Yaskawa Electric Corporation USAREM-A6CYR12 AC Servo Motor

The Yaskawa USAREM-A6CYR12 is a compact brushless AC servo motor in the USAREM (R-Series / Minertia) class designed for high-speed, precise axis motion in Motoman robot axes (R, B, T) and CNC automation equipment. It uses an UTMAI-B12AD3A absolute encoder for feedback, enabling reliable position sensing and closed-loop control at up to 3000 RPM. Rated power sits in the 50–100 W class for the A6 frame, with a voltage class of approximately 100–200 VAC, and it features a flange-mount, low-inertia design for rapid acceleration and accurate positioning, all within a totally enclosed, self-cooled package weighing about 1.7 lb. Common replacements include USAREM-A6CYR11 and SGMJV-01ADA21 for retrofits and maintenance, highlighting its role in robotic welding, material handling, semiconductor equipment, and CNC machinery where coordinated axis motion and encoder feedback are essential.
