1 Individual lutch or Brake Module ombine to omprise a lutch, Brake or lutch/brake ombination Electro Modules are individual clutch or brake units which are assembled together to comprise a clutch, brake, or clutch/brake combination. Electro Modules can be bolted directly to a NEM -face motor or reducer or they can be base mounted for stand alone operation. Electro Modules offer the ultimate in clutch/brake convenience. They are easy and quick to install and require no lubrication or maintenance for life. Bolt-it-down and wire-it-up... it s ready to go! Modular design flexibility 1/4 to 7-1/2 HP at 18 RPM Outstanding controllability Fast cycling Smooth starts and stops Original Design Sizes 21 & 215 ccurate Bidirectional GEN 2 Design Sizes 5, 1 & 18 onsistent performance omplete control capability Selection Flexibility lutch/brake ombination wide range of module combinations for use with motors, reducers and other standard power transmission components is available. The flexibility of Electro Module enables you to pick the exact combination of function and design. Power-On pplications Electro Modules for power-on applications are purchased as individual clutches and brakes to be assembled for -face, flange, or base mounting applications. Power-Off (Electrically Released) pplications Electrically released operation is the primary feature of power-off Electro Module brakes. They can be used as brakes, motor brakes and in combination with clutches. See page 16 for complete information. Selection The correct size can be determined from easy-to-use selection charts based on NEM frame sizes or horsepower and shaft speed. Examples show the right way to order the Electro Module required. ontrols Warner Electric controls assure that you get the maximum performance from your Electro Module.

3 Selection Electro Module clutch or brake units may be mounted directly to NEM -face motors and reducers, or can be base mounted. 1. Select onfiguration a. NEM -face Mounting Based on the NEM -face frame size of the prime mover, select the correct clutch or brake module size from the Frame Size Selection chart. Size 1 houses the components of the size 18 in a size 5 frame, while size 215 incorporates size 21 components. b. Base Mounting Electro Module 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 RPM at the module location. The correct size Electro Module is shown at the intersection of the HP and operating speed. For additional sizing information, refer to the technical sizing procedure (step 2). 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. ompare 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.

4 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 urves Heat Dissipation (ft. lbs./min.) Size Maximum Speed 36 RPM 25 F 22 F Speed (RPM) Heat dissipation requirement is calculated as follows: E = 1.7 x WR 2 x (N/1) 2 x F where: E = Heat (lb. ft./min.) WR 2 = Total reflected inertia at the clutch/brake shaft. Include the clutch/brake output inertia. (lb.ft. 2 ) N = Speed in revolutions per minute (RPM) F = ycle rate in cycles per minute (PM) Heat Dissipation (ft. lbs./min.) Size 1/ Maximum Speed 36 RPM Speed (RPM) 25 F 2 F 36 ompare the calculated heat generated in the application to the unit ratings using the heat dissipation curves. Select the appropriate unit that has adequate heat dissipation ability. Heat Dissipation (ft. lbs./min.) Size 21/ Maximum Speed 36 RPM 25 F 2 F Speed (RPM) b. Torque Sizing For most applications, the correct size clutch/brake can be selected from the Horsepower vs. Shaft Speed chart. Determine the motor horsepower and the RPM 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 Specifications Table to select a unit. -face lutch/power-on Brake Dynamic Torque urves For some applications, the torque requirement is determined by the time allowed to accelerate and decelerate the load. (This time is generally specified in milliseconds.) For these applications, it is necessary to determine the torque requirement based on load inertia and the time allowed for engagement. The torque requirements are calculated as follows: T = (WR 2 x N) / (38 x t) where: T = verage Dynamic Torque (lb. ft.) WR 2 = Total reflected inertia at the clutch/brake shaft. Include the clutch/brake output inertia. (lb. ft. 2 ) N = Speed in revolutions per minute (RPM) t = Time allowed for the engagement (sec) Dynamic Torque (lb.ft.)
