Wholesale Air Cooled Compressed Electromagnetic Shaft Clutch High Torque DC 24V Hb Ahb Hc Tension Control Industrial Magnetic Brake
1. These units are developed to ensure that every brake of a given model designation will be matched at a pre-determined torque and current point to every other brake of the same model designation.
2. By possibility of a special adjustment each brake will be matched at the selected match point to within ± 1.5% provided that the match point is above 50 % of the max possible torque.
3. All other points of the curve then are within ± 4% deviation from each other.
4. The use of matched hysteresis brakes is, for example, an advantage for a multi tension control system for multi spool payoff frames.

Hysteresis Brakes Magnetic Clutch Industrial magnetic brake
Standard Hysteresis Brakes produce torque strictly through a magnetic air gap without the use of magnetic particles or friction components. This method of braking provides far superior operating characteristics (smoother torque, longer life, superior repeatability, high degree of controllability, and less maintenance and down time) which make them the preferred choice for precise tension control during the processing of nearly any material, web or strand.
Structural Characteristics
The hysteresis effect in magnetism is applied to torque control by the use of two basic componentsa reticulated pole structure and a specialty steel rotor/shaft assemblyfastened together but not in physical contact. Until the field coil is energized, the drag cup and shaft can spin freely on its bearings. When a magnetizing force from either a field coil or magnet is applied to the pole structure, the air gap becomes a flux field. The rotor is magnetically restrained, providing a braking action between the pole structure and rotor.
Applications
HARTAI Hysteresis Brakes provide precise tensioning for: Armature and coil winding, printing and labeling, wire marking, braiding, material slitting, sheeting, weaving, and many other material process applications. They are ideal for any material, strand or web, including: Copper wire, fiber-optic cable, textiles, tapes, films, foils, paper, rubber products, nylon, and many others.
