UM Series – Standard & Smooth-Start™ UniModules

Pre-Assembled, Enclosed Clutch/Brake Packages for Industrial Drive Systems

The Warner Electric UM Series UniModule line features completely pre-assembled, one-piece clutch and clutch/brake packages engineered for high-performance installation convenience. Factory pre-aligned and pre-burnished to deliver full rated dynamic torque right out-of-the-box, these enclosed, maintenance-free units easily mount to standard NEMA C-face motors and reducers or operate as separate freestanding drive units via an accessory base. For sensitive mechanical systems requiring soft engagements, the series includes Smooth-Startâ„¢ options utilizing specialized friction materials to minimize mechanical shock and protect delicate machine components.

Key Features

  • Factory Pre-Burnished: Packages are completely assembled and run-in at the factory to achieve full rated torque immediately upon field installation.
  • Patented Autogapâ„¢: Standard configurations feature automatic armature adjustment to compensate for mechanical wear, maintaining exact running gaps and ensuring longevity.
  • Smooth-Startâ„¢ Option: Optional specialized LK friction material configurations provide controlled, less aggressive starts and stops to eliminate harsh mechanical stress.
  • Optimized Heat Dissipation: Constructed with a high-efficiency symmetric housing fin design and standard fan cooling to reliably sustain rapid cycle frequencies.
  • Heavy-Duty Concentricity: Utilizes premium, rigid internal bearing arrangements to preserve tight shaft concentricity, minimizing running noise, vibration, and component wear.
  • Enclosure Versatility: Vented layouts can be easily upgraded in the field using quick conversion cover kits to generate totally enclosed, non-washdown environments without swapping the assembly.

Available Sizes & Ratings

  • Size 50: 16 lb-ft Standard / 10 lb-ft Smooth-Start Static Torque (NEMA 56C / 48Y Frame)
  • Size 100: 30 lb-ft Standard / 18 lb-ft Smooth-Start Static Torque (NEMA 56C / 48Y Frame)
  • Size 180: 30 lb-ft Standard / 18 lb-ft Smooth-Start Static Torque (NEMA 182C / 143TC – 184C / 145TC)
  • Size 210: 95 lb-ft Standard / 57 lb-ft Smooth-Start Static Torque (NEMA 213C / 182TC – 215C / 184TC)
  • Size 215: 95 lb-ft Standard / 57 lb-ft Smooth-Start Static Torque (NEMA 213TC / 215TC)

Ideally suited for packaging machinery, conveyor systems, bottling lines, and delicate material handling setups where reducing mechanical fatigue is critical.

UM Series Selection

  1. Determine Mounting Layout: Establish if the system design dictates a direct NEMA C-face motor/reducer mount layout (1000/1020 series) or an isolated base-mounted separate drive package (2000/2030 series).
  2. Assess Engagement Style: Choose between standard quick-cycling friction faces or Smooth-Startâ„¢ low-shock engagement to protect your payload or downstream mechanisms.
  3. Align NEMA Frame Size: Match the designated motor or reducer size against the Frame Size Selection criteria to secure the proper unit sizing ranging from size 50 up to size 215.
  4. Verify Thermal Loading: For rapid cycle frequencies or high inertia profiles, utilize the standard thermal load formula to verify operation stays within maximum speed-to-heat curve allowances.

How to Order

  1. Define Sizing Suffix: Combine the core primary sizing index with your preferred operational arrangement layout, such as UM-180-1020.
  2. Define System Voltage: Select from standard industrial direct current coil criteria to match your electrical system—available in 6V, 24V, or 90V DC.
  3. Select Mounting Accessories: Supplement base orders with corresponding optional base bracket kits for freestanding shafts, or motor mounts for supported frame configurations.
  4. Incorporate Controls & Enclosures: Specify optional NEMA 4 rated conduit boxes, custom conversion cover plates, or dual-channel torque-adjustable control modules like the CBC-300.
