The Siemens 1FK7032-5AK71-1UA0 is a SIMOTICS S-1FK7 compact permanent-magnet synchronous servo motor designed for precise motion control in industrial automation systems. It offers a rated speed of 6000 rpm, 0.5 kW optimum power, 0.8 Nm rated torque, and 1.10 Nm static torque at 100 K, making it suitable for dynamic positioning and drive applications where compact size and reliable performance are required.
This motor features natural cooling, IP64 protection, IM B5 mounting with IM V1 and IM V3 compatibility, and rotatable power and signal connectors for flexible installation. It is equipped with a resolver R15DQ encoder system with 15-bit resolution, a KTY84 temperature sensor in the stator, and a feather key shaft end. The unit is supplied without a holding brake and has a net motor weight of approximately 2.7 kg.
With a maximum mechanical speed of 10000 rpm and a maximum inverter speed of 12800 rpm, the 1FK7032-5AK71-1UA0 is well suited for use in machinery requiring accurate speed regulation, efficient servo control, and consistent torque output in a compact Siemens motor format.
