Product Specification

Non-Contact Torque Control with Hysteresis Brakes and ClutchesHysteresis brake

Product Overview

Hysteresis brake is a superior torque, tension control component. It uses the principle of hysteresis to produce a certain torque by controlling the input excitation current. There is a good linear relationship between control current and output torque. It provides smooth, stepless and adjustable torque control independent of speed. In addition to the bearing, there is no other friction in the system, which has the advantages of stable and reliable, high speed, low noise, long service life and low maintenance cost.

Structural features

The hysteresis brake is composed of two parts: rotor and stator pole. The rotor is made of special hysteresis material, there is a certain gap in the stator magnetic pole, and the rotor rotates in the gap. When the coil is energized, a magnetic field is generated in the gap, which causes the rotor to produce hysteresis effect. When the hysteresis rotor overcomes the hysteresis force under the action of external forces, the rated torque is generated. The torque is only related to the size of the excitation current, and has nothing to do with the speed, so as to achieve non-contact torque transmission.
