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.
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: 6000
• Static friction torque range: 0.044 to 2.36 ft.lb. (0.06 to 3.20 Nm)
• Ambient operating temperature 14 – 104°F (-10 to 40°C)
