Siemens 1FK7042-2AK71-1CG1 Permanent Magnet Synchronous Motor

Siemens SIMOTICS S 1FK7042-2AK71-1CG1 is a compact permanent-magnet synchronous servo motor from the 1FK7 family. It is rated at 0.94 kW with a continuous torque of 3 Nm (100%) and a nominal speed of 6000 rpm (NN), delivered by a naturally cooled IMB5 design (IM V1, IM V3) with flange 1 mounting. The drive is configured for a 600 V DC bus (UDC) and promises robust performance in demanding automation environments, featuring an IP65 enclosure for protection against dust and water jets. A rotatable power connector provides installation flexibility, while the integrated encoder AM24DQI offers a 24-bit absolute position value with a 12-bit multi-turn, all accessible through a DRIVE-CLiQ interface for streamlined feedback connectivity. The encoder is paired with a 2-pole resolver to support reliable reference and commutation data for precise motor control. This 1FK7 variant is engineered for high-precision, dynamic motion tasks in automation and machine-tool applications where compact size, precise feedback, and rugged protection are essential.
