1FK7033-4CF21-1QB0 SIEMENS Exclusive SIMOTICS S-1FK7 High Dynamic Synchronous Motor Original Brand New

The SIEMENS 1FK7033-4CF21-1QB0 is a premium synchronous motor from the SIMOTICS S-1FK7 High Dynamic series, engineered to deliver precision, performance, and dependability in automation environments. Designed for compact installations, this permanent-magnet motor achieves a nominal power of 0.38 kW and a torque of 1.3 Nm at 3000 rpm. Its naturally cooled IMB 5 construction ensures efficient thermal management through the motor’s outer surface, providing steady operation without external cooling components. The robust IP64 protection rating makes it suitable for a wide range of industrial environments where dust and moisture resistance are essential.

Featuring a 20-bit single-turn absolute encoder with DRIVE-CLiQ interface, the motor guarantees precise feedback for high-accuracy position and speed control. It includes a fitted-key shaft with tolerance N and an integrated holding brake, ensuring smooth and secure performance. The rotatable power connector simplifies wiring and installation, even in space-constrained machine designs. When combined with the SINAMICS S120 or S220 drive systems, the motor becomes part of a powerful, flexible solution that supports advanced motion control applications.
