Miki Pulley spring-applied electromagnetic 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. 

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.

Typical servo motor applications include: Robotic arm joints to stop movement during a catastrophic power failure, Z-axis ball screw brakes on 3D printers, Pan/tilt brakes for security cameras, brakes for locking sensor alignment and many more.
