Product Overview
JY-SM130 servo motors bring 1.5–3 kW of servo power to a 48 V platform. They give heavy drive-steering units, hydraulic lifts and tow tractors ample torque, with peak torque up to 43 N·m and IP65 protection (shaft seal IP54).
The 2000 rpm model, JY-SM130-300I-20, offers higher torque to match large-ratio gearboxes directly. All models use a 2500 ppr incremental magnetic encoder; a holding brake is optional (suffix B). The 2 m leads connect directly to the drive.
The JY-SD series of 48 V low-voltage servo drives covers motors from 200 W to 3 kW. Depending on the drive, communication is CANopen, EtherCAT or RS485 + pulse (suffix C, E or L).
