PRODUCT DESCRIPTION
The Warner Electric EP Series Electro Pack is a pre-assembled, factory-aligned clutch and brake combination package contained in a rugged, fully enclosed housing. Designed for direct foot-mounting, these pre-burnished packages eliminate the need for complex field engineering, shaft alignment, and individual component assembly. The enclosed industrial design protects internal components from dirt, dust, and moisture while sealing in wear particles, making the EP Series an ideal solution for convenient, long-life, high-cycle industrial motion control.
FEATURES
- Pre-Engineered and Pre-Assembled Package: Incorporates more than twenty distinct precision elements into a single, compact housing to simplify machinery footprints.
- Factory-Aligned Bearings and Shafts: Input and output shafts are perfectly positioned and supported during manufacturing to prevent premature bearing or alignment wear.
- Totally Enclosed Housing: The rugged protective outer shell seals out ambient moisture, oil mist, and debris while containing friction wear particles inside.
- Ceramic Friction Option Matrix: Available with specialized ceramic-on-ceramic contact interfaces to extend package life up to 3 to 5 times over conventional assemblies in heavy-duty cycles.
- Single-Point Conduit Electrical Exit: Streamlines industrial wiring configurations by routing all internal coil leads through a single, secure exit node.
SELECTION PROCEDURE
- Step 1: Determine the clutch or brake function—Wrap spring clutches and brakes can perform three control functions overrunning, start-stop and single revolution. Determine the function that will provide the best control for your application.
- Step 2: Determine the size—To select the correct size unit, determine the maximum RPM at which the clutch or brake will operate and the shaft diameter on which the wrap spring unit will be mounted. Locate the appropriate speed and shaft diameter points on the selection charts.
- Step 3: Verify the design function considerations—Once the appropriate series and model size have been determined, review the design considerations and the checklist of options detailed in the “How to Order” section for each series.
HOW TO ORDER
- Reference Manufacturer Designation: Specify part identifier 5130-273-054 to source the standard 90V DC ceramic-faced model EP-250-C setup directly.
- Verify Voltage Matching: Match field control line parameters against the required 90V DC coil configuration to protect internal winding limits.
- Select Power Supply Accessories: Pair with Warner Electric WSCC series overexcitation control units to manage high-cycle current switching speeds safely.
