Direct-Drive Motors

Direct-Drive Motors:

Our direct-drive mounts and gimbals are designed, fabricated, and assembled at our Adrian, Michigan campus. We manufacture our own direct-drive motors for each mount and gimbal to provide high precision tracking and pointing accuracy for demanding client applications all over the world. Direct-drive motors means that there are no gears to cause backlash or periodic error while slewing and tracking. With the high-resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error or have any backlash at all, but the mount will be able to counter against wind gusts. The direct-drive motors can move the telescope at incredible speeds for tracking satellites, or just to minimize target acquisition time.

  • L-series mounts utilize high resolution incremental optical ring encoders and the CDK700 and CDK1000 systems include absolute optical ring encoders
  • Stable satellite tracking for LEO and beyond
  • Slew speeds > up to 50 degrees/second
  • 115VAC 20A input: No need for 3-phase power or generators (L-Series mounts can accept either 120VAC/20A to 240VAC/10A input)
