Overview of Hysteresis 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.
Structure of Hysteresis Brake
The hysteresis effect in magnetism is applied to torque control
by the use of two basic components-a reticulated pole structure
and a specialty steel rotor/shaft assembly-fastened 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.
