SGM-08A3NT12 is a 750W permanent magnet AC servo motor of Yaskawa original Sigma-I series with three-phase AC200V specification. Code A stands for 200V voltage grade, digit 3 refers to 2000PPR incremental encoder with line driver output, NT means side outgoing aviation plug wiring without fixed flying leads, and suffix 12 is customized factory specification; no built-in brake is equipped for this model.

Rated power is 750W with three-phase AC200V power supply, rated working current is 4.4A RMS. Continuous rated torque is 2.39N·m and short-time peak torque can reach three times rated torque to meet instant startup and heavy-load acceleration. Rated rotation speed is 3000rpm and maximum permissible no-load speed is 4500rpm. The fitted incremental encoder delivers A/B/Z differential pulse signals for closed-loop position control, and winding insulation complies with Class B standard.

It adopts standard 80mm square flange installation structure, output shaft diameter is 19mm with standard flat key and circlip for coupling assembly. Fully enclosed motor housing reaches IP64 protection level with natural air cooling design without auxiliary fan. Net weight of the motor is approximately 2.2kg with compact body structure.

Continuous operating temperature ranges from 0℃ to +40℃, and storage temperature is from -20℃ to +85℃ under power-off condition. Working relative humidity is controlled between 20% and 80% without condensation on the motor surface. Avoid installation locations with corrosive gas, oil mist and heavy dust; proper power derating is needed when used above 1000 meters altitude.

Compatible with Yaskawa SGDS-08A and SGDA-08AS 200V-class servo drivers to form complete servo control system. It is commonly used for medium-load automation equipment including automatic packaging equipment, precision feeding machinery, small rotary indexing tables, dispensing devices and auxiliary feed axes of mini CNC machines.

Stable low-speed operation with low vibration and noise, excellent overload resistance and reliable anti-interference performance. Classic mature Sigma series structure ensures long-term stable service in industrial precision motion control scenarios.
