Direct Drive Brushless Motors

   

Hi-Torq Brushless Direct-Drive Servomotor
The Hi-Torq series of brushless servomotors pack a remarkable amount of torque into a low profile package, making them perfect for your direct-drive applications. These motors, when driven by the same FlexMax drives you use with the PacTorq and PowerTec series motors, provide a superior alternative to many conventional gearbox and belt solutions to your motion control applications.


Where do I use Hi-Torq?

    Use Hi-Torq motors ...
    • ... for gearless uses where zero backlash is required.
    • ... on machines where very high torque is needed in a small space.
    • ... where maintenance is a problem (built into machinery).
    • ... when extremely smooth low speed torque is needed.
    • ... where shaft mounting, low profile drive means is necessary.

Features & Benefits

  • Low overall weight compared to motor/gear combinations
  • Extremely high accuracy with drives capable of using the sinusoidal encoder
  • Completely enclosed feedback devices
  • Conventional servo connectorized power and feedback wiring
  • Low compliance bolted shaft-mount provisions
  • Input shaft can be keyed if desired
  • Hall effect commutation output built in, plus...
      ... sinusoidal encoder or optional resolver (E340 series)
      ... digital encoder or optional resolver (E430 series)
