About WARNER ELECTRIC

Warner Electric is a manufacturer of motion control products, with a history dating back to the mid-20th century. The brand is part of the Altra Industrial Motion group, a global supplier of electromechanical power transmission components. Warner Electric's product portfolio includes clutches, brakes, tensioners, and controls used in industrial applications to start, stop, hold, or tension loads. The company's products are commonly found in material handling, packaging, converting, and other automated machinery where precise motion control is required.

3G Electric supplies Warner Electric clutches and brakes, with a focus on C-face brakes for NEMA motors and reducers. The current selection includes spring-set holding brakes and magnetic clutch/brakes in vented enclosures. These units operate at 24V DC or 90V DC and provide static torque ratings from 16 ft-lb to 95 ft-lb. Many models include mounting hardware and are designed for direct mounting on NEMA C-face motors or between a motor and reducer. Shaft diameters of 5/8 in and 7/8 in are available in the disc brake variants. The spring-set holding brake, such as the ERS-68 for 215TC motor frames, is used to hold a motor shaft stationary when power is removed, a common requirement in conveyor and industrial machinery applications.

Warner Electric brakes are engineered for stopping and holding duties. The vented enclosure design aids heat dissipation during cycling, which can extend service life in repetitive operations. The C-face mounting configuration simplifies installation and alignment with standard NEMA motors and reducers. 3G Electric supports this line by stocking multiple SKUs and providing logistics support for global delivery. Technical buyers can compare specifications such as voltage, torque, and shaft diameter to select the appropriate model for their application. For assistance with selection or integration, 3G Electric's team can provide product data and availability information.

Common Applications

  • Conveyor systems — Warner Electric C-face brakes (e.g., 2DBN8) for controlled stopping and holding of conveyor belts.
  • Packaging machinery — Spring-set holding brake (305P81) for fail-safe holding of motor shafts during power loss.
  • Material handling — Magnetic clutch/brake (2DBN4) for start-stop cycling on NEMA C-face motors.
  • Industrial automation — Vented C-face brake (2DBN1) for heat dissipation in repetitive stopping applications.
  • Converting equipment — Warner Electric disc brake (2DBN2) with 5/8 in shaft for tension control.
  • Lifting mechanisms — Spring-set brake (305P81) for holding loads stationary when power is removed.

Frequently asked questions

Common questions about WARNER ELECTRIC from 3G Electric.

What is the difference between a Warner Electric C-face brake and a spring-set holding brake?

Warner Electric C-face brakes are magnetic clutch/brake units that mount directly to NEMA C-face motors or reducers. They engage when power is applied and are used for stopping or holding. Spring-set holding brakes, such as the ERS series, use springs to engage the brake when power is removed, providing fail-safe holding. The ERS-68 model is designed for 215TC motor frames and operates at 24V DC. Both types are available from 3G Electric with mounting hardware and terminal kits where applicable.

What voltage options are available for Warner Electric brakes?

The Warner Electric brakes supplied by 3G Electric are available in 24V DC and 90V DC configurations. For example, the 2DBN8 model operates at 24V DC with 95 ft-lb static torque, while the 2DBN1 model operates at 90V DC with 16 ft-lb static torque. Voltage selection depends on the available power supply and the required torque for the application. Both voltage options are common in industrial control systems.

How do I select the correct Warner Electric brake for my NEMA C-face motor?

Selection depends on motor frame size, required static torque, voltage, and shaft diameter. Warner Electric C-face brakes are designed to mount directly on NEMA C-face motors or between the motor and reducer. Check the motor frame designation (e.g., 215TC for the ERS-68) and the shaft diameter (5/8 in or 7/8 in for disc brakes). Torque ratings range from 16 ft-lb to 95 ft-lb. 3G Electric provides detailed specifications for each SKU to assist with matching the brake to your motor and application.

What is the purpose of a vented enclosure on Warner Electric brakes?

The vented enclosure on Warner Electric brakes allows heat generated during braking cycles to dissipate more effectively. This is particularly important in applications with frequent stopping or holding, where heat buildup can affect performance and service life. The vented design is standard on many C-face brake models, including the 2DBN series. It does not compromise the brake's mechanical integrity but requires consideration of the operating environment to prevent ingress of contaminants.

Are mounting hardware and terminal kits included with Warner Electric brakes from 3G Electric?

Yes, many Warner Electric brakes supplied by 3G Electric include mounting hardware. For example, the 2DBN8, 2DBN4, 2DBN1, 2DBN6, 2DBN7, 2DBN2, and 2DBN5 models include mounting hardware. The spring-set holding brake 305P81 includes a terminal accessory kit. These inclusions simplify installation and ensure that necessary components are available. Always verify the specific SKU's included items before ordering.

What applications are typical for Warner Electric C-face brakes?

Warner Electric C-face brakes are used in industrial automation, conveyors, packaging machinery, and other equipment requiring controlled stopping or holding of motor-driven loads. The spring-set holding brake is often used where a load must be held stationary when power is removed, such as on inclined conveyors or lifting mechanisms. The magnetic clutch/brake models are suitable for start-stop cycling and tension control. 3G Electric supplies these brakes for global delivery to support maintenance and new installations.
