Description
Product Description
The Siemens 1FT7102-5AB71-1BE3 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-precision motion control and demanding industrial automation applications. Engineered for seamless compatibility with Siemens SINAMICS S120 servo drive systems, it delivers exceptional positioning accuracy, high torque density, rapid acceleration, and reliable continuous-duty operation. This servo motor is ideally suited for CNC machining centers, robotics, packaging machinery, material handling systems, printing equipment, textile machinery, and automated production lines.
With a rated output power of 4.1 kW at 1,500 RPM, the motor delivers 26 Nm rated torque, 30 Nm stall torque (100 K), and 120 Nm maximum torque. Its permanent magnet synchronous design ensures high efficiency, low rotor inertia, smooth operation, and excellent dynamic response, making it suitable for demanding servo applications requiring precise speed and position control.
The 1FT7102-5AB71-1BE3 features natural cooling, IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature monitoring, and a high-resolution encoder for accurate motion feedback. The 1BE3 suffix denotes a specific encoder and connection configuration within the SIMOTICS S-1FT7 family while maintaining the same core mechanical and electrical performance. Encoder interface details are defined by the complete Siemens MLFB ordering code.
