Siemens 1FT6105-8AB71-1AB0 is a permanent-magnet synchronous servo motor from the SIMOTICS S 1FT6 series. This version combines a standstill torque of 50 Nm at 100 K with a rated speed of 1,500 U/min, making it suitable for controlled machine axes, positioning tasks and motion-control applications requiring high torque. The Siemens configuration manual specifies a rated torque of 41 Nm, a rated current of 14.5 A and eight poles for winding 8AB7. The maximum mechanically permissible speed is 5,600 U/min, and maximum torque is 140 Nm. Natural cooling simplifies installation because no separate external fan is required. This version supports mounting arrangements IM B5, IM V1 and IM V3 and includes a sin/cos 1 Vpp incremental encoder with 2,048 S/R, a keyed shaft and a holding brake. Power and signal connections use plug connectors with a transverse outlet to the right. The labyrinth seal provides an IP64 protection rating for this variant. With the holding brake fitted, the manual specifies a motor weight of 44 kg and a moment of inertia of 199 × 10⁻⁴ kgm². Encoder resolution, the holding brake and connector orientation are particularly important in replacement procurement because these features vary within the series. Before installation, compare the complete order number, encoder version, shaft design, brake, mounting position and connector orientation with the existing axis. This avoids fitting a mechanically similar 1FT6105 variant with a different encoder or shaft. The motor is intended for industrial spare-parts and retrofit projects that require the exact order number 1FT6105-8AB71-1AB0.
