Siemens SIMOTICS M 1FE1 Built-In Synchronous Motor About

The Siemens 1FE1052-4HD30-1BA2 is a SIMOTICS M 1FE1 four-pole built-in synchronous motor designed for high-speed precision spindle and machine-tool applications. It is a permanent-magnet synchronous motor intended for integration into high-performance spindle assemblies and operation with Siemens drive technology. The motor is designed for water cooling and a 600 V DC-link system, providing effective thermal management during demanding high-speed operation. Its construction is optimized for compact installation, high power density, accurate speed control, and reliable continuous operation. The 1FE1052 motor family is particularly suited to CNC machine tools, precision grinding, high-speed machining centers, and industrial spindle applications. The -4HD30-1BA2 configuration represents a specific stator/rotor and cooling arrangement, so exact rated power, torque, speed, dimensions, and weight should be taken from the Siemens-specific MLFB datasheet rather than inferred from another 1FE1052 variant. This configuration is intended for professional industrial applications where high rotational speed, low rotor inertia, precise positioning, and reliable thermal performance are required.
