 130 °C in continuous duty. This arrangement suits conveyors, packaging stations, and other motion axes that need compact engagement and holding functions.
