SGM-04A3NT12 belongs to Yaskawa classic Sigma-I first-generation permanent magnet AC servo motor, rated power 400W (0.4kW), 200V AC voltage grade, original Japanese standard servo unit. The suffix NT stands for industrial standard plug-in connector wiring structure (separate metal aviation plugs for power cable and encoder cable, instead of flying lead wire), standard keyed solid output shaft without built-in electromagnetic brake.

Rated three-phase input voltage AC200V; rated continuous operating current is 2.6A RMS, continuous rated torque reaches 1.27N·m, instantaneous peak overload torque is three times rated torque for short-period acceleration and heavy-load startup. Rated rotating speed is 3000rpm, maximum allowable no-load speed 4500rpm. Equipped with 2048PPR A/B/Z differential incremental line-driver encoder for closed-loop position feedback to guarantee high positioning precision; motor insulation class is Class B complying with international electrical standards.

Adopts standard 60mm square flange mounting dimension; output shaft diameter 14mm with integrated flat key slot for coupling assembly connection. Totally enclosed motor shell with IP64 protection rating, natural air cooling design without auxiliary cooling fan; net weight is around 1.35kg, compact body for limited installation space layout.

Permitted continuous working ambient temperature ranges from 0℃ to +40℃; long-term storage temperature spans -20℃ to +85℃ under power-off status. Applicable working relative humidity 20%~80% with no condensation on motor surface; avoid environments with corrosive gas, dense dust and oil mist, rated for installation below 1000m altitude, derated power required for installation over 1000m height.

Perfectly matched with Yaskawa SGDA-04AS, SGDS-04A 200V-grade SERVOPACK servo drivers to form complete servo control system. Widely used in medium-load precision automation equipment: automatic dispensing machines, labeling machinery, small feeding modules, miniature CNC auxiliary feed axes, precision index fixtures and automatic test equipment.

Stable low-speed operation with low vibration and running noise, excellent instantaneous overload capacity and strong anti-electromagnetic interference performance; mature Sigma-I classic structure with stable long-term running reliability, widely used in conventional medium-precision industrial automation motion control projects.
