Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1116-6WT31-8BW0 is a SIMOTICS M 1FE1 built-in synchronous motor, stator-only component, designed for high-torque, high-precision spindle and machine-tool applications. It is a 6-pole permanent-magnet synchronous motor designed for a 600 V DC link, with water cooling and IP00 protection. The configuration provides 28 kW rated output power, 300 Nm rated torque, and 84 A rated current at a rated speed of 900 RPM. Its maximum permissible speed is 5,500 RPM. The stator uses overhang-encapsulated winding with full protection, including two temperature sensors and PTC protection, plus a Pt1000 temperature sensor. A Voltage Protection Module (VPM) is required for this configuration. It is supplied with a standard cooling jacket and 1.5 m bare cable ends located at the larger outside diameter. The exact Siemens Industry Mall listing specifies a net weight of approximately 73 kg. This stator-only component is intended to be combined with the corresponding rotor and is suitable for heavy-duty CNC spindles, machine tools, precision machining, and industrial applications requiring high torque and reliable thermal management.
