Description
Product Description
The Siemens 1FT7102-5AB71-1BA4 is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial motion control applications requiring high precision, exceptional dynamic response, and long-term reliability. Optimized for operation with Siemens SINAMICS S120 drive systems, this motor is ideal for CNC machine tools, robotics, packaging equipment, material handling systems, and automated production lines.
Delivering an optimum output power of 4.1 kW at a rated speed of 1,500 RPM, the motor provides a rated torque of 26 Nm and a stall torque of 30 Nm (100 K). Its natural cooling design eliminates the need for external cooling equipment while ensuring efficient continuous-duty operation. The permanent magnet rotor offers excellent torque density, rapid acceleration, and highly accurate positioning.
The 1FT7102-5AB71-1BA4 features an IM B5 flange mounting, IP65 protection, a plain shaft, integrated Pt1000 temperature monitoring, and a high-resolution encoder for precise position and speed feedback. A turnable SPEED-CONNECT power connector simplifies installation and maintenance, making the motor a dependable solution for high-performance automation systems. Configuration-specific encoder and connector options are defined by the complete Siemens MLFB code.
