The 1FK7063-2AF71-1RH1 belongs to Siemens’ SIMOTICS S-1FK7 Compact family of permanent-magnet synchronous servo motors, optimized for high-performance servo applications with SINAMICS S120 drives. Rated at 2.3 kW with 5.1 Nm continuous torque (11 Nm stall torque) at 3000 rpm, it delivers excellent dynamic response for axes requiring precise positioning and rapid acceleration in machine tools, robotics, and handling systems. The motor operates on 3-phase AC power (typically 400 V class) with 5.6 A rated current and supports high overloads for short-term peaks.
This compact model features a self-cooled design (surface cooling), IP64/IP65 protection (depending on shaft seal), and an integrated encoder (typically 22-bit absolute or incremental Hiperface/EnDat) for high-resolution feedback. The frame size 7 construction provides high torque density in a small footprint, with natural cooling enabling operation up to 40-60°C ambient. It’s suited for multi-axis systems with DC bus sharing and offers low rotor inertia for responsive motion control.
Units are available new, refurbished, or exchange for maintenance of Siemens motion systems.
