Product Description:

The 06.09.670-4010 is a combined clutch-brake module manufactured by KEB as part of the Combibox Clutch Brakes series. It is intended for industrial automation tasks that require rapid engagement, disengagement, and holding of rotating loads under controlled torque. Mounted between a drive motor and driven equipment, the device transmits motion through its B5 (2) input flange with a bore-in coupling and delivers it through a B5 (1) shaft-out flange. This arrangement allows compact installation while supporting precise start-stop cycles in packaging, indexing, and conveying machinery.

During operation, an electromagnetic coil energized at 24 V DC draws only 15 W, so heat generation in enclosed panels stays low. When the clutch is activated, it reaches full mechanical engagement in 55 ms, allowing high-frequency indexing without noticeable lag. Once engaged, the friction interface sustains a continuous torque of 7 Nm, which is sufficient to hold moderate-inertia shafts against normal process loads. The assembly tolerates spindle speeds up to 3000 rpm. Operation above this limit could create centrifugal forces that reduce friction contact and shorten service life.

The kinetic behavior of the unit is influenced by an armature inertia of 0.80 × 10⁻⁴ kg·m² and a rotor inertia of 1.07 × 10⁻⁴ kg·m², which keep acceleration times short when the module is coupled to lightweight tooling. Thermal limits include a maximum friction rate of 81 J/s and a single-event friction work allowance of 1.9 × 10³ J. Staying within these limits helps prevent surface glazing during repeated stops. The initial working gap is set to 0.2 mm. As wear increases the gap, the readjustment clearance can be reset to 0.4 mm to restore proper operation. This adjustment compensates for friction-surface wear and helps maintain consistent engagement.
