The Yaskawa SGM7A-04AFA21 servomotor from the Sigma 7 series is a low-inertia rotary motor built for high-performance tasks. Operating at an input voltage of 200 V, it reaches speeds of up to 3000 RPM, enabling rapid response and accurate control. Its rated torque stands at 1.27 Nm, delivering reliable power for a variety of applications.

The unit is equipped with a 24-bit incremental encoder, which contributes to its precision in motion control. This encoder aids in fine-tuning positioning and velocity feedback, ensuring smooth operation. The design features a straight shaft that measures 30 mm in length and has a diameter of 14 mm without a key, providing flexibility for coupling without additional components. The flange diameter of the motor is 70 mm, facilitating easy integration into existing setups.

This servomotor supports a maximum allowable load inertia of 20 times the motor's inertia. This characteristic allows it to handle dynamic loads effectively, maintaining operational stability in varied conditions. The Yaskawa SGM7A-04AFA21 is ideal for applications where quick maneuvers and precise positioning are critical.
