Hysteresis Brake

Product name:HB series standard hysteresis brake

HB series standard Hysteresis brakes are categorized into single ended shaft and double ended shafts, and are being widely sed for torque loading and power absorption in test benches, actuators, etc.

Working principle
  The stator poles in a mesh shape and a rotor /shaft assembly made of special materials are fixed together but do not touch each other, and the hysteresis principle in magnetism can be used to control the torque. When the pole coil is not energized, the rotor / shaft can rotate freely on the ball bearing. But when the coil a magnetic force generated by a magnet or a role in the stator flux during the poles, the air gap into the magnetic field i.e., the rotor also because of the hysteresis effect and produce a braking effect. Since the torsion force is completely generated by the magnetic field between the air gaps, rather than the effect of friction or shear, the hysteresis brake can provide an absolutely smooth, continuously adjustable torsion load, which is not affected by the speed and operates quietly and silently. Except for ball bearings, there are no components that wear out.
 
 
 

  In current-controlled hysteresis brakes, torque adjustment and control is provided by the excitation coil. This allows full control of the torque by adjusting the DC current of the excitation coil. Adjustable from a minimum value (bearing resistance) to a maximum value of 10-20% above the rated torque. These brakes use the same working principle as our permanent magnet hysteresis brakes, but the magnetic field is replaced with a magnetic field coil, which provides the precise magnetic field strength required for the rated torque. Hysteresis brakes can be divided into three types according to the cooling method, natural air cooling type, compressed air cooling and blower cooling.
