Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1052-4HD10-6BA0 is a SIMOTICS M 1FE1 four-pole built-in synchronous motor designed for high-speed precision spindle and machine-tool applications. It operates with a 600 V DC-link voltage and is intended for high-speed operation with a series reactor for safe operation. The motor provides 31.4 kW rated output power, 12 Nm rated torque, and 57 A rated current at a rated speed of 25,000 RPM. Its maximum permissible speed is 40,000 RPM, making it suitable for ultra-high-speed CNC spindles, precision machining, grinding, and other demanding industrial applications. The rotor has an inertia of approximately 0.00087 kgm. Siemens documentation specifies approximately 6 kg for the stator with cooling jacket and 1.15 kg for the rotor, giving approximately 7.15 kg combined weight without the rotor sleeve. The motor uses Pt1000 temperature sensing for thermal monitoring and has a thermal time constant of approximately 1 minute. The configuration is designed for integration with a suitable stator, rotor, cooling system, and SINAMICS S120 drive system.
