Efficient power-saving braking for mobile robots is critical to minimize battery charging downtime. The new larger size Miki Pulley (Plymouth, MN) BXR-LE brakes are ideal for factories and similar applications using mobile robots.
These new BXR-LE brakes provide exact sequential motion and timed positioning. They apply holding torque after the motor joint stops and provide dynamic braking in the event of an emergency, such as a power interruption. Additionally:
- The Miki Pulley brake opens and allows for free rotation during robot movements and snaps closed when power is disengaged, thus halting position of the robot.
- When the robot 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.
- The new power control module on these new brake sizes continuously steps voltage down from 24V to 12V to mitigate power usage and heat buildup.
These Miki Pulley brakes are a cost-effective safety device for all types of mobile robots including cobot systems. They are a positive “halt and hold” device to mitigate potential mechanical damage to an automated system.
