Shaft Spring Servo Motor

The core function of electromagnetic power-off brake:
    Safety prevention (power-off braking): At the moment of power outage, the automatic brake is applied by the spring force to prevent vertical load equipment such as cranes and elevators from falling or sliding due to power outage.
     Quick parking: millisecond level response, quickly cutting off the kinetic energy of moving parts, shortening the stopping distance, and improving production rhythm and safety.
     Accurate positioning: Keep the axis position locked in the servo/stepper system to prevent load drift after power failure and ensure repeat positioning accuracy.
     Emergency protection: Force braking in case of emergency stop signal or system failure to avoid secondary accidents caused by mechanical inertia.
Overview of Working Principle:
     Power on state: The excitation coil generates electromagnetic force to overcome the spring pressure, attract the armature, release the friction brake, and allow the shaft to rotate freely.
     Power off state: The electromagnetic force disappears, and the spring immediately applies pressure to push the friction plate to clamp the brake disc, generating friction torque to stop the shaft. ‌‌
Typical application scenarios:
     Vertical lifting equipment (elevators, cranes, hoists);
     Industrial automation (robot joints, servo motors, conveyor belts);
     Special fields (wind power variable pitch system, stage machinery, AGV car).
