Brakes
ABM disk brakes type EFB and ZFB are electro-mechanical safety brakes and stop drives quickly and reliably in any operating mode. There can be no compromises when it comes to safety, and ABM has been developing and manufacturing brakes for 60 years. This experience has resulted in the continuous improvement of brake performance. All brake components and functions are perfectly matched to a particular drive.
The main characteristics and benefits for the user include
• Adjustable torque
• Safe braking in the event of a power loss
• Simple manual adjustment
• Unlimited continuous duty
• Asbestos-free brake lining
• High operating frequency
• Long lining life
• Short On and Off times
Typical Applications
• Cranes, hoists
• Handling and conveying systems
• Machine tools
• Packaging machines
• Textile machinery
• Warehousing systems
Method of Operation
On ABM EFB disk brakes (single-sided brake) the brake coil is cast into the end shield on the brake side. An aluminium impeller acts as brake lining carrier. In de-energized condition a thrust spring supported off the brake end shield presses an axially moving armature base plate against a special brake lining on the impeller.
ABM ZFB disk brakes (2 sided brake) are mounted on the brake side end shield that also acts as one of the brake pads.
Alloy brake disks have a special lining on both faces and lie between end shield and magnet body with armature base plate. In de-energized condition a number of springs press the armature base plate against the brake disk and bring it into contact with the end shield.

Supply Voltages
The standard supply is 230 V AC, 50 Hz when connected to the rectifier. Other supply voltages upon request. The brake's OFF time can be adapted to individual applications by AC side or DC side switching, i.e. making precise rapid braking or delayed soft braking possible. The operating time can be reduced with a high-speed excitation rectifier.
