Product description

The Siemens 1FT6108-8AB71-1AH0 is a SIMOTICS S synchronous servo motor designed for general automation tasks requiring reliable incremental feedback. This motor delivers 70 Nm of torque at 1500 rpm and is naturally cooled. It features an IM B5 mounting and an axial connector for power and signal, oriented towards the right (Transverse right). The feedback system is an incremental encoder with sin/cos 1 Vss signals and 2048 S/R resolution. The shaft is smooth with a circular runout tolerance of N, and the motor includes a holding brake. It is sealed to IP64 with a labyrinth seal.

This servo motor is suitable for a wide range of applications, including conveyor systems, automation machinery, and moderate-duty machine tools where incremental feedback is sufficient for control. The holding brake provides secure positioning when power is off.
