UM Series UniModule Pre-assembled, C-face Clutches and Brakes UniModules offer the ultimate in Clutch/ Brake performance and convenience. UniModules offer the same performance as EM’s without the assembly required. Completely pre-assembled onepiece clutch and clutch/brake packages in five sizes. Can be motor or reducer mounted or used as a separate drive unit powered by a prime mover. Pre-assembled, pre-aligned, and pre-burnished at the factory for rated torque directly out-of-the-box. • Easy installation • Available with standard power-on and electrically released power-off brake units • Fan cooled for high cycle rate operation • Maintenance Free Original Design • Available in 50, 100, 180, 210, and 215 sizes. NEMA C-face design • UL listed • Can be applied with control fitted as standard • Bearing mounted clutch rotor eases assembly alignment • Single access hole for all wires

UM Series UniModule UniModule Combinations Clutch Combinations Motor Clutch/Output Clutch Use for clutch only applications. Has hollow bore input for mounting directly to C-face motors. Shaft and C-face on output side of unit accommodates reducer, parallel drive or coupling. Motor Clutch is fan cooled for long life and consistent performance. Basic components are field, rotor and armature. See page 21 in this catalog. Input Clutch/Output Clutch Use for clutch only applications. Features dual C-faces and shafts. Unit input from parallel drive or coupling. Output to reducer. Input Clutch is...

UM Series UniModule Selection UniModule clutch, brake and clutch/brake units may be mounted directly to NEMA C-face motors and reducers, or can be base mounted. 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. 1. Select Configuration a. NEMA C-face Mounting Compare the calculated torque requirement with the average dynamic...

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. Heat dissipation requirement is calculated as follows: F = Cycle rate in cycles per minute (CPM) Compare the calculated heat generated in the application to the unit ratings using...
