Description:
The MyActuator RMD-L-4015-20T V3 is a high-performance micro brushless DC out-rotor servo motor designed for applications demanding high torque in a compact form factor. With direct drive capability and a nominal torque of 0.22 N·m (peak torque 0.49 N·m), this actuator delivers precision and efficiency across a wide range of robotic, automation, and mechatronic projects.
Engineered with a large diameter and multiple pole pairs, the motor achieves a nominal speed of 520 RPM and supports instantaneous speeds up to 1010 RPM, providing responsive performance in dynamic environments. The integrated 14-bit magnetic encoder ensures accurate position feedback, while the torque open loop, speed loop, and position loop control modes allow flexible motion control tailored to your system.
The actuator operates efficiently within a 12–24V voltage range and communicates seamlessly through RS-485 and CAN BUS protocols, supporting baud rates from 9600 to 115200. Its robust design accommodates temperatures from -20°C to 80°C, with a maximum demagnetization temperature of 120°C, ensuring reliable operation in diverse industrial and research settings.
Additional features include an S-curve function for smooth motion, an ID switch for easy device management, and a built-in temperature sensor for safe operation. Lightweight yet durable at 120 grams, the RMD-L-4015-20T V3 is perfectly suited for compact robotics, automated mechanisms, and precision mechatronics applications.
