1FK7042-3BK74-1AA0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-3BK74-1AA0 is an advanced high-inertia synchronous motor designed for precision motion control in demanding industrial environments. Delivering a nominal power of 0.94 kW at 600 V DC with a rated torque of 3 Nm and a maximum speed of 6000 rpm, this model combines exceptional performance with superior build quality. The motor features a naturally cooled construction, IMB5 flange design, and a rotatable power connector for flexible installation. Its incremental encoder (IC2048S/R) with 2048 signal lines and sin/cos 1 Vpp output ensures high-resolution feedback and precise speed control. Built with a rugged IP64 protection class, the SIMOTICS S motor is engineered for long-term reliability and high operational stability in challenging industrial environments.

Overview

The SIMOTICS S-1FK7 motor series from Siemens is a premium range of compact, permanent-magnet synchronous motors developed for maximum flexibility and efficiency. The 1FK7042-3BK74-1AA0 variant belongs to the High Inertia (HI) line, offering excellent closed-loop control properties ideal for variable load conditions. When combined with the SINAMICS S120 or S220 drive systems, the SIMOTICS S motors deliver exceptional dynamic performance, high accuracy, and reliable operation. The integrated encoder systems provide precise position and speed control, adapting seamlessly to complex motion profiles in automation systems. Designed for maintenance-free operation, the motor dissipates heat naturally through its surface, eliminating the need for external cooling systems.
