High-Performance Durable YHSA Hysteresis Clutch for Wire Machinery

Hysteresis clutches are a particular variant of electromagnetic couplers used when a constant torque from zero to the synchronous speed needs to be transmitted. Sunrise Group provides the hysteresis clutch with allowable rotating speed to 3000 r/min, rated current 1.0A.

    Hysteresis Clutch Structure And Principle Of Operation

    ● Figures 1 show typical structures of hysteresis clutch.

    ● The hysteresis clutch is composed of three parts: stator, first rotor and second rotor.

    ● The stator has an exciting coil contained inside, and the first rotor comprises inner and outer magnetic poles. Between these magnetic poles, a cupshaped permanent magnet (not magnetized) of the second rotor is interposed.

    ● Suppose the first rotor is rotated to excite the exciting coil, a rotating magnetic field is generated in a gap formed by the inner and outer magnetic poles of the first rotor, and the permanent magnet of the second rotor placed in the gap is magnetized, but since the permanent magnet has a hysteresis characteristic, the change of polarity of the permanent magnet is later than that of the magnetic poles, thereby coupling the first rotor and second rotor magnetically, so that torque can be transmitted.

    Hysteresis Clutch Feature

    01
    FAST RESPONSE
    The torque of YHSA series electromagnetic hysteresis clutch is independent of slip speed. Torque is directly proportionate to coil current, thus the torque of each unit can be adjusted by varying the current. Once the current is stable, the torque remains constant.
    22 (3)
    02
    REPEATABILITY
    The YHSA series hysteresis clutches will always duplicate performance under identical operating conditions.
    22 (2)
    03
    SMOOTH OPERATION
    The YHSA series hysteresis clutch does not utilize mechanical friction; therefore, operation is smooth at any slip speed.
    22
    04
    LONG LIFE
    The YHSA series hysteresis clutch produces drag torque without physical contact (friction) of parts and are not subject to wear (except the normal wear of antifriction bearings).

    EASY MOUNTING
    Mounting is effortless - no adjustments to make, no gaps to set. The YHSA series hysteresis clutches may be mounted in the horizontal or vertical position.

    Hysteresis Clutch Torque Adjustment

    ● The relation of torque and exciting current is almost proportional as shownabove, and therefore by adjusting the current, the torque can be easily adjusted.

    ● Set to a proper value in consideration of the finish of the product or working condition.

    Hysteresis Clutch Maintenance

    Turn off the power, and make sure rotating elements are stopped.

    ● Unlike the other type of clutch and brake, hysteresis clutch and hysteresis brake are noncontact type. Therefore, it requires no adjustment which is otherwise required to compensate time-change. but please avoid to use the unit in the high temperature or high humidity or in the atmosphere full of dust.

    ● Check the coupling mounting bolts and others for looseness.

    CAUTION For Hysteresis Clutch
