Siemens SIMOTICS M 1FE1 Built-In Synchronous Moto About

The Siemens 1FE1084-6WX11-8BW3 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 with a 600 V DC-link voltage, water cooling, and IP00 protection as an integrated component. The stator configuration is rated at 15 kW output power, 130 Nm torque, and 30 A rated current at a rated speed of 1100 RPM. The maximum permissible speed is 4500 RPM. It uses overhead-encapsulated winding with standard protection and incorporates two Pt1000 temperature sensors for thermal monitoring. The configuration includes a standard cooling jacket and 0.5 m bare cable ends located at the small outer diameter. This is a stator-only spare part, intended to be combined with the corresponding rotor to form a complete built-in synchronous motor. Siemens lists the net weight at approximately 22 kg. The motor is suitable for CNC machine tools, precision spindles, machining equipment, and industrial automation requiring compact construction, controlled cooling, and reliable continuous operation.
