The Siemens 1FT6064-6WF71-4SA0 is a 6-pole, permanent-magnet synchronous motor designed for high-dynamic performance in demanding environments. Unlike standard naturally cooled motors, this model utilizes water cooling, allowing it to maintain high torque output (16.2 N.m) in a compact frame size without overheating.
This specific configuration features a multi-pole resolver (P=3) for robust position feedback and a smooth shaft (without feather key) to ensure maximum rotational accuracy and balance at high speeds. With an IP64 protection rating (labyrinth seal), it is built to withstand industrial contaminants. As a spare part item, it is the primary choice for maintaining and repairing high-end CNC machinery and automated production lines.
