Expanded Size Selection For BX Series Brakes From Miki Pulley

May 3, 2017 By Janae Garrett Leave a Comment

Electromagnetic Miki Pulley BX series brakes are a power-off, engaged type brake.  When the stator is energized, the brake is disengaged allowing free rotation.  When no current is applied, compression springs halt the brake rotor thereby stopping the input shaft rotation.  This is an ideal feature to prevent power failure events.

Of the BX series, the BXR-LE has expanded to 3 additional sizes.  (6 total size configurations to choose from.)  These brakes boast advantages including a slim design and high holding torque in a compact package. They provide quiet operation with long service life.  This brake was designed for smaller machine and robotic applications, where cantilevered loads can negatively impact operation. The brake’s unique compact and lightweight design optimizes machine design efficiency. 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 revolutionary BXR-LE design provides just one-third power consumption and heat generation in one-half the overall size thickness. Specifications are:

  • Maximum RPM: 6000
  • Static friction torque range: 0.06 Nm – 3.20 Nm (0.044 ft-lbs – 2.36 ft-lbs)
  • Ambient operating temperature: -20 C — 60 C (-4 F — 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
  • Internal brake for direct drive servo motors
  • Pan/tilt brake for security cameras
  • Brake for locking sensor alignment
  • Z-axis brake
