1FK7033-4CF21-1RA1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS 1FK7033-4CF21-1RA1 SIMOTICS S-1FK7 is a premium-quality synchronous motor designed to deliver precise, reliable performance in modern automation systems. Built with advanced engineering, this high-dynamic model combines compact dimensions with impressive torque density, enabling seamless integration into a wide range of industrial machinery. With a nominal power rating of 0.38 kW, a torque of 1.3 Nm, and a rated speed of 3000 rpm, it ensures exceptional stability and efficiency under demanding conditions. The naturally cooled design dissipates heat efficiently through the motor housing, ensuring consistent thermal management without requiring external cooling devices.

This motor is equipped with an integrated 20-bit absolute encoder combined with a 12-bit multi-turn system, utilizing the DRIVE-CLiQ interface for precise communication and feedback. The rotatable power connector allows flexible mounting configurations, while the IP65 degree of protection provides durability against dust and moisture. Its shaft with fitted key and tolerance class N ensures mechanical precision and secure coupling in high-performance setups. The absence of a holding brake simplifies installation for applications that require free shaft movement.
