Product Overview
JY-SM 60/80 servo motors are designed for battery-powered mobile robots. They run directly on a 48 V DC bus, fit compact 60 mm and 80 mm flanges and deliver 3× overload for start-up and ramp peaks.
Eight standard models cover 200–1,500 W and 0.64–4.77 N·m rated torque (up to 14.31 N·m peak). A multi-turn magnetic absolute encoder keeps the position through power-off, so the vehicle needs no homing after power-up.
Typical uses are drive-steering units, differential drives, lifting mechanisms and four-way shuttles. A holding brake is optional (suffix B), and each motor has a matching 48 V servo drive with CANopen or EtherCAT.
