Product Description:
The 07.03.10C-0241 is a spring-applied electromagnetic brake produced by KEB and supplied within the Combistop Spring Brakes series. This device is installed on servo or induction motor flanges to provide a fail-safe holding action whenever supply power is removed, preventing unintended shaft rotation during standby or emergency stops in automated machinery. It releases when energized and locks when de-energized, which makes it suitable for vertical axes, conveyors, and positioning tables where load security is mandatory.
The brake coil is designed for a nominal supply of 24 V DC, and at 20 °C it draws 0.83 A, equating to a thermal input of 20 W. Because the copper winding resistance rises to 37.97 Ω at 100 °C, the current under high internal temperature drops to 0.63 A, reducing heat generation while holding torque is maintained. A 100 % duty cycle allows the unit to remain continuously energized without mandatory cool-down intervals. The magnetic circuit exhibits an inductance of 0.7 H, so a controlled dV/dt from the power supply helps limit inrush. After the de-energizing command, the armature lifts within ≤30 ms. The 0.75 mm² conductor cross-section supports this switching profile with minimal voltage drop, and the nominal air gap is set at 0.2 mm for consistent clearance.
When engaged, the brake provides a mechanical holding torque of 15 Nm, provided the nominal air gap is preserved during installation. During energizing, the magnetic field builds fully within ≤120 ms, so the brake releases before motion begins. Environmental sealing corresponds to an enclosure rating of IP40, so the component is protected against solid objects larger than 1 mm but must be mounted inside a closed housing for dust and moisture control. Electronics tolerate a supply variation of ±10 %, allowing the brake to share common 24 V buses that experience ripple.
