Brakes used on servo motors are very critical because they not only are expected to perform the function of stopping and holding the rotor, but also could be a safety concern if they fail to operate properly. Brakes should be replaced if the are worn out considerably at the time of repair. Axxa has the capability to customize variants of spring-applied and electromagnetic brakes for servo motors. Additionally, we also stock brakes for leading servo motor manufacturers.
- Spring-Type Brake- Used without electricity springs against a pressure plate, squeezing both the inner and outer plate. The clamping force is transferred to the hub which is connected to the shaft.
- Electromagnetic Brake- stops and holds a load when electrical power is disconnected. Additional disks can be used to increase torque without changing the size of the brake.
- Permanent Magnet Brake- works by using a permanent magnet to attract a single face armature. After the brake is engaged the permanent magnet creates lines of flux, which attracts the armature to the brake housing.
