Woodward Brakes and Clutches

    Woodward’s brakes and clutches are employed in airborne and land vehicle actuation

    Woodward designs and manufactures brakes and clutches for aerospace and defense motion-control applications. These highly-reliable accessory devices are produced in-house and augment Woodward’s motor and actuation products.

    Size & Capacity
    Woodward offers brakes in both round and square frames in popular inch-series diameter codes from Size 8 to Size 50 (.8” to 5.0”), commensurate with many of our standard motor diameters. The available torque capacity extends into the hundreds of inch-pounds using both toothed and plain friction-type disc designs. Woodward designs can be rated for both dynamic- or static-only engagement. Many of these devices are offered with either power-OFF or power-ON to engage, and with manual-release mechanisms, upon request.

    Winding Options & Packaging
    Most brake designs can be wound for 28VDC or less, and up to hundreds of volts. AC-powered designs are also available with or without built-in rectification. Woodward brakes are primarily open-framed, but they can also be simply housed to limit contamination, or completely housed into vehicle-level line-replaceable units (LRUs).

    Hysteresis Torque Devices
    Woodward also designs and manufactures magnetic hysteresis torque devices that are completely mechanical wear-free. We have effectively used these devices for applications such as holding brakes (anti-creep), torque limiters, and magnetic couplings.

    Commonly supplied accessory devices include Woodward’s own gearheads as may be desired to greatly amplify the braking torque produced within the specified volume allowance.

    Woodward is at the forefront of providing reliable and affordable, advanced technology brakes and clutches solutions. For more information or assistance with your particular application, contact us at afs-motors@woodward.com.
