Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1091-6WS30-8BW2 is a SIMOTICS M 1FE1 built-in synchronous motor spare part, stator only, designed for high-speed precision spindle and machine-tool applications. It is a 6-pole permanent-magnet synchronous motor stator designed for a 600 V DC-link voltage, 105 K thermal rating, IP00 protection, and water cooling. The stator configuration provides 6.3 kW rated output power, 30 Nm rated torque, and 15 A rated current at a rated speed of 2,000 RPM. Its maximum permissible speed is 4,000 RPM. The stator uses overhead encapsulation with full protection and incorporates two temperature sensors with Pt1000 for reliable thermal monitoring. It is supplied with a standard cooling jacket and 0.5 m bare cable ends. As a stator-only spare component, it is intended to be combined with the matching rotor and cooling arrangement to form a complete built-in synchronous motor. The configuration is suitable for CNC spindles, precision machining, grinding equipment, machine tools, and industrial automation requiring compact construction, water cooling, reliable thermal monitoring, and controlled high-speed operation. The exact specifications are confirmed by the Siemens Industry Mall datasheet.
