Current Controlled Hysteresis Brakes applied to torque control , Magnetic Brake
Product Description
Features of the Current Controlled Hysteresis Brakes :
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 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.
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.
HARTAI Hysteresis Brakes provide precise control of wire tension during wind, hook and cut operations of high speed automated winding machines. |
Transformer and coil winding operations employing Hysteresis Brakes in open loop control for maintaining precise tension during winding process. |
Precision gap control using Hysteresis Brake and photo sensor. |
Unwind tension control by means of follower arm with potentiometer, Hysteresis Brake and controller. |
HARTAI Hysteresis Brakes offer frictionless, non-breakaway force for tensioning materials during slitting and many other material processing operations. |
The indefinite repeatability, controllability and longevity of ZL's Hysteresis devices has earned them recognition in high end, state-of-the-art exercise equipment applications where precise load control and programmed repeatability are essential. The HARTAI Hysteresis Brake is used in precision computerized diagnostic equipment, as well as in regular exercise machines. |
HARTAI Hysteresis Brakes are widely used in load simulation applications for life testing on electric motors, actuators, small gas engines, gearboxes, and many other rotating devices and assemblies. The ability of hysteresis devices to withstand high temperatures for prolonged periods of operation without suffering any degradation to their magnetic structures makes them ideal for these applications, as well as environmental testing, and even applications in outer space. |
Their ability to produce torque independent of speed makes Hysteresis Brakes the preferred method of braking employed in many dynamometers used for performance testing of motors, actuators, gas engines, etc. |
Their ability to produce torque independent of speed also makes Hysteresis Brakes valuable in applying pre-loads for preventing backlash, backdriving loads, and in limiting torque to prevent damage to delicate assemblies. HARTAI Hysteresis Brake used for holding of backdriving load. |
