4EB Series 4EB Electromagnetic Single-Face Brakes Stationary Field for Dry Operation Series 4EB electromagnetic stationary field single-face brakes are zero backlash and designed for dry use. When the coil is energized by a DC voltage, a magnetic field is generated which attracts the armature disc to the magnet assembly. The amature disc is connected to a rotating member in the drive by a diaphragm spring. Various brake configurations are available to suit different drive installation requirements. Features • Zero backlash for accurate positioning • Long life asbestos-free friction material • Simple supply connection facilitates installation • 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 other brake duties For Technical Assistance Call Typical Applications • Rapid Start / Stop Machines • Lifting, Slewing and Traveling Motions with Handling Devices • Feed Drives on Machine Tools • Forklift Trucks • Label Printing Machines
