The Yaskawa SGMAH-A5A2A-YR21, part of the Sigma II series, is designed as an AC servo motor for precision applications. It is rated for an output power of 50 watts, while continuously providing a torque of 0.159 N·m. The motor can deliver a peak torque capacity reaching 0.477 N·m, making it suitable for applications requiring high responsiveness.
Its nominal current draw is configured at 0.64 A (rms), with the capability to handle transient currents up to 2.0 A (rms). The motor typically operates at a standard speed of 3000 revolutions per minute (min⁻¹) and can reach a maximum operational speed of 5000 min⁻¹. A notable torque coefficient of 0.268 N·m/A (rms) signifies efficient torque production concerning current supply.
The rotor moment of inertia is specified at 0.022 × 10⁻⁴ kg·m², allowing for precise control. It supports an allowable load inertia ratio of up to 20 times the rotor inertia, facilitating effective matching with various load conditions. This unit also boasts a power performance rating of 11.5 kW/s and is capable of a rated angular acceleration of 72,300 rad/s².
For feedback, the motor is equipped with a standard 13-bit incremental encoder. An optional upgrade is available for a 16-bit incremental or absolute encoder, enhancing measurement precision. The housing offers a protection rating of IP55, ensuring reliable performance in environments that require resistance to dust and water, except at the shaft opening.
