Planetary joint module rated at 4 N·m and 250 rpm, with CAN FD / CAN communication.
Catalog specifications · page 15Application guidance is based on the listed hardware and development resources. Confirm the software, sensors and integration your project needs.
Calculate load, inertia, thermal conditions and duty cycle. Confirm bearings, mounting flanges and mechanical differences between paired models before treating them as interchangeable.
Check the torque-speed curve at your operating point, inertia, braking and bearing loads. Validate the complete mechanism at the intended speed.
