1FK7042-2AF71-1CG1-ZJ29 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor 1FK7042-2AF71-1CG1-ZJ29 is a premium compact synchronous servo motor engineered for precise motion control and long-term performance in advanced automation systems. With a rated power of 0.82 kW and a torque of 3 Nm (100 K), this high-efficiency design supports a nominal speed of 3000 rpm at 600 V DC. It operates with natural cooling and offers a plain shaft with standard N tolerance, ensuring smooth, stable rotation and low maintenance in continuous operation.

Equipped with an absolute encoder AM24DQI featuring 24-bit + 12-bit multiturn resolution and a DRIVE-CLiQ interface, the motor guarantees accurate feedback and seamless integration with SINAMICS drive systems. The unit’s construction follows the IMB 5 (also IM V1, IM V3) mounting standard and includes a rotatable power connector for flexible cable management in space-constrained control cabinets. The entire system achieves IP65 protection, offering superior resistance to dust and moisture in demanding industrial environments.

Overview

The SIMOTICS S-1FK7 series represents the next generation of permanent-magnet synchronous motors from SIEMENS, combining compact dimensions with outstanding power density. These motors can be paired with the SINAMICS S120 or S220 drive platforms to create dynamic, modular systems for a wide range of applications. Thanks to their integrated encoder options, the motors offer precise speed and position control for high-performance machinery.

Designed for operation without external fans, the heat is efficiently dissipated through the housing surface. This structure reduces component complexity and enhances system reliability. With a high overload capacity and excellent thermal behavior, the SIMOTICS S-1FK7 motors provide consistent output even under fluctuating loads. The series covers Compact, High Dynamic, and High Inertia variants — allowing users to select the perfect match for either lightweight precision tasks or heavy duty motion sequences.

Benefits and Applications

Key advantages include compact installation with high power density, robust closed-loop control, and exceptional dynamic response. The motor is ideal for machine tools, robots, handling systems, packaging, printing, wood, ceramic, and plastic processing equipment. Its integrated planetary gearing (ALPHA SP+ SP 075S-MF1, 1-stage, ratio 10) further enhances torque transmission and precision motion. Every unit is built to ensure efficiency, accuracy, and durability for industrial automation demands.
