The hysteresis brake consists of two main parts: the rotor and stator magnetic poles. The rotor is made of special hysteresis materials, and there is a certain gap in the stator magnetic poles, in which the rotor rotates. When the coil is energized, a magnetic field is generated in the gap, causing a hysteresis effect on the rotor. When the hysteresis rotor overcomes the hysteresis force and rotates under external force, it produces the rated torque. The torque is only related to the magnitude of the excitation current and is independent of the rotational speed, achieving non-contact torque transmission.
What is a hysteresis brake
Hysteresis brake is a high-end torque output control component, with superior design providing various advantageous electromagnetic and friction free devices for these hysteresis devices. It is a friction free operation mode, with smooth torque, infinitely adjustable, and almost no wear. The advantages of these designs are maintenance free, long service life, low average operating cost, wide speed range, excellent environmental stability, and smooth operation.
Hysteresis brakes are applied as torque loads and power absorption in life tests such as testing platforms and drivers. Applied as tension control in unwinding and unwinding equipment for wires, cables, ropes, wires, paper, and tapes. Used as a coupling and overload protection during the startup loading process. Quiet, frictionless, maintenance free, and long service life at work. Torque is largely independent of speed. The torque is infinitely adjustable.
