The UNIBRAKE® AC Motor Brakes from Warner Electric

As Warner Electric continuously strives to better serve our customers’ needs, we are pleased to announce the latest addition to the Warner Electric product offering - UNIBRAKE® AC Motor Brakes.

Warner Electric spring applied motor brakes are designed to decelerate or park inertial loads when the voltage is turned off, either intentionally or accidentally, as in the case of power failure. The friction disc with the hub is coupled to the motor shaft to be braked but is capable of moving axially. When power is off, a spring force clamps the friction disc between a pressure plate and a stationary plate, hence retarding motion. When an AC voltage is applied, the solenoid creates a Direct Acting magnetic force which releases the friction disk without the use of a linkage. This allows the hub and motor shaft to turn freely.

Simple design with fewer moving parts means less downtime.

Two mounting styles are available: the single C-Face brake and the double C-Face brake. The single C-Face mounts on the non-driven end of a motor. The C-Face brake is interchangeable with existing brakes and can be used on motors that are modified to accept a brake. The double C-Face brake can be used as a coupler between standard C-Face motors and C-Face gear reducers. All motor brakes are interchangeable with competitive motor brakes.

UNIBRAKE® is available to meet the demands of a wide variety of applications 

The motor brakes are commonly used as parking brakes to hold a load in place or as stopping brakes to dynamically decelerate a load. Applications include:

  • Material Handling
  • Food Processing
  • Machine Tools
