Magnetic particle brakes are unique in their design from other electro-mechanical brakes because of the wide operating torque range available. Like an electro-mechanical brake, torque to voltage is almost linear; however, in a magnetic particle brake, torque can be controlled very accurately (within the operating RPM range of the unit). This makes these units ideally suited for tension control applications, such as wire winding, foil, film, and tape tension control. Because of their fast response, they can also be used in high cycle applications, such as magnetic card readers, sorting machines and labeling equipment.

Magnetic particles (very similar to iron filings) are located in the powder cavity. When electricity is applied to the coil, the resulting magnetic flux tries to bind the particles together, almost like a magnetic particle slush. As the electric current is increased, the binding of the particles becomes stronger. The brake rotor passes through these bound particles. The output of the housing is rigidly attached to some portion of the machine. As the particles start to bind together, a resistant force is created on the rotor, slowing, and eventually stopping the output shaft.

Electromagnetic brake operation principle:

 

Permanent magnetic brake designed for industrial and mobile applications. Brake force is produced via magnets which reduce both size and weight of brake versus spring applied brakes. Armature is mounted via springs which eliminates backlash. Standard brakes can accommodate temperatures up to 140deg C. Brakes can be tuned to provide a controlled stop. Output assemblies easily modified to fit your application

Magnetic Powder Brake

 

 

 

Sunrise’s magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. When the magnetic coil is not conducting electricity, the torque will not be transmitted from the input shaft to the output shaft, but if the coil is magnetized, the magnetic force will attract the magnetic powder to produce the hardening phenomenon, and the torque will be transmitted between successive slides. Moreover, it has the feature that the excitation current and the transmitted torque are basically linear. It has nothing to do with slip and can transmit a certain torque, and has the advantages of fast response, simple structure, no pollution, low noise, no shock vibration, energy saving, etc. It is a multi-purpose automatic control element with superior performance.

Installation and Use

1. Magnetic powder brake adopts DC as excitation power supply.

2. Magnetic powder brakes do not support the installation method of the radial bearing main power transmission.

3. For the first use of the magnetic powder brake, power off after 10 seconds of operation then power on, repeating several times. ensuring the fluidity and uniform distribution of magnetic particles.

4. The magnetic powder brake cannot be used exceeding normal torque and rotation speed, otherwise the life of the magnetic powder will decrease sharply.
