Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1091-6WN30-1BC0 is a SIMOTICS M 1FE1 built-in synchronous motor designed for high-speed precision spindle and machine-tool applications. It is a 6-pole permanent-magnet synchronous motor designed for a 600 V DC-link voltage, with water cooling and IP00 protection as an integrated motor component. The 1FE1091 family is available in configurations with approximately 10 kW rated output power, 28 Nm rated torque, and 24 A rated current at a rated speed of 3500 RPM, with a maximum speed of 7000 RPM. Siemens listings identify the 1FE1091 family as using overhang-encapsulated winding with standard KTY thermal protection, a standard cooling jacket, and rotor-sleeve configurations. The exact -6WN30-1BC0 suffix is a specific configuration, so option-dependent details such as rotor sleeve, cable arrangement, and component configuration should be verified against the Siemens MLFB documentation before procurement. It is suitable for CNC spindles, precision machining, grinding, and other industrial applications requiring compact construction, high rotational speed, and reliable thermal management.
