Product description

The Siemens 1FK7022-5AK71-1LB0 is a SIMOTICS S Synchronous servo motor from the 1FK7 Compact series, featuring a holding brake for secure positioning. It delivers 0.85Nm of torque at 6000rpm with a 0.38kW power rating, using natural cooling. This model includes rotatable 270° power/signal connectors, IMB 5 design (IM V1, IM V3), Flange 1, and a 20-bit +12-bit multi-turn absolute encoder with a Drive-CLiQ interface (AM20DQ). It has a shaft with a fitted key (tolerance N), a holding brake, and IP64 protection. A 10% derating applies due to the absolute encoder.

This servo motor is ideal for applications requiring accurate positioning and holding capability, such as vertical axes on robots, automated storage and retrieval systems (AS/RS), and machine tool indexing tables. The integrated holding brake ensures the load is maintained in position when power is removed or during system shutdowns.

Frequently asked questions

What is the role of the holding brake in the 1FK7022-5AK71-1LB0 servo motor?

The holding brake in the Siemens 1FK7022-5AK71-1LB0 is designed to safely hold the motor shaft in position when power is off, preventing accidental movement of the load. It engages automatically when the drive power is removed.
