The YASKAWA SIGMA-7 SERVO MOTORS 50W SGM7J-A5AFA6S represents the pinnacle of compact servo motor engineering, designed for applications requiring high torque density, low inertia, and exceptional dynamic response. This model, part of the renowned Sigma-7 family, delivers a rated speed of 3000 min⁻¹ and a maximum speed of 6000 min⁻¹, making it ideal for pick-and-place, packaging, and assembly machinery. Its 50W power rating is perfectly matched for small-axis control, while the 20-bit encoder ensures sub-arc-minute positioning accuracy. The motor features a 24V DC holding brake and a straight keyway shaft, providing reliable performance in vertical or safety-critical installations. With a protection rating of IP67 (excluding shaft end), it withstands harsh industrial environments. The SGM7J-A5AFA6S is fully RoHS compliant and offers a compact frame size (60 mm square flange) for space-constrained designs.
