Product Description:

The 07.10.370 is an electromagnetic clutch-brake unit produced by KEB within its Combibox Clutch Brakes series. Mounted between a driving and a driven shaft, the module engages or halts mechanical power through controlled magnetic fields, allowing timed indexing, emergency stops, or dwell cycles in automated machinery. By integrating a clutch and a brake into one housing, it simplifies drivetrain layouts and reduces alignment work in conveyors, packaging stations, and similar motion sequences.

The clutch section draws 20 W from the control supply to establish its magnetic field, while the brake requires only 16 W to hold the rotor stationary. When energized, the clutch transmits a rated torque of 15 Nm, matching the brake torque so that acceleration and deceleration forces remain symmetrical. The assembly can spin at up to 3000 rpm; beyond this speed, excessive surface velocity would shorten lining life. A supply of 24 V DC fits standard machine safety relays and minimizes coil heating. Proper engagement depends on keeping the working air gap close to 0.3 mm. As the linings wear, set screws are advanced to maintain this clearance and preserve response time.

Dynamic behavior is influenced by the armature disc’s inertia of 2.62×10⁻⁴ kg·m², which affects how quickly torque changes translate into rotor speed changes. Energy absorption per stop is limited to 3.1×10³ J, so duty cycles must stay within the unit’s thermal capacity. Overall mass is 3.9 kg, which is light enough for foot mounting on small gearboxes while still providing rigidity. The unit uses a shaft input, shaft output, and a foot-style base to simplify installation. A readjustment clearance of 0.6 mm supports continued service life when the linings approach their wear limit. The rotor’s own inertia of 2.98×10⁻⁴ kg·m² and a maximum clutch friction rate of 114 J/s further limit permissible start-stop frequency.
