Brakes Offer More Stopping Power

​Today's machine designs depend on servo motors for fast, powerful and controllable motion. Holding accurate position is often critical.  That’s where Miki Pulley’s Electro-Magnetic Brakes provide the ideal solution.

These Miki Pulley spring-applied Electro-Magnetic Brakes safely hold a static position, without the need for external power. The BXR-LE Miki Pulley brake series is a power-off, engaged brake design.  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 rotation during power failure events.

Now there are 6 total size configurations in the BXR-LE series to choose from, all of which are designed for smaller machine and robotic applications, where cantilevered loads can negatively impact operation. 

Of particular importance -- these brakes have a slim design and high holding torque in a very compact package.They provide quiet operation with long service life. 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.

Compared to the other brakes in the broad Miki lineup, the revolutionary BXR-LE design provides just one-third power consumption and heat generation in one-half the overall size thickness of comparable brakes on the market. 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)
