Siemens 1FK7-HI Synchronous Motor — 2.7 kW, 3000 RPM, IP65
Siemens 1FK7-HI Series Synchronous Motor
The Siemens 1FK7081-3BF71-1CG1 is a high-performance SIMOTICS S synchronous motor from the 1FK7-HI (High Inertia) series. It delivers 2.7 kW of rated power at 3000 rpm, operating at a 600V DC link voltage and producing 12 Nm of nominal torque (at 100K). This naturally cooled motor features IMB 5 (IM V1, IM V3) mounting with flange 1 and a rotatable power connector. It is equipped with a 24-bit + 12-bit multiturn absolute encoder (encoder AM24DQI) with a DRIVE-CLiQ interface, a smooth shaft with tolerance N, and boasts an IP65 degree of protection. This model does not include a holding brake.
This motor is designed for demanding automation tasks requiring precise positioning and high dynamics, especially in applications with higher inertia loads. Suitable for advanced machine tools, complex robotics, and high-speed packaging equipment where continuous precise motion is critical.
