Braking Solution for Robot Arms
December 1, 2022
Miki Pulley BXR Brakes are designed for the braking requirements of robot arms used in automated manufacturing systems. They feature enhanced wear resistance and long service life.
Robotic applications in manufacturing need precise movement and positioning in manufacturing operations, from teach pendant programming through full, automated production with exact sequential motion and timed positioning. Miki Pulley BXR Brakes apply holding torque after the motor joint stops and provides dynamic braking in the event of an emergency, such as a power interruption.
The Miki Pulley brake opens and allows for free rotation during robot arm movements and snaps closed when power is disengaged, thus halting position of the arm. When the robot arm is in position for long periods of time, the brake consumes no voltage. The brake's internal compression springs mechanically hold the armature plate against the rotor disc, ensuring no movement. When voltage is re-applied, the brake opens and allows for free movement.
"These Miki Pulley brakes are a cost-effective safety device for all robot holding arms and joints, including cobot systems. They are a positive 'halt and hold' device to mitigate potential mechanical damage to an automated system," said a company spokesperson. "An important operating feature: when compared to most other electric brakes, the unique Miki Pulley brake design is one-half the overall size thickness."
Specifications are:
- Maximum RPM: 6,000
- Static friction torque range: 0.044 ft-lbs. to 2.36 ft-lbs. (0.06 Nm to 3.20 Nm)
- Ambient operating temperature 14 °F to 104 °F (-10 °C to 40 °C).
