1FK7042-3BK71-1RH1-ZJ13 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New
The SIEMENS 1FK7042-3BK71-1RH1-ZJ13 belongs to the SIMOTICS S-1FK7 family of synchronous motors, engineered for precision, performance, and long-term durability in demanding industrial environments. This exclusive high-inertia model is rated at 0.94 kW nominal power with a torque of 3 Nm and operates at 6000 rpm. Its naturally cooled design with IMB 5 (IM V1, IM V3) mounting ensures stable operation and low maintenance. Equipped with an absolute encoder 20-bit + 12-bit multi-turn via DRIVE-CLiQ interface (AM20DQI) and a smooth shaft featuring an integrated holding brake, this motor delivers precise position control and optimal synchronization.
This unit also includes the ALPHA SP+ SP 075S-MF2 planetary gearbox, a two-stage configuration with a 20:1 gear ratio and feather key connection, designed for enhanced torque transfer and mechanical stability. Its IP65 degree of protection safeguards the unit against dust and moisture, ensuring reliable operation even in harsh conditions. Together, these features make the 1FK7042-3BK71-1RH1-ZJ13 a robust solution for precision motion and high-performance automation.
Overview
The SIMOTICS S-1FK7 series represents Siemens’ advanced generation of permanent-magnet synchronous motors. Each model is designed for integration with SINAMICS S120 and S220 drive systems, enabling a fully coordinated motion control setup. These motors are compact, efficient, and can be configured with various encoders and gearboxes to match specific industrial needs. Heat dissipation occurs naturally through the surface, eliminating the need for external cooling systems. The 1FK7042-3BK71-1RH1-ZJ13 maintains high overload capacity, allowing smooth performance even under fluctuating load conditions.
