Siemens 1FT6105-8WF71-4AG1 AC Servo Motor 210V

Siemens SIMOTICS S synchronous servo motor 1FT6105-8WF71-4AG1 is a water-cooled member of the 1FT6 family designed for high-precision axis control in automation, configured for 210 V AC operation. The WF71 variant delivers about 85 Nm of nominal torque at up to 3,000 rpm, making it suitable for medium- to high-torque positioning and fast-cycle tasks. It uses an incremental encoder with 100K counts per revolution, providing reliable feedback for closed-loop motion control. The drive end accommodates a power and signal connector with the outgoing connector oriented axially, simplifying harness routing in compact installations. This motor is mounted in the IM B5 family (compatible with IM V1 and IM V3 drive arrangements) to align with Siemens drive systems and standard cabling schemes. The combination of water cooling, 210 V nominal supply, 85 Nm torque, and 3,000 rpm speed makes this variant appropriate for demanding servo applications within automated equipment where consistent performance and precise positioning are required. As part of Siemens’ SIMOTICS S line, this 1FT6 servo motor is designed to be used with compatible Siemens servo drives to achieve accurate speed, torque, and position control in integrated automation solutions.
