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 (Plymouth, MN) 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.
