Product description

The Siemens 1FK7105-5AC71-3AA3 is a SIMOTICS S-1FK7 synchronous servo motor from the 1FK7 Compact series. It operates at a nominal speed (NN) of 2000 rpm with a DC link voltage (UDC) of 600 V. The motor is designed with an IMB5 configuration, featuring a power connector fixed towards the NDE (Non-Drive End). It includes an incremental encoder (sin/cos 1VSS 2048 S/R). The shaft is plain with a feather key and tolerance N, and it does not have a holding brake. The degree of protection is IP64, and it is finished in RAL 7016 (anthracite). This is a customer-specific version motor.

This servo motor is suitable for a wide range of industrial automation applications, including machine tools, robotics, and packaging machinery, where precise speed control and positioning are critical. Its IMB5 mounting and specific encoder type make it adaptable to various system designs.
