BRP Series Electromagnetic Power-off Brakes

BRP Series Electromagnetic Power-off Brakes

Our BRP brakes use economic Hex Drive hubs and can be mounted face up or face down.  Usually less expensive than other lines, these brakes offer Class B (130°C) insulation protection. Spring-set electromagnetic power-off brakes provide a safe, efficient means of stopping and/or holding a load in the absence of power. While the field (electromagnet) assembly is fixed and prevented from rotating, the rotor assembly is secured to the shaft. In the absence of power, the fixed and rotating components are engaged, thus stopping and/or holding the load. When the coil is energized, rotating components are disengaged thus allowing the shaft to freely rotate.
