EM Series Electro Module Individual Clutch or Brake Module Combine to Comprise a Clutch, Brake or Clutch/Brake Combination 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 NEMA C-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 1800 RPM • Outstanding controllability • Fast cycling Original Design • Smooth starts and stops • Consistent performance • Complete control capability Selection Flexibility Clutch/Brake Combination A 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 Applications Electro Modules for power-on applications are purchased as individual clutches and brakes to be assembled for C-face, flange, or base mounting applications. Power-Off (Electrically Released) Applications 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 106 for complete information. Controls Warner Electric controls assure that you get the maximum performance from your Electro Module. See page 201. Selection The correct size can be determined from easy-to-use selection charts based on NEMA frame sizes or horsepower and shaft speed. Examples show the right way to order the Electro Module required.

EM Series Electro Module Modular Components Clutch Modules 10 Motor Clutch Fan cooled for long life and consistent performance. See page 30. 30 Input Clutch Fan cooled. Sealed coil. Twin bearing mounted shaft maintains tight concentricities. See page 33. 40 Output Clutch Autogap™ automatically adjust armature for wear. Does not have a coil – use in combination with a 10 Motor Clutch or 30 Input Clutch module. See page 34. Clutch Combinations 10/40 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...

EM Series Electro Module Selection Electro Module clutch or brake units may be mounted directly to NEMA C-face motors and reducers, or can be base mounted. 2. Determine Technical Requirements 1. Select Configuration a. NEMA C-face 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...

EM Series Electro Module 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. E = 1.7 x WR2 x (N/100)2 x F where: E = Heat (lb. ft./min.) WR2 = Total reflected inertia at the clutch/brake shaft. Include the clutch/brake output...
