SD-L01
The SD-L01 is SunDynamics' first commercially available high-torque actuator — a fully integrated unit combining a PMSM motor, cycloidal gearbox, and servo driver in a single compact pancake form factor. It delivers 68 Nm of continuous torque and a 204 Nm peak, making it well suited to applications where size, torque, and mass are critical constraints.
