Description
How does an electromagnetic brake work?
The FAE operates on the principle of electromagnetic attraction. A DC voltage — typically 24VDC — energises the coil inside the inductor body. The resulting magnetic field pulls the brake coil holder, lined with friction material, firmly against the rotating armature disc. The contact between lining and armature generates the braking torque and brings the shaft to a stop.
Once voltage is removed, the spring-membrane built into the armature pushes the friction surfaces apart. This releases the brake and allows the shaft to rotate freely. The cycle — engage on current, release on spring — makes the FAE a positive-action electromagnetic brake, suited for applications where braking must be active and controlled rather than passive.
FAE electromagnetic brake: key technical features
- Current-operated positive braking (energise to brake)
- Spring-membrane release for fast, consistent disengagement
- Three construction variants (1.1, 1.2, 1.3) for different mounting requirements
- Adjustable supply voltage for precise torque adaptation
- Compact design for space-constrained installations
- Compatible with most motor and gearbox manufacturers
- Braking torque range: 1.5 to 700 Nm
- Max. speed: up to 10,000 RPM (size 0.15)
- Operating voltage: 24 VDC (other voltages on request for FAE custom series)
Electromagnetic braking system: construction variants
The FAE is available in three construction variants to cover different mounting and integration requirements.
Construction 1.1 — Basic brake unit. The armature and friction lining are assembled as a single unit and can be mounted directly onto a pulley or sprocket. Ideal when the brake must be integrated into an existing mechanical element.
Construction 1.2 and 1.3 — These variants incorporate the armature and an aluminium bushing for direct shaft mounting. The bushing allows the brake to be installed at the exact point where braking torque is needed, providing a more versatile and adaptable solution.
Electromagnetic brake applications
The FAE electromagnetic brake is used across a wide range of industrial machinery where controlled stopping, holding, or positioning is required:
– Packaging machines: precise stopping at each cycle, synchronised with filling, sealing, or labelling stations
– Product conveyors: controlled deceleration and holding at transfer points – Textile industry: tension control and stopping in winding and unwinding systems
– Machine tools: spindle and axis braking in CNC and machining centres – Industrial filling machines: repeatable stop-and-go cycles in liquid and
powder filling lines
– Cleaning equipment for buildings and facades: motor braking in gondola and platform drive systems
– Servo motor braking: holding torque when the motor is de-energised, preventing back-drive in vertical or inclined axes
For applications requiring a fail-safe brake (spring-applied, released by current), see the FPC safety brake or the FNC pneumatic brake range.
FAE vs OMB: which electromagnetic brake is right for your application?
Both the FAE (EIDE) and the OMB (Precima Magnettechnik) are 24VDC positive electromagnetic brakes sharing the same operating principle. The key difference is availability and customisation. The OMB is EIDE’s standard stocked product for the most common sizes and torque ranges — it ships fast. The FAE is manufactured on request when the application requires a non-standard bore, a specific torque value outside the OMB range, or a custom mechanical configuration that the standard line cannot cover.
If you are unsure which series fits your application, contact our technical team with the shaft diameter, required braking torque, operating speed, and duty cycle.
