YASKAWA ELECTRIC SGMG-05A2AB AC Servo Motor

YASKAWA SGMG-05A2AB Sigma II 0.45kW 1500rpm medium inertia AC servo motor without brake matched with SGDB-05ADG for CNC machine spare replacement.

Description

YASKAWA ELECTRIC SGMG-05A2AB AC Servo Motor
Serial No: B0074E047970203

Overview

The YASKAWA ELECTRIC SGMG-05A2AB is a medium-inertia AC servo motor belonging to the legacy Yaskawa Sigma II series. The string B0074E047970203 is the unique serial number of this unit, used for traceability only and not part of the catalog model. Rated power is 0.45 kW, 200 V class, rated speed 1500 rpm. It is equipped with an incremental encoder, straight shaft, without holding brake. The matching servo amplifier is SGDB-05ADG. This series is discontinued and supplied only as spare parts for existing machine retrofits and maintenance.

Features

The YASKAWA ELECTRIC SGMG-05A2AB features medium rotor inertia, delivering stable low-speed operation and good repeat positioning accuracy.SGMG-05A2AB adopts separate power and encoder connectors with incremental encoder feedback. Standard version without brake; the braked variant is SGMG-05A2ABC. Solid mechanical structure and strong overload capacity, widely adopted on CNC machine tools. Direct replacement requires the full catalog model SGMG-05A2AB; the serial number B0074E047970203 is for unit identification.

Specs

Device Type: AC Servo Motor Model: YASKAWA SGMG-05A2AB Serial: B0074E047970203 Brand: Yaskawa Electric Series: SGMG Sigma II Rated Output: 0.45 kW Rated Voltage: 200 V AC 3-phase Rated Speed: 1500 rpm Rated Torque: 2.84 N·m Rated Current: 3.8 A Encoder: Incremental encoder Shaft: Straight shaft, no keyway Brake: None Matching Drive: SGDB-05ADG Mounting: Flange mount Operating Temperature: 0 ~ +40°C Status: Obsolete, discontinued production

Principle

The YASKAWA ELECTRIC SGMG-05A2AB permanent magnet synchronous servo motor receives three-phase driving current from the SGDB servo amplifier. The encoder feeds rotor position and speed back to the drive to form closed-loop vector control. The amplifier adjusts output current to precisely follow position, speed or torque commands for machine axis motion.

Applications

The YASKAWA ELECTRIC SGMG-05A2AB serves as feed axis motor for CNC lathes, machining centers, grinders, special automation machines and packaging lines. The YASKAWA ELECTRIC SGMG-05A2AB is stocked as spare part for legacy equipment overhaul. For new projects, the Sigma-7 SGM7G series is the recommended upgrade.
