1FK7042-3BK71-1RG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New
The SIEMENS SIMOTICS S 1FK7042-3BK71-1RG1 is a high-performance synchronous servo motor engineered for precision, reliability, and energy efficiency. Delivering 0.94 kW rated power and operating at 6000 rpm, this compact motor provides 3 Nm rated torque with natural cooling and a rugged IP65 protection rating. Its design supports a wide range of automation applications where accuracy, durability, and control responsiveness are essential. The motor features a smooth shaft with tolerance class N, a rotatable power connector, and an integrated AM20DQI 20-bit + 12-bit multi-turn encoder with DRIVE-CLiQ interface for precise motion control. With its robust design and high dynamic response, this motor offers excellent stability even in demanding industrial environments.
Overview
The SIMOTICS S-1FK7 motor series represents the next generation of permanent-magnet synchronous motors, developed to meet the growing needs of modern automation systems. Compact yet powerful, these motors can be seamlessly combined with SINAMICS S120 or S220 drives to form a fully integrated drive system that delivers exceptional accuracy and flexibility. Thanks to its innovative cooling concept, the heat generated is dissipated through the surface of the motor, allowing it to operate efficiently without external cooling. The motor’s compact structure and superior torque density make it ideal for space-constrained machinery while maintaining stable performance during continuous operation.
Design and Benefits
The 1FK7042-3BK71-1RG1 offers remarkable mechanical and control advantages. Its high inertia rotor design ensures smooth operation and minimal vibration, making it suitable for systems with variable load moments. The integrated encoder provides precise position feedback, while the naturally cooled structure ensures long service life and reduced maintenance. Key benefits include:
- Space-efficient installation with exceptional power-to-size ratio
- Reliable closed-loop control with fast dynamic response
- Flexible integration with SINAMICS drive systems
- Ideal for machine tools, robotics, packaging, and printing applications
- Low commissioning effort and high operational stability
