| Electrically Released Brakes |
|
"Electrically Released Brakes" are so named because, when power is removed, the brake engages to stop and/or hold a load. This occurs when power is lost either intentionally or unexpectedly due to a machine malfunction or power outage. When power is returned, the brake electrically releases the load, allowing it to move freely. Warner Electric offers two types of electrically released brakes: spring-set; and permanent magnet. |

Spring-Set Brakes |
Warner Electric's spring-set brakes employ springs to provide the clamping force for load stopping or holding until the brake is electromagnetically released. We offer two spring-set brake product lines: the ERS; and ERD.
ERS Series brakes are designed for providing primarily holding functions, with occasional emergency stops, and are pre-assembled and pre-burnished at the factory.
The ERD Series brakes are a dual engagement brake designed to provide both stopping and holding functions, and are shipped as a kit which requires user assembly. |

Permanent Magnet-Set Brakes |
Warner Electric's permanent magnet brakes use powerful permanent magnets to provide the holding and stopping torque until electric power to the brake coil nullifies the attraction of the permanent magnets, releasing the brake. We offer two product lines employing this design: the FB Series; and the ER Series.
The FB Series offers shaft mounted units in convenient pre-assembled packages, while the ER Series offers a broader range of sizes and is designed for flange mounting. |

Permanent Magnet-Set , Electrically Released Modules |
|
In addition to the FB and ER products, we offer a variety of C-face compatible electrically released brake and clutch/brake modules. Designed for applications requiring frequent cycling, these units also employ powerful permanent magnets to stop and hold loads and are available in a variety of configurations. |
