The Siemens 1FK7042-5AF71-1GA2 motor within the 1FK7 series is designed for efficient operation in various industrial scenarios. Rated for 400V AC voltage, it maintains an impressive speed of 3000 RPM. Power output is rated at 0.75 kW, allowing for effective energy management while delivering a torque rating of 2.5 Nm.

Precision is enhanced through the integration of an absolute 24-bit encoder, providing high-resolution feedback to the system. The motor has a compact design and is suited for flange mounting, which facilitates straightforward installation. Weighing only 3.8 kg, the unit is robust yet lightweight.

With an IP65 rating, this motor is protected against dust and low-pressure water jets, making it suitable for applications that require durability in less-than-ideal conditions. It functions well across a broad temperature range of 0°C to 40°C. Additionally, it can withstand vibrations up to 2 g across a frequency range of 10 to 500 Hz.

The motor's shaft is a straight design equipped with a keyway to ensure proper alignment and fixity to the application. An overload capacity of 250% is permissible for a brief period of three seconds, which can be beneficial in applications that experience transient loads.
