Overview
The MyActuator L-5015 is a compact direct-drive BLDC servo with integrated driver and magnetic position sensor. It supports torque, speed, and position closed-loop control with S-curve profiling over CAN or RS485, and offers built-in over-temperature/over-voltage/over-current protection plus dual (driver & motor) temperature monitoring. Typical uses include pipeline and service robots, steering gear heads, industrial turntables, gimbals, laser LiDAR, and inspection robots.
