rotorból

Rotorból is a term occasionally used in mechanical engineering literature to describe phenomena or effects that originate from a rotor and propagate to other parts of a rotating machine or its structure. The word is formed from the word rotor and the Hungarian suffix -ból, meaning “from” or “out of.” In this sense, rotorból refers to the outward dynamic loads, vibrations, and signals that arise from rotor operation rather than from stationary components.

The concept encompasses a range of rotor-originated effects. These can include mechanical vibrations transmitted through bearings and housings, aerodynamic or hydrodynamic wakes generated by rotor motion, and electromagnetic or acoustic signals linked to rotor speed, imbalance, or misalignment. Rotorból phenomena are of interest because they can affect component life, noise levels, efficiency, and overall machine reliability.

Measurement and modeling are used to analyze rotorból effects. Techniques include modal analysis, finite-element modeling, and time- or frequency-domain simulations. Experimental methods such as accelerometers, strain gauges, and laser vibrometry help quantify rotor-originated responses. Diagnosing rotorból is common in rotor-dynamics studies, condition monitoring, and maintenance planning, where reducing transmitted loads and improving balancing and alignment can extend service life and reduce downtime.

Note that rotorból is not a universally standardized term; it appears mainly in some Hungarian-language texts and discussions on rotor dynamics. In other contexts, the phenomena described may be labeled as rotor-induced response or rotor-originated vibration.
