Yaskawa SGMAH‑03DAAA61 200V 300W AC Servo Motor
The Yaskawa SGMAH‑03DAAA61 is a high‑performance AC servo motor from the SGMAH series, delivering 300 W rated power at 200 V input. Designed for applications requiring precise speed, position, and torque control, this motor incorporates a 13‑bit incremental encoder (resolution 2048 P/R) to provide accurate feedback to the servo drive. Its compact size and high torque‑to‑inertia ratio make it ideal for fast indexing, robotics, and electronic assembly machinery.
Electrical and Mechanical Specifications
Rated torque is 0.955 Nm, with a maximum torque of 2.86 Nm. The motor achieves a rated speed of 3000 min⁻¹ and a maximum speed of 4500 min⁻¹. Rated current is 1.6 A (RMS) at 200 V, while maximum current reaches 4.8 A. The rotor inertia is 0.33 × 10⁻⁴ kg·m², enabling rapid acceleration and deceleration cycles. Insulation class F (155 °C) ensures durability under continuous operation.
The motor frame size is 40 mm square (40 × 40 mm flange) with a shaft diameter of 8 mm and a keyway. The overall length (excluding shaft and connector) is 70 mm, and the shaft length is 25 mm. Weight is approximately 0.75 kg. The housing is rated IP65 (excluding shaft seal), offering protection against dust and water jets, suitable for washdown or dusty environments.
Encoder and Feedback System
A 13‑bit incremental encoder (model: UTBIH) provides 2048 pulses per revolution after quadruple multiplication. This yields a real‑time position resolution of 0.176°, sufficient for most pick‑and‑place and positioning tasks. The differential line driver outputs (A, B, Z phases) allow cable lengths up to 20 meters without signal degradation. Optional battery‑less absolute encoder variants are not present on this model, ensuring simple commissioning with Yaskawa Sigma II or Sigma‑5 drives.
Compatible Drives and Wiring
The SGMAH‑03DAAA61 operates with Yaskawa SGDH, SGMDS, or SGDV series servo drives configured for 200 V class and 300 W rating. The motor power connector (model: CM‑X1) uses a 4‑pin locking design (U, V, W, ground), while the encoder connector (CM‑X2) uses a 10‑pin mating connector. Standard cable lengths of 3, 5, or 10 meters are available. Dynamic braking is internal to the drive; the motor does not include a holding brake. For vertical load applications, an external brake is recommended.
Performance Characteristics
The speed/torque curve is nearly flat up to rated speed, with continuous operation possible in the entire torque range as long as RMS current does not exceed 1.6 A. Torque ripple is less than ±5% of rated torque. The motor can withstand up to 10 Gs of shock and 1.5 Gs of vibration (10‑500 Hz). Operating ambient temperature range is 0‑40 °C, with non‑condensing humidity 20‑80%.
Typical Applications
This servo motor is found in CNC tool changers, semiconductor handling systems, medical pump drives, and conveyor diverters. Its small footprint and high efficiency (≥85%) reduce heat buildup in compact machinery. Compliance with CE, UL, and RoHS standards ensures global acceptance.
