Choosing this model

Read the product documentation

Sourcebotics selection notes, based on the published documentation.

Application fit

  • Compact joint designs already dimensioned around the classic AK80-9 KV100 and its 9:1 planetary transmission.
  • Projects comparing continuous torque, speed and thermal mounting requirements rather than selecting by peak torque alone.

Integration planning

  • Specify classic AK80-9 KV100 on the bill of materials. AK80-9 V3.0 is a separate revision with its own specification; do not combine its peak torque or mass with this listing.
  • Request the classic revision’s CAN/UART protocol, firmware and connector pinout before reusing a controller written for another AK-series actuator.
  • Confirm the mechanical drawing, encoder reference procedure, power supply and thermal mounting for the exact motor and driver revision.

Selection considerations

  • Use the listed 9 N·m rated and 18 N·m peak values for this classic entry; ask for the applicable duty and cooling conditions for your torque-speed cycle.
  • When replacing an existing actuator, compare mounting, calibration and command scaling as well as gear ratio; a shared model family does not establish interchangeability.

FAQ

Which configuration should be quoted?

Specify the classic KV100 revision and whether the driver board and cables are included.

What should be agreed before ordering?

Provide torque–speed duty cycles and cooling conditions; size continuous operation against rated rather than peak torque.
