Yaskawa SGMAH-04AAF41 Sigma II Servo Compact 0.4kW Motor

Overview

The SGMAH-04AAF41 servo motor delivers 0.4 kW of output power with fast response and high accuracy.
Yaskawa designed this Sigma II motor for compact automation platforms that need fast motion and clean feedback.

Key Technical Highlights

• The SGMAH-04AAF41 outputs 1.27 N·m torque for stable and efficient motion.
• The motor reaches 3,000 RPM rated speed and 5,000 RPM maximum speed for high-cycle tasks.
• The system runs on a 200 V AC single-phase power supply for easy integration.
• A 13-bit incremental encoder improves positioning accuracy in automated systems.
• The motor carries an IP55 rating to protect against dust and moisture.
• Total weight is 2.27 kg (5.00 lbs) for easy installation and transport.

Performance & Environment

• It supports ambient temperatures between 0°C and 40°C in non-condensing conditions.
• Storage temperatures range from -20°C to 85°C for safe warehouse management.
• The Sigma II design ensures stronger noise resistance in industrial automation fields.
• The straight shaft with keyway ensures stable torque delivery under continuous load.
• The flange mount enables quick alignment and simple mechanical assembly.

Installation Guide

• Mount the motor through its flange interface and align the shaft before tightening bolts.
• Connect the main power to a stable 200 V AC single-phase source.
• Keep encoder cables away from high-current wiring to reduce noise.
• Verify motor rotation direction during the first low-speed test.
• Add shielding or ferrite rings in strong EMI environments for encoder stability.

FAQ — Experience-Based Answers

• How do I confirm encoder quality?
  Rotate the shaft slowly and check pulse signals on an oscilloscope to confirm clean A/B output.
• How much torque reserve should I plan?
  Maintain at least twenty percent torque margin for long life and low thermal stress.
• How do I lower vibration at high RPM?
  Use a flexible coupling and check alignment to reduce transfer forces.
• Which drive series works best with this motor?
  Pair it with modern Yaskawa amplifiers that support 13-bit encoder input.
• How do I protect encoder signals on long cable runs?
  Use shielded twisted-pair cables and avoid routing near power lines.
