Warner Electric Innovation Marches On
Warner Electric designed and patented the first electromagnetic clutch/brake more than 70 years ago. Since then, Warner has pioneered dozens of significant advances in the design and manufacturing of industrial clutches and brakes. Just within the past year, the company announced two new upgrades to its comprehensive product line of industry-leading clutches and brakes: the Gen2 and the UNIBRAKE©
Gen2 Sets New Standard
The line of Gen2 Packaged Electromagnetic Clutches and Brakes is the latest demonstration of how Warner Electric continues to lead the industry through innovation, service, and reliability.
The Gen2 UniModules provide several improvements over Warner’s long-standing UniModule products.
One upgrade involved the design of a complete new housing for the units. Changes to the housing fin design increases heat dissipation capacities, especially in the enclosed configuration of the UniModule.
Improved input to output axis design reduces vibration and improves noise and wear factors. The addition of custom designed mounting bolts allows the conduit box to be located directly on top of the units which adds convenience and functionality in many applications. Also, bolt hole patterns are re-positioned for ease of mounting.
An add-on enclosure cover kit allows the unit to be completely enclosed as an upgrade in the field without replacing the clutch/brake, thus keeping contaminates out and wear particles in for clean, quiet operation.
The new generation of Gen 2 Packaged Modules are direct replacements of Warner Electric’s range of products in sizes 50, 100 and 180.

UNIBRAKE: Design Simplicity for Enhanced Uptime
UNIBRAKE spring-applied AC 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 newly introduced brakes feature a simple design with fewer moving parts to reduce downtime for stop/hold functions found in material handling, food processing, baggage handling equipment and many other applications.
The operating principle is simple. A 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, thus stopping or decelerating the motion of the load. When an AC voltage is applied, the solenoid creates a direct-acting magnetic force which releases the friction disc without the use of a linkage, allowing the hub and motor shaft to turn freely.
An external manual release lever permits the driven load to be moved without energizing the motor. The lever resets automatically when the brake is reenergized. Two styles are available. The single C-Face mounts on the non-driven end of a motor 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.
Single C-Face UNIBRAKES are available from 3 ft.lb. to 15 ft.lb. Double C-Face UNIBRAKES are available from 3 ft.lb. to 10 ft.lb. Both styles are interchangeable with standard motor brakes.
