Siemens 1FK7042-2AF71-1EB2 SIMOTICS S Motor (Absolute Encoder, KTY)
Siemens 1FK7-CT synchronous motor with absolute encoder, KTY sensor, and IP67 DE flange.
The Siemens 1FK7042-2AF71-1EB2 is a SIMOTICS S synchronous motor from the 1FK7-CT series, delivering 0.82 kW of power at 600 V DC. It provides 3 Nm of torque at 100K and a nominal speed of 3000 rpm, with natural cooling. This naturally cooled motor is designed for IMB 5 (IM V1, IM V3) mounting with flange 1. It features a rotatable power connector, a KTY temperature sensor, and an absolute encoder (AM2048S/R) with ENDAT interface, offering 2048 S/R + 4096 multiturn resolutions. The shaft is fitted with a key, tolerance N, and includes a holding brake, with an IP65 degree of protection for the motor body and IP67 for the DE flange.
This motor is engineered for applications demanding high precision, dynamic performance, and integrated temperature monitoring. Common uses include advanced robotics, high-speed automation, and CNC machinery where accurate positional feedback and thermal management are critical. The combination of the ENDAT absolute encoder and the KTY sensor ensures reliable data for complex control loops.
