Siemens 1FT5066-1AC71-4EB0 Servo Motor With Brake Encoder

Siemens 1FT5066-1AC71-4EB0 is a 3‑phase brushless servo motor with brake and encoder from the 1FT5 family. This AC‑fed drive motor is built for closed‑loop positioning and includes an integrated holding brake and a shaft‑mounted encoder with 100k pulses per revolution, complemented by a tachogenerator for speed feedback. Rated at 8.0 Nm of torque and approaching 2000 rpm, the unit is designed for use with Siemens servo drives and a 600 V DC link. It is naturally air‑cooled, IP64 protected, and mounts to IM B5 frame configurations (also compatible with IM V1 and IM V3 setups). Power and signal connectors are arranged for straightforward wiring, and the shaft comes with a fitted key/groove to ease coupling to the load. The full part number 1FT5066-1AC71-4EB0 identifies a brushless servo motor with brake and encoder intended for precise, repeatable motion in automation applications.
