SIMOTICS S Series Synchronous Servo Motor 2.5 Nm Torque 6000 rpm Speed EnDat Absolute Encoder Integrated Holding Brake

Product description

The Siemens 1FT6041-4AK71-4EH0 is a SIMOTICS S synchronous servo motor engineered for precise motion control, featuring 2.5 Nm of torque and capable of reaching 6000 rpm. It operates with natural cooling and has an IM B5 flange mounting. This motor includes an EnDat 2048 S/R absolute encoder, necessitating a 10% derating. It is characterized by a smooth shaft, circular runout tolerance N, a labyrinth seal for IP64 protection, and importantly, a built-in holding brake for secure positioning.

This servo motor is well-suited for applications requiring high accuracy and reliable holding capabilities, such as vertical axis positioning in robotics, automated assembly lines, and machine tools. Industries benefiting from this motor include medical device manufacturing, semiconductor production, and high-precision industrial automation.
