DC Brake motor


The motor is integrated with DC brake working in low noise and is applicable to a variety of power sources. The exceptional structure design brings excellent braking force with a good flexibility, which is suitable to work under environment that requires for frequently emergency stops and running-stops. It can also be used to prevent mechanical reversal and ensure to stop a heavy load of the burden with large inertia in a short period of time.

  • Low-Voltage Squirrel-Cage Induction Motor (SCIM)
  • Designed and certified withnewest CQC standard.
  • All sizes are conformed to IEC International general standard
  • Quality is certified by CQC and JEM standards.


  • Emergency and Inching Stop: Banding Machine, Crane, Conveyer, Primary Power Axial on Machine Tools.
  • Highly Frequent Start-Stop: Primary Power Axial on Machine Tools, Operation on Automated Control Unit.
  • Stop a heavy load with large inertia in a short period of time: Centrifuge, Twisting Machine, Textile Machine.
  • Danger Prevention: Woodworking Machine, Textile Machine, Winding Machine.
  • Restraint: Sloping Conveyer.


  • The brake is simple in structure: Less parts and adjustable air-gap provide high reliability and easy maintenance.
  • Small, Light, Easy Installation: Brake directly attaches on motor, which can minimum size and weight with lolid structure.
    Fit to install under environment with limited space.
  • Low Braking Noise: With DC brake system, it does not generate any eliminate electromagnetic noise, which minimums thebraking noise.
  • Compatible to Varied Voltages: The motor is integrated with DC brake working in low noise and is applicable to a variety of power sources. The integrated DC converter accepts AC input in between 220V and 240V to convert DC output in between 80V to 110V. (For Frame#63 ~ 132M)
  • High Braking Frequency: The using of no Asbestos Lining does not only provide high wear resistance and friction under highly frequent brake but also is environment friendly.
  • All grease pre-packed double-shield rolling bearing are selected and made by reputable branded manufactures, which make replacement easily, excellent seal, and longer service life.
  • Class B Stator Insulation (For Frame# between 63 and 132M)
  1. voltage three-phase induction motor squirrel
    2. Under the new revised standard CQC
    3. Using the IEC international standard size
    4. characteristics in line with CQC and JEM standardDC brake, low noise, with the wiring changes. Applicable to a variety of power, a special internal structure, brake and strong, flexible motor brake for emergency stop and start and stop frequently exceptionally strong stamina, reverse and prevent mechanical inertia large heavy load in a short stop, superior performance.

    DC power failure brake motors Features
    1. Brake simple structure: fewer parts, high reliability, easy to adjust the air gap, and easy maintenance.
    2. Small size, light weight, easy to install: the motor and brake as a single entity, to minimize the volume and weight is also light, solid structure, small space to install.
    3. Low brake noise: mining DC brakes, electromagnetic sound, low brake noise.
    4. For a variety of voltage: brake power taps supplied by the electric motor, according to different end-line, remove the appropriate voltage box number 63-132M (AC220V-240V) to DC power by the rectifier (DC80V-100V)
    5. High Frequency brakes: Brake Linings Using Advanced non-asbestos material, resistant to high frequency of use, wear rate, and pollution-free.
    6. Selection of the world famous factory produced the Rolling and selected senior grease, dress up easily, sealed indeed, long life bearings.
    7.B pole insulated (Box No. 63 ~ 132M)

    DC motor uses power-off brake
    1. Emergency, inching stop: strapping machines, cranes, all kinds of testing machines, conveyors, machine spindle.
    2. Since high frequency, stop: Working mechanical spindle automatic unloading device operating system.
    3. To re-inertia load of short-term stop: centrifuge machines, twisting machines, textile machines.
    4. prevent dangerous: woodworking machines, textile machines, winding machines, other various machinery.
    5. restraint use: tilt conveyor.
