Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1113-6WU11-1BA0 is a SIMOTICS M 1FE1 built-in synchronous motor designed for high-performance, high-torque spindle and machine-tool applications. It is a 6-pole permanent-magnet synchronous motor with a 600 V DC-link voltage, 105 K thermal rating, IP00 protection, and water cooling. The motor provides 33 kW rated output power, 150 Nm rated torque, and 60 A rated current at a rated speed of 2100 RPM. Its maximum speed is 6500 RPM, making it suitable for demanding industrial spindle applications. The motor uses KTY temperature sensing and an overhead-encapsulated winding with standard protection for reliable thermal monitoring. It is supplied with a standard cooling jacket, without a rotor sleeve, and has 0.5 m free cable ends with a rigid connection. A Voltage Protection Module (VPM) is required for this configuration. The motor consists of separate rotor and stator components, allowing integration into specialized spindle assemblies. It is suitable for CNC machine tools, heavy-duty spindles, precision machining, and industrial automation requiring high torque, controlled cooling, and reliable continuous operation.
