Product description

The Siemens 1FT6041-4AF71-4EH1 is a SIMOTICS S synchronous servo motor equipped with a holding brake, designed for critical automation applications. It features natural cooling, an IM B5 mounting configuration, and a rated torque of 2.5 Nm at 100K. This motor includes an Absolute encoder (EnDat 2048 S/R) for precise positioning, leading to a 10% derating. It has a smooth shaft with circular runout tolerance N, a vibration severity grade of N, and Gamma sealing for IP65 protection.

This servo motor is ideal for applications requiring holding torque when stationary or for added safety in vertical axis movements, such as in robotics, vertical conveyors, and machine tools. The IP65 rating ensures protection against dust and water jets.

Frequently asked questions

What is the function of the holding brake in the Siemens 1FT6041-4AF71-4EH1?

The holding brake in the Siemens 1FT6041-4AF71-4EH1 provides a static holding torque when the motor is de-energized. This is crucial for applications where the load needs to be held in position, such as on vertical axes or to prevent movement during power loss.
