1FK7042-3BK71-1RH1-ZJ29 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-3BK71-1RH1-ZJ29 is a precision-engineered synchronous motor designed for high-performance motion control in advanced automation systems. With a rated power of 0.94 kW and a speed of up to 6000 rpm, this compact servo motor delivers exceptional torque and energy efficiency. Featuring a naturally cooled IMB5 design and a rotatable power connector, it ensures simple installation and reliable operation in diverse industrial environments. The motor includes a 20-bit absolute encoder with 12-bit multi-turn capability and DRIVE-CLiQ interface, allowing for accurate feedback and integration into SINAMICS drive systems. The unit also features a smooth shaft, holding brake, and an IP65 protection rating for robust, maintenance-free operation.

Overview

The SIMOTICS S-1FK7 series is part of Siemens’ next-generation portfolio of permanent-magnet synchronous motors designed for precision motion, reliability, and compactness. These motors combine compact dimensions with high torque density, making them ideal for applications requiring precise speed and position control. The series can be seamlessly combined with SINAMICS S120 or S220 drive systems to create a powerful, flexible, and highly efficient automation solution. Depending on configuration, the integrated encoders enable advanced position feedback for highly dynamic applications such as robotics and precision machining. Designed for operation without external cooling, heat is dissipated directly through the housing surface, ensuring stable thermal performance and extended service life.

Benefits

• Compact construction for space-saving installations and versatile mounting options.
• High dynamic response with very low rotor inertia for precision movements.
• Excellent control stability for high or varying load inertia conditions.
• Reliable, maintenance-free operation with IP65 protection level.
• Seamless integration with Siemens drive systems via DRIVE-CLiQ interface.
• Suitable for demanding applications requiring both accuracy and durability.

Applications

The SIMOTICS S-1FK7 motors are widely used in modern automation sectors including machine tools, robotics, packaging, plastics, printing, and material processing equipment. Their combination of torque precision, durability, and adaptability ensures consistent performance in high-speed and high-load environments. The integration of the ALPHA SP+ SP 075S-MF1 planetary gearbox (i=10) further enhances torque delivery, optimizing performance for motion-intensive systems and precision positioning operations.
