Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor Rotor About

The Siemens 1FE1062-6WQ31-5WD2 is a SIMOTICS M 1FE1 built-in synchronous motor individual rotor component, designed for high-speed precision spindle and machine-tool applications. It is a 6-pole permanent-magnet synchronous motor rotor designed for a 600 V DC-link voltage and water cooling. The corresponding motor configuration provides approximately 14 kW rated output power, 23 Nm rated torque, and 28.5 A rated current at a rated speed of 5,800 RPM. The maximum permissible speed is 12,000 RPM, making it suitable for demanding high-speed spindle applications. The configuration uses overhead-encapsulated winding with full protection, including two temperature sensors and PTC protection, for reliable thermal monitoring. The rotor is supplied as an individual component, intended to be integrated with the matching stator and cooling arrangement rather than used as a standalone motor. A Voltage Protection Module (VPM) is required for this configuration. It is suitable for CNC machine tools, high-speed spindles, precision machining, grinding, and other industrial applications requiring high rotational speed, compact construction, and reliable thermal performance. Siemens product listings identify this exact model as a rotor component.
