Product description

The Siemens 1FK7042-2AF71-1RG2 is a SIMOTICS S-1FK7-CT synchronous motor, providing 0.82 kW of rated power and 3 Nm of torque at 100K. It operates at 3000 rpm with natural cooling, utilizing an MB 5 flange (IM V1, IM V3) and power connector. This model features an AM20DQI absolute encoder with a DRIVE-CLiQ interface, a plain shaft (tolerance N) without a holding brake, and boasts an IP65 protection rating for the motor and IP67 for the DE flange.

This motor is designed for demanding applications requiring high precision and superior environmental protection. The IP65/IP67 rating ensures robust defense against dust and high-pressure water jets, making it suitable for washdown environments or areas with significant ingress risk. Its applications are broad, from robotics to specialized machine tools.
