The Siemens 1FK7042-5AK71-1AA3 synchronous servomotor is built for high-performance applications, providing reliable operation with a rated output power of 1.02 kW. It generates a nominal torque of 3.0 Nm under varying load conditions. This motor maintains efficiency and functionality by employing natural cooling methods to manage temperature. The protection ratings ensure suitability for diverse environments, with an IP65 rating for the motor itself and IP67 for the flange, allowing for protection against dust and water ingress.
Operating at a maximum rated speed of 6000 RPM, it supports high-velocity applications seamlessly. The motor's shaft height is specified at 48 mm, using a fitted key type with a tolerance of N to ensure proper fit and function within assemblies. It can be mounted typically in the IM B5 configuration, but it also supports alternate mounting types such as IM V1 and IM V3, providing flexibility in installation.
The incremental encoder used in this motor is designed to comply with SIN/COS standards, delivering a signal with a resolution of 1 Vpp, enabling accurate motion control with 2048 pulses per revolution. A notable connector rotation of 270° further facilitates efficient wiring configurations. With a total weight of 4.8 kg, this servomotor combines compactness with effective performance, making it a compelling choice for dynamic control systems in industrial settings.
