1FK7042-2AK71-1RH0-ZN24 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RH0-ZN24 is a high-precision synchronous motor engineered for advanced automation and motion-control applications. Delivering a nominal power of 0.94 kW and a torque of 3 Nm at 6000 rpm, it combines compact design with outstanding energy efficiency. Featuring natural cooling, a rotatable power connector, and an IP64 protection rating, this motor ensures robust performance and reliability even in demanding industrial conditions. The reinforced 8 Nm holding brake and multi-turn 20-bit absolute encoder (AM20DQI) provide enhanced safety and superior position accuracy, enabling smooth control in complex machine systems.

This SIMOTICS S series motor is part of the well-known SIEMENS 1FK7 family — trusted worldwide for precision, responsiveness, and long-term durability. Its permanently excited synchronous technology ensures consistent torque delivery, low vibration, and quiet operation. Thanks to the integrated Pt1000 temperature sensor, thermal monitoring is precise, preventing overheating and extending the service life of connected components. The plain shaft with tolerance N guarantees easy coupling and minimal maintenance throughout continuous operation.

Overview

SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous motors built for versatility and precision. They can be combined seamlessly with SINAMICS S120 or S220 drive systems to create a powerful, highly dynamic motion solution. The motor design eliminates the need for external cooling systems, as heat is dissipated efficiently through the housing surface. With high overload capability and exceptional torque linearity, the SIMOTICS S-1FK7 series ensures stable performance under variable load conditions.

• Space-saving construction with excellent power density
• Suitable for diverse applications including packaging, robotics, and textile machines
• High-dynamic or high-inertia configurations available
• Reliable control response with minimal commissioning effort

Applications

Typical uses include machine tools, robotics and handling systems, wood and glass processing, packaging machinery, and printing applications. Its versatility and durability make it ideal for industries requiring precision motion, fast positioning, and consistent torque delivery in compact installations.
