Description
1. Product Overview
SGMG-30ASRAF is a medium-inertia AC servo motor from Yaskawa Sigma-1 SGMG series with rated power of 3.0kW. It is designed for three-phase 200V power supply and runs at a rated speed of 1500rpm. Equipped with multi-turn absolute encoder, the motor features standard solid output shaft without electromagnetic brake, standard flange mounting structure and natural air cooling, as well as factory-fitted shaft oil seal. This model must be matched with SGDM-30ADA servo drive of the same series. Widely applied in CNC machine tools, automated production lines, textile machinery, auxiliary injection molding equipment and customized automatic equipment, it is a classic legacy servo motor of Yaskawa.
Model code explanation: SGMG stands for medium-inertia motor series; digit 30 refers to 3kW power rating; letter A means 200V voltage class; S denotes multi-turn absolute encoder; R represents solid shaft with oil seal; A indicates no brake device; F stands for standard flange and wiring specification.
2. Electrical Specifications
Its continuous rated output power is 2900W, rated input current is 23.8A and continuous rated torque reaches 18.6N·m with peak overload capacity up to 300% of rated torque. The multi-turn absolute encoder retains origin data via external backup battery, eliminating homing operation after power restart. Insulation class is Class F; dielectric strength withstands AC1500V for one minute and insulation resistance exceeds 10MΩ under DC500V test.
3. Mechanical Specifications
The motor adopts standard IEC flange mounting available for both horizontal and vertical installation. The solid output shaft comes with built-in oil seal to prevent dust and liquid ingress. Cooling type is natural convection without external cooling fan. Protection grade is IP67 except the shaft extension end. Operating ambient temperature ranges from 0℃ to 40℃ with relative humidity between 20% and 80% non-condensing, applicable below altitude of 1000 meters and with low V15 vibration grade for precision positioning occasions.
4. Matching Drive & Application
SGDM-30ADA servo drive is the exclusive matching driver unit for this motor. Typical application fields include CNC milling machines, machining center retrofitting, injection molding servo renovation, printing equipment and various automated processing machinery.
