YASKAWA SGMAH-02AAA61D-OY 200W Servo Motor

The YASKAWA SGMAH-02AAA61D-OY is a 200-watt AC servo motor from the Sigma II series, designed for precision motion control in compact industrial applications. Operating on a 200V AC power supply, this motor provides high torque density and smooth rotation, making it suitable for small robotics, electronic assembly, and packaging machinery.

Technical Specifications

The SGMAH-02AAA61D-OY delivers rated output of 200W at a rated speed of 3000 RPM. The rated torque is 0.637 Nm, with a maximum instantaneous torque of 1.91 Nm. The rotor inertia is 0.143 × 10⁻⁴ kg·m², providing excellent dynamic response. The motor incorporates a 13-bit incremental encoder (8192 pulses per revolution) for precise position and speed feedback. The insulation class is Class B, and the motor housing is rated IP65 for dust and water protection except on the shaft. The holding brake option is not included in this model (standard configuration). The motor weighs approximately 0.8 kg and has a flange size of 40 mm square.

Features and Design

The SGMAH series features a medium-inertia rotor optimized for applications with varying loads. The motor's compact frame allows installation in tight spaces. The encoder provides high-resolution feedback for smooth motion even at low speeds. The motor includes a 24V DC holding brake (optional on some variants) for position holding when power is off. The -OY suffix indicates specific customizations for Yaskawa OEM applications, including special shaft or connector configurations. The motor is designed for use with Yaskawa SGDH series servo amplifiers, forming a complete Sigma II servo system.

Applications

This 200W servo motor is ideal for small pick-and-place machines, electronic component insertion equipment, medical device automation, laboratory robotics, and small conveyor drives. The combination of compact size and high torque makes it suitable for applications where space is limited but precise motion is required. The motor is commonly used in semiconductor manufacturing equipment, small CNC machines, and packaging machinery.

Integration and Installation

The SGMAH-02AAA61D-OY connects to Yaskawa SGDH servo drives using dedicated power and encoder cables. The motor should be mounted on a rigid surface to minimize vibration. Proper grounding and shielding are essential for noise immunity. The motor shaft accepts standard couplings or pulleys, with a keyway provided for positive torque transmission. The operating temperature range is 0°C to 40°C, with a maximum humidity of 90% non-condensing. The motor should be protected from dust, oil, and water spray to maintain the IP65 rating.

Compatibility and Maintenance

The SGMAH-02AAA61D-OY is compatible with all Sigma II SGDH servo amplifiers rated for 200W to 400W output. The motor requires no routine maintenance other than periodic cleaning and inspection of cables and connectors. The encoder battery (if used for absolute positioning) should be replaced every 1-2 years. Replacement parts including cables, connectors, and shaft seals are available through Yaskawa distributors. The motor is no longer in active production but is widely available as a replacement for existing Sigma II systems.
