Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1124-4WQ01-1AA8 is a SIMOTICS M 1FE1 built-in synchronous motor designed for high-performance spindle and precision machine-tool applications. It is a 4-pole permanent-magnet synchronous motor with a 600 V DC-link voltage, 105 K thermal rating, IP00 protection, and water cooling. The motor provides 48.7 kW rated output power, 155 Nm rated torque, and 90 A rated current at a rated speed of 3000 RPM. Its maximum permissible speed is 12,000 RPM, making it suitable for high-speed CNC spindle and precision machining applications. The configuration consists of individual rotor and stator components and requires a Voltage Protection Module (VPM) for operation at the specified high speeds. The motor is designed for integration into a complete spindle assembly rather than conventional standalone motor mounting. Its robust water-cooled construction provides effective thermal management during continuous industrial operation. The listed net weight is approximately 63 kg. This motor is suitable for CNC machine tools, high-speed spindles, precision machining centers, grinding equipment, and other demanding industrial applications requiring high torque, high power density, accurate speed control, and reliable thermal performance.
