Product description

The Siemens 1FT6041-4AF71-4EG1 is a SIMOTICS S synchronous servo motor designed for advanced automation tasks. It features natural cooling, an IM B5 mounting configuration, and a rated torque of 2.5 Nm at 100K. This motor is equipped with an Absolute encoder (EnDat 2048 S/R) for highly accurate positioning, which results in a 10% derating. It has a smooth shaft with circular runout tolerance N, no holding brake, and a vibration severity grade of N. The Gamma sealing ring provides IP65 protection.

This servo motor is ideal for applications demanding precise absolute positioning and high environmental resistance, such as in robotics, semiconductor manufacturing, and sophisticated machine tools. The IP65 rating ensures protection against dust and water jets, making it suitable for a wide range of industrial environments.

Stanlo Automation, a veteran-owned supplier of surplus industrial parts, carries the Siemens 1FT6041-4AF71-4EG1. We provide reliable components and efficient service to help you maintain your production capabilities with minimal interruption.

Frequently asked questions

What is the purpose of the 10% derating on the 1FT6041-4AF71-4EG1?

The 10% derating on the Siemens 1FT6041-4AF71-4EG1 is due to the inclusion of an absolute EnDat encoder. Absolute encoders require additional power and generate heat, so this derating ensures the motor operates reliably within its thermal limits.
