Product description

The Siemens 1FT6044-4AK71-4SH0 is a SIMOTICS S synchronous servo motor designed for applications requiring holding torque when unpowered. It delivers 5.0 Nm of torque at 6000 rpm and is naturally cooled. This motor is configured for IM B5 mounting (IM V1, IM V3) with axial power and signal connectors. It features a multi-pole Resolver (P=2) for feedback, a smooth shaft, and a labyrinth seal for IP64 protection. Importantly, this model includes a holding brake.

This servo motor is ideal for vertical axis applications, robotics, and any automation system where maintaining position during power loss is critical. The integrated holding brake provides safety and positional stability. Its IP64 rating offers protection against dust and splashing water.
