8.2kW Power 3000rpm Speed 48Nm Torque Multi-pole Resolver Feedback Holding Brake IP64 Protection

The Siemens SIMOTICS S Synchronous Motor 1FK7105-2AF71-1UH0 is designed for high-performance automation tasks, featuring a multi-pole resolver for feedback. This motor has a nominal power of 8.2 kW and a nominal speed of 3000 rpm, with a torque of 48 Nm. It is naturally cooled and built to IMB 5 design standards (IM V1, IM V3), featuring a flange 1 mount and a rotatable power connector. This model includes a smooth shaft (tolerance N), an integrated holding brake, and an IP64 degree of protection. Instead of an absolute encoder, it uses a multi-pole resolver with a Drive-CLiQ interface for position feedback.

This motor is suitable for applications requiring precise speed and position control, especially where a resolver offers advantages over absolute encoders. It is commonly applied in machine tools, robotics, and general industrial automation where robust feedback is essential. Industries that benefit include manufacturing, automation, and specialized machinery construction.

Siemens SIMOTICS S 1FK7-CT 1FK7 Servo Motor Resolver Siemens 1FK7 Motor
This motor is part of the Siemens SIMOTICS S 1FK7 series and uses a multi-pole resolver for feedback. It can replace older Siemens motors or other drive systems where resolver feedback is preferred or required.
Expert tip
Resolver-based feedback requires a compatible resolver interface on the motor controller or drive; ensure correct wiring for accurate position sensing.

What is the difference between the encoder and resolver feedback on Siemens 1FK7 motors?
The 1FK7105-2AF71-1UH0 uses a multi-pole resolver, which is robust and effective for speed and position feedback. Other 1FK7 motors in this series may use absolute encoders, which provide absolute position data upon startup without needing a reference run.
