Яскава СГМАВ-08A3A2C belongs to the Sigma‑V (Σ‑V) SGMAV low‑inertia servo motor family, optimized for applications requiring rapid acceleration and deceleration with minimal settling time. With a rated output of 0.75 кВт (750 Вт) at 3000 rpm and a rated torque of 2.39 Нм, it fits the “08A” frame in the SGMAV lineup, offering a strong torque‑to‑inertia ratio in a compact housing. The 200 V класс, 3‑phase permanent‑magnet synchronous design provides high efficiency, smooth torque, and excellent dynamic response when paired with a matching Sigma‑V servo drive (typically SGDV‑5R5A‑series amplifiers).
As a low‑inertia motor, СГМАВ-08A3A2C uses a lightweight rotor to reduce moment of inertia, enabling millisecond‑level acceleration and deceleration suitable for short‑stroke, high‑cycle positioning tasks such as pick‑and‑place, electronic assembly, маркировка, and small indexing tables. The Sigma‑V platform supports high‑resolution encoders (commonly 20‑bit incremental or absolute), delivering precise speed and position feedback and allowing very tight servo tuning with reduced overshoot and settling time. The “A3A2C” code indicates specific options for shaft, кодер, and brake configuration; typical variants include a straight shaft with key, oil seal, and a standard encoder suitable for most general‑purpose motion systems.
According to Yaskawa’s Sigma‑V SGMAV family data, 08A‑class motors operate from a 200 V supply with around 5.3 Arms rated current and can reach up to 6000 rpm maximum speed for short‑term operation, offering up to 7.16 Nm peak torque for acceleration and disturbance rejection. The motor’s protection is typically IP65 on the shaft side with an oil seal, making it suitable for industrial environments with dust and occasional splashes when correctly installed. Compact dimensions and low weight simplify mounting on small machines, while standard flange patterns and shaft dimensions ensure compatibility with gearboxes and couplings used in packaging, печать, semiconductor, and general automation equipment.
СГМАВ-08A3A2C is widely available as a new or refurbished spare part, and many suppliers highlight its compatibility with existing Sigma‑V systems as a drop‑in replacement for failed motors in CNC machines and automated lines. When used with a matched Yaskawa Sigma‑V servo drive, it supports advanced functions such as autotuning, подавление вибрации, and networked control via MECHATROLINK or other fieldbuses, enabling high‑performance multi‑axis systems.
