CAN BE ROTATED BY 270 DEGR., ABSOLUTE ENCODER ENDAT 2048 P/REV (ENCODER A-2048); PERFORMANCE REDUCTION BY 10% DUE TO ABSOLUTE ENCODER; PLAIN SHAFT, TOLERANCE N; W/O HOLDING BRAKE DEGREE OF PROTECTION IP64; PAINT FINISH RAL7016 N16: NICKEL PLATED PLUG
Performance and Design
The 1FK7 Compact motor features a plain shaft with tolerance class N, ensuring smooth, vibration-free rotation. It uses an absolute encoder EnDat 2048 P/rev (Encoder A-2048), which provides exact position feedback for advanced motion control.
Although performance reduces by 10% due to the absolute encoder, its overall efficiency remains outstanding for most industrial setups. The IM B5 (IM V1, IM V3) mounting configuration offers installation flexibility across various machine orientations.
Durability and Build Quality
Constructed with a degree of protection IP64, the 1FK7105-5AC71-1EG3-Z motor is resistant to dust ingress and water splashes, ensuring long operational life. The nickel-plated plug provides superior corrosion resistance, while the RAL7016 paint finish enhances surface durability and protection from harsh conditions.
Furthermore, its power and signal connectors can rotate up to 270 degrees, simplifying cable management and allowing easy integration into compact mechanical systems.
Reliability and Applications
Because it uses natural air cooling, the motor operates efficiently without complex external cooling systems. This design reduces maintenance and ensures dependable long-term performance. The 48 Nm torque output supports high-precision, high-speed applications requiring constant torque delivery and excellent acceleration characteristics.
Commonly used in servo-driven machinery, conveyor automation, and manufacturing systems, this Siemens motor combines precision, adaptability, and robust engineering to keep production lines moving efficiently.
Summary
The Siemens 1FK7105-5AC71-1EG3-Z SIMOTICS S Synchronous Servomotor offers exceptional torque density, precision feedback, and durable construction. With flexible installation options, IP64 protection, and easy connector rotation, it remains a trusted solution for advanced industrial motion applications.
