    Magnetic powder brake structure and principle of operation

    The magnetic powder brake structure is shown in Fig. 1. The drive member linked to the input side and the driven member fixed on the stator are disposed concentrically across a powder gap.

    The powder gap is filled with powder (magnetic iron powder), and the coil for passing a magnetic flux to the powder is built in the stator, and it is designed to feed direct current from outside through the lead wire.

    While the drive member is rotating, when a current flows in the coil, a magnetic flux is generated as indicated by broken line in the drawing, and the powder is linked like a chain along the magnetic flux, so that the drive member and driven member are coupled together. Since the driven member is fixed on the stator, it works as a brake.

    When the exciting current is cut off, the magnetic flux disappears, and the coupling force of the powder is eliminated, thereby cutting of transmission of powder to the driven member.

    Magnetic Powder Brake Mounting

    (1) Fasten the fitting part of the bracket to the mounting plate and fix it.

    (2) Be careful of the length of the mounting bolt. If the mounting bolt is too long, the tip of

    the bolt may interfere with the rotating part.

    (3) Set the concentricity between the brake side threading shaft and the load shaft to 0.05mm or less.

    (4) Since the outer periphery rotates, be sure to cover the e whole body with a wire mesh or the like with good ventilation.

    Caution before assembling of magnetic powder brake

    1) Turn off the powder and make sure rotating elements are stopped.

    2)Tighten bolts to specified torque and lock securely

    3)Connect lead wire securely

    4) Be sure to connect a surge absorber parallel to the exciting coil to cut off the direct current.

    5) Use wire size suited to current capacity

    6)Mount, dismount and transport with treatest care

    Note: The hoist operation by using the eyebolts should be done by a qualified operator.

    Assembling of magnetic powder brake

    (1) In assembling work, don't attempt to put in by force.

    When inserting the output shaft to the machine, in particular, hold the shaft of the driven member.

    (2) Use the magnetic powder clutch in the regular installation status in which the high-speed rotation side is located as the input side. (The nameplate indicates the input side and output side with arrows.) Install both the magnetic powder clutch and magnetic powder brake so that the shafts become horizontal.

    (3) For coupling with the load shaft, use an elastic coupling.

    (4) For pulley coupling, pay attention to the belt tension, and never apply initial tension more than necessary.

    (5) Use screw 1 of the fin side of the magnetic powder clutch, and lock the stator without applying excessive force. Complete fixing may break the bearing or other parts. The effective dimension of this screw is shown in Fig. 1, but if longer than necessary, it must be noted that it may interfere with part B of the bracket.

    (6) The voltage polarity is not specified.
