Operating Principles 

DYF series brakes are spring applied brakes and do the braking when energy is not applied.
When energy applies to the brake coil (1), a magnetic field creates.
This magnetic field overcomes the force of the pressure springs (2) and ensures that the pressure flange (3) compresses the springs and pull them towards the coil.
As a result, the brake pad (4), which has friction surfaces on both sides, releases. When the energy is cut off, the magnetic field disappears, the compressed springs releases and they ensures the pressure flange to be push towards the brake pad and braking.

Assembly Applications

Uncooled Type Brake Assembly



It is one of the standard assembly types of DYF spring applied brake series. It uses in systems where the switching is not frequently.

Cooled Type Brake Assembly



It is one of the standard assembly types of DYF spring applied brake series. It uses in systems where the switching is frequently and operating under intense working conditions.

Brake Assembly with Forced Axial Fan



Forced axial fan brake uses in driver-operated systems in cases where the brake switching is frequently or where the ambient temperature is high.

Brake Assembly with Hand Release



It uses in case of de-energized the system or when the brake needs to be released manually. It uses in places such as outdoor elevators, conveyor belt systems, crane systems.

Brake Assembly with Encoder + Double Brake



It uses in systems (elevators, stage systems) that require high level of security as required by standards.

Brake Assembly with Encoder + Forced Axial Fan + Hand Release



It uses in cases where the working conditions are intense, the ambient temperature is high and the system needs to be controlled. It uses in places such as automation systems, crane systems.
Optional Parts

Hand Release


The hand release uses to release the brake manually. After release, the hand release returns automatically to its main position. This hand can be assemble on brake subsequently

Mounting Flange


The mounting flange is the flange that uses when there is no suitable friction surface on the existing motor cover or counter surface.

Double brake mounting flange


It is a special flange designed to connect the second brake when double brake application is required and safety requirements are high.

Encoder Flange


It is a special flange designed for asemmbly the encoder to the brake according to the appropriate brand and model of the encoder in cases where it is necessary to assembly the encoder

Stainless Steel Friction Plate


It uses to obtain a friction surface in order to increase the operating performance of the brake in cases where ambient conditions are special (humidity, temperature, corrosion etc.).

Dust Seal


It prevents external factors such as moisture, liquid and dust particles from entering the braking area. The Dust seal is placed between the groove on the brake and the mounting groove on the counter friction surface (brake cover or mounting flange).

Proxymity Switch


Proxymity switch provides monitoring of brake switching function and pad wear. It provides remote monitoring the brake and gives information about its operating state. By following the wear distance of the brake pad (0.8 mm), in case of negative situations caused out of tolerance working gap distance, the situation detectes with the help of the sensor and the general system keeps under control.

Micro Switch


Micro switch provides monitoring the switching function of the brake. Monitoring the brake remotely, the operating performance of the brake can be observe and obtain informations in case of negative situation.

Motor Connection Cover


At brake assemblies uses special brake connection cover for motors. These covers are manufactured according to motor brands, from 63 type to 250 type (ELK, GAMAK, Volt, WAT, Siemens, Omega, AEMOT).

Forced Axial Fan


Forced axial fan brake uses in driver-operated systems in cases where the brake switching is frequently or where the ambient temperature is high. Forced axial fans cools the motor and brake, this provides the operation efficiently and long life of the system.
