Details

Built as a compact FOC servo, the K7050 integrates the drive and encoder for clean, high-precision motion control.

An integrated driver board and magnetic encoder reduce wiring while keeping the motor lightweight and torque-focused.

Clear interface labeling makes it easier to wire power, CAN/RS485 communication, and UART connections during integration.

PC-based tuning supports setup, testing, and firmware updates across torque, speed, and position control modes.

Common use cases include mobile inspection robots, stabilized camera systems, LiDAR platforms, and gimbal pods.
