Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1143-8WQ31-8BW2 is a SIMOTICS M built-in synchronous motor individual stator component designed for high-performance spindle and precision machine-tool applications. It operates with a 600 V DC-link voltage, uses water cooling, and has IP00 protection as an integrated motor component. According to the Siemens Industry Mall, this configuration provides 61.3 kW rated output power, 325 Nm rated torque, and a rated speed of 1,800 RPM. The maximum permissible speed is 8,000 RPM. The stator uses water-cooled overhead encapsulation with full protection and incorporates two Pt1000 temperature sensors for reliable thermal monitoring. It is supplied with a standard cooling jacket and 0.5 m bare cable ends. The listed net weight is approximately 68 kg. As an individual stator component, it is intended to be integrated with the matching rotor to form a complete built-in synchronous motor. The motor is suitable for high-torque CNC spindles, heavy-duty machine tools, precision machining, and industrial applications requiring high power density and effective water cooling.
