Nursan Electromagnetic Brakes

A robust and rigid construction has been incorporated into the assembly and design of the NYBF series brakes. The noise level is below 70 dB. High braking torque is provided for motors of various types and frame sizes. The ventilated (cooled) brake design facilitates effective dissipation of the heat generated during braking, thereby minimizing the temperature rise of the brake lining/pad. The electromagnetic winding is wound on a coil former manufactured from heat-resistant material and protected with polyester (coil insulation class: H). All mechanical parts are electrolytically coated to provide corrosion protection. The brake lining discs are manufactured from 1050-grade carbon steel across all models. Long-life, high-friction, asbestos-free linings are used. The brake coil housings are produced from GGG42 ductile cast iron to minimize hysteresis losses. The brakes are designed to be compatible with various motor types by changing the intermediate coupling flange.

NABF Series Current-Applied Brakes are generally used in applications that require very frequent start-stop cycles and need to stop with precision.
When power (24 VDC) is applied to the brake coil, the magnetic field created on the surface of the brake coil casing (No:2) pulls the friction flange (No:4) towards it, performing the braking action, and this continues as long as power is applied. When the power is cut, the friction flange (No:4) separates from the coil casing surface by means of the spring (No:5) located underneath, and the braking is terminated. NABF Series Current-Applied Brakes are systems with very frequent switching (Example: They have the capacity to perform 40 to 100 on-off cycles per minute).
They have the opposite operating principle of the spring-applied NYBF and NYBF (MK) Series brakes.
NABF Series Brakes are produced as 24 VDC.
