1FK7042-2AK74-1SB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor 1FK7042-2AK74-1SB1 represents an advanced generation of compact permanent-magnet motors built for high-precision motion control and industrial automation. Delivering a nominal power of 0.94 kW and a rated torque of 3 Nm at 6000 rpm, this unit provides reliable performance in dynamic applications. Its naturally cooled IMB 5 flange design with IP65 protection ensures durability and long-term stability even under demanding production conditions.

Equipped with a rotatable multi-pole power connector, a resolver P = 4, and a Pt1000 temperature sensor, this model guarantees accurate temperature monitoring and flexible installation. The precision shaft with feather key and holding brake enables secure torque transmission and precise positioning. This motor is optimized for integration within automated environments where space efficiency, repeatability, and energy efficiency are essential.

Overview

The SIMOTICS S-1FK7 series is recognized for its modular design and broad compatibility with SINAMICS S120 and S220 drive systems. Each unit can be adapted through different encoder and gearbox configurations to suit varied industrial applications. The natural cooling design eliminates the need for external fans, while its high overload capability allows consistent torque delivery across a wide load range. The system achieves smooth operation and long service life with minimal maintenance requirements.
