Selection UniModule clutch, brake and clutch/brake units may be mounted directly to NEMA C-face motors and reducers, or can be base mounted. 1. Select Configuration a. NEMA C-face Mounting To select the correct UniModule package, determine the NEMA frame size of your motor and/or reducer, and choose the corresponding size UniModule from the Frame Size Selection chart. Size UM-1 modules utilize a 5/8" diameter shaft to fit 56C/48Y motor frames with components of UM-18 units for higher torque and heat dissipation capacity than the UM-5. UM-1 modules are available in 12 and 23 clutch/brake and 14 and 34 clutch configurations. For C-face mounting, select either a 12 clutch/brake or a 14 clutch configuration. The 23 and 34 configurations are for base mounting. Frame Size Selection NEMA Frame Size UniModule Size 56C/48Y UM-5* UM-1** 182C/143TC 184C/145TC UM-18 213C/182TC 215C/184TC UM-21 213TC/215TC UM-215 * For 56C/48Y Frame motors 3/4 H and smaller the UM-1 size may be used where extended life is desirable. ** UM-1 size is recommended for motors 1 H and larger. b. Base Mounting UniModule assemblies may be mounted as separate drive units driven from the prime mover by V-belts, chain and sprockets, couplings, timing belts and other standard power transmission components. Select the correct size module from the Horsepower vs. Shaft Speed chart by determining the motor horsepower and RM at the module location. The correct size UniModule is shown at the intersection of the H and operating speed. For additional sizing information, refer to the technical sizing procedure (step 2).

Determine Technical Requirements Technical considerations for sizing and selection are torque and heat dissipation. Each merits careful consideration, especially heat dissipation as over time, use in excessive temperature environments will have an adverse effect on bearing life and coil wire insulation integrity. Compare the calculated torque requirement with the average dynamic torque ratings. Select a unit with adequate torque. If the unit selected on torque is different than the unit selected based on heat, select the larger size unit. 16 Warner Electric 8-825-6544-1234-WE 12/17
a. Heat Dissipation Sizing Friction surfaces slip during the initial period of engagement and, as a result, heat is generated. The clutch/brake selected must have a heat dissipation rating greater than the heat generated by the application. Therefore, in high inertia or high cycle rate applications, it is necessary to check the heat dissipation carefully. Inertia, speed and cycle rate are the required parameters.

Size 5 12 1 8 6 4 2 Maximum Speed 36 RM 25 F 22 F 9 18 27 36 Speed (RM) Heat dissipation requirement is calculated as follows: E = 1.7 x WR2 x (N/1)2 x F where: E = Heat (lb. ft./min.)

Torque Sizing For most applications, the correct size clutch/brake can be selected from the Horsepower vs. Shaft Speed chart on page 16. Determine the motor horsepower and the RM at the clutch/brake. The correct size unit is shown at the intersection of horsepower and shaft speed. If the static torque requirements are known, refer to the technical ratings chart to select a unit.
