ServoBelt Product Announcement

A new line of linear modules using our patent pending ServoBelt drive technique is now available. Zero backlash, high stiffness and industry leading repeatability make this technology a true contender to replace linear motors in demanding applications requiring high speed and low settling time.

At the heart of the technology is a static bonded lower belt that meshes with the upper dynamic belt so that the active belting under tension is only a few inches long. Servo tuning can have much higher gains than conventional belts, because stiffness is high and does not change throughout the travel.

BENEFITS

  • Actuators and stages are configurable as multi-axis Cartesian and gantry robots.
  • Modules may be purchased as single axis elements for your OEM equipment or as a completely integrated multi-axis robot with amplifiers, cables and optional linear encoders.
  • Multiple carriages can be supplied for independent motions on the same axis, and dual motor carriages are available to double our standard linear forces.
  • Five motor choices in both NEMA 23 and NEMA 34 frame sizes for easy configuration, or units are available for mounting of third party motors.
  • All chassis are based on Bosch T-slot extrusions for ease of integration and a wide array of mounting hardware.
  • Unlimited length for large format applications.

FEATURES

  • Accelerations in excess of 4g.
  • Speeds to 5m/s.
  • High performance polyurethane/steel reinforced belt
  • Single motor peak forces to 880N, continuous forces to 300N.
  • Out of the box accuracy to ±60µm.
  • Unidirectional repeatability to ±10µm, bi-directional to an amazing ±40µm.
  • All bearings Lubed-for-Life, no maintenance required.
  • Direct-Drive three phase servo motor available in five sizes.
  • 16,000 and 20,000 CPR rotary encoders standard.
  • Optional Renishaw linear encoder for 10x better repeatability and accuracy
  • Optional integrated limit sensors, infinitely adjustable
  • Anodized aluminum construction with SS hardware
