Product description

The Siemens 1FT6105-8SF71-4SH0 is a SIMOTICS S synchronous servo motor engineered for high-performance motion control applications requiring holding torque. This motor delivers 65 Nm of torque at 3000 rpm, equipped with force ventilation for continuous operation. It features an IM B5 mounting, axial power and signal connectors, a multi-pole resolver (P=4) for feedback, and a smooth shaft with circular runout tolerance N. Critically, this model includes a holding brake for secure positioning when power is removed. It is protected by a labyrinth seal, achieving an IP64 rating.

This servo motor is well-suited for vertical axis applications, robotics, automated assembly, and machine tools where maintaining position without power is crucial. Industries such as material handling, printing, and packaging benefit from its precise control and holding capabilities.
