Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1042-6WN30-1BA0 is a SIMOTICS M 1FE1 built-in synchronous motor designed for high-speed, high-precision 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 1FE1042 family is designed for high-speed operation, with configurations offering approximately 14.4 kW rated output power, 11 Nm rated torque, and a rated speed of up to 12,500 RPM, depending on the exact winding configuration. The motor uses an overhang-encapsulated winding with standard KTY thermal protection and a standard cooling jacket. The -WN30-1BA0 configuration belongs to the individual-component SIMOTICS M range and is intended for integration of the matching stator and rotor rather than conventional standalone mounting. It is suitable for CNC high-speed spindles, precision machining, grinding equipment, and other industrial applications requiring compact construction, high rotational speed, reliable thermal monitoring, and efficient water cooling. Siemens product listings confirm the 1FE1042 family as a SIMOTICS M built-in synchronous motor range.
