Robotic arms continue to prove their critical value in the manufacturing industry by expanding versatility in automation.  Within all facets of the industry, positive control and safety are key.  In the event of a catastrophic power failure, robotic arm movement must be captured and stopped to prevent mechanical collapse and equipment damage.

For OEMs, this requires choosing brakes made with robotics applications in mind. The design must offer stable, reliable holding and stopping. Brakes intended for robotic arms should also be lightweight to minimize cantilevered loads and meet your technical requirements for backlash and torque.

Highly Responsive, Fail-Safe Robotic Arm Braking

Miki Pulley’s spring-actuated robotic arm brakes work as both a holding brake and a “power off” emergency brake. When power is disengaged, compression springs immediately constrain the rotor, providing for a highly responsive braking force which includes rapid halting and long-term holding.  This dynamic response prevents dangerous uncontrolled movement.

Low Backlash Performance and Precise Positioning

With minimal backlash at starts and stops, our spring-actuated brakes for robotics maintain precise positioning across all functions. The unique energy-saving power control module on the BXR-'LE reduces coil temperature during operation. BXR brake units can be installed on servo motors without inhibiting responsiveness.

Small and Streamlined Robotic Arm Brake Designs

Miki Pulley BXR Model robotic arm joint brakes deliver high holding and stopping torque in a compact package. A compact, lightweight design means you can add multiple robotic arm joint brakes without weighing equipment down or inhibiting arm movement and performance.
 

BXR Model Robotic Arm Brakes

BXR Model robotic arm brakes feature low-inertia rotors that dramatically reduce both mass and drag wear while providing more than adequate strength. These robotic arm brakes have a lightweight design that significantly reduces idling wear and offer 5 Nm to 55 Nm of braking torque. The thin profile is roughly 2/3 the thickness of other industry-standard brakes, streamlining the articulating joint housing design.
