The recently introduced Miki Pulley BXR-LE brakes were specifically designed for use on robotic arms to reduce the cantilevered load. With accompanying voltage controller, power consumption is stepped down to 7VDC after a split second of 24VDC for brake actuation. When compared to the other BX brakes in the Miki lineup, this BXR-LE design provides just one-third power consumption and heat generation in one-half the overall size thickness. Specifications are: maximum RPM of 6,000; static friction torque range of 0.32 Nm – 1.32 Nm (0.236 ft-lbs - 0.973 ft-lbs); and ambient operating temperature of -20 C - -60 C (-4F - -140 F)
Applications for the BXR-LE brakes include: robotic arm joints to stop movement during a catastrophic power failure; Z-axis ball screw brake on CNC machine centers; mounting on a servo motor face, the slim brake profile saves space.
