Siemens 1FT6041-4AF71-3AG0L Servo Motor With Alpha Planetary Gearbox

Siemens 1FT6041-4AF71-3AG0L is a 1FT6‑series SIMOTICS S synchronous servo motor paired with an Alpha planetary gearbox for precise, high‑torque motion in automation and robotics. The motor is a 4‑pole servo unit with a rated speed of 3,000 rpm and a nominal torque around 2.5 N·m, delivering about 0.68 kW of continuous power at the optimum operating point. It uses a 2048‑point incremental encoder (sin/cos) for accurate feedback and is designed for natural cooling with IM B5 mounting. The Alpha planetary gearbox multiplies output torque and improves stiffness for dependable positioning, making this combination well suited to pick‑and‑place, packaging lines, CNC axes, and robotic feeding applications. Built for use with standard high‑voltage servo drive systems, this motor‑gearbox pair provides smooth torque delivery and repeatable speed control across a range of workloads while maintaining compact packaging and reliable long‑term performance in automated environments.
