4EC Series 4EC Electromagnetic Single-Face Clutches Stationary Field for Dry Operation Series 4EC electromagnetic stationery field single-face clutches are zero backlash and designed for dry use. When the coil is energized by the DC voltage a magnetic field is generated which attracts the armature to the rotor hub, providing the clamping force for torque transmission. The armature is spring-loaded to ensure rapid disengagement and zero drag when disengaged. Various clutch configurations are available to suit different drive installation requirements. Features • Zero backlash • Long life asbestos-free friction material • Stationary field design eliminates brush gear and simplifies supply connection • Zero drag torque when disengaged • Efficient magnet design reduces power consumption and heat generation • Can be used as a continuously slipping variable torque device for torque limiting and tensioning applications • Ideal for high cyclic and all other clutch duties • Sealed for life bearings For Technical Assistance Call Typical Applications • Current Generation Sets-to connect gas/diesel engine-generator • PTO Marine Drives-for compressors and generators • Cutting Machines-to switch the cutter bar • Steel Manufacture and Machining • Paper Production-for transmission connection of the machining centers • Packaging Machines • High Frequency Stop/Start Applications
