Yaskawa Electric Corporation SGM7J-01AFA21 Servo Motor

The Yaskawa SGM7J-01AFA21 Servo Motor is a 100 W AC servo motor in the Sigma-7 (SGM7J) family designed for compact, high-precision motion control within Sigma-7 AC servo drive systems. It operates at 200 VAC with a rated current of 0.85 A and delivers a rated torque of 0.318 N·m at up to 3000 RPM in a 3‑phase configuration, featuring a high-resolution encoder for accurate feedback and a straight shaft on a flange-mount housing with self-cooled operation. This motor is commonly used in small CNC machines, electronics assembly equipment, pick-and-place systems, and light-duty automation lines, and is suitable for electronics manufacturing, inspection equipment, small robotic systems, and conveyor automation where repeatable positioning, precise speed control, and reliable torque contribute to consistent production quality. Common replacements include Yaskawa SGM7J-01AFA, Yaskawa SGMJV-01ADA21, and Yaskawa SGMAH-01AAA41.
