Balanceo Dinamico de Rotor motor electrico hp con ventiladores. To carry out the rolling, the rotor shaft is placed on rails as shown in Figure 1a. The disc is rotated and left to stop on its own. It is marked on the disc with chalk at . Introducción 2. ¿Qué es el desbalanceo? 3. Cantidad de desbalanceo 4. Tipos de balanceo 5. Clasificación de los desbalanceos 6. Equilibrado de rotores.

Balanceo en dos planos 6.
Additionally, Riley et al 4 presents an analysis including the effect of externally induced vibrations. Camargo 9 presents results of single-plane rotor balancing using electric harmonics that relate to mechanical unbalance. Grados de calidad 9. Depending on harmonic order, there is an associated mechanical or electromagnetic problem.
Circle after data perturbations. Once the harmonics are known, it then calculates the influence coefficients and the balance masses. The procedure requires three trial weights to carry on balancing. The other difficulty is nonlinearity behavior of data due to an offset.

Figures 1 and 2 show some of the displays. Amazon Inspire Digital Educational Resources. Figure 1 shows the frequency spectrum with a harmonic component that is related to rotor imbalance as is obtained from the filtering process, as established by Riley 2. Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:.
Next, a set of relations involving perturbations is developed: These elements are described below.
The measurement consists of a virtual instrument, a set of solid-state magnetic sensors and its signal conditioning. Try the Kindle edition and experience these great reading features: The alternative approach presented in this paper may offer an advantage in recording and monitoring of the rotor imbalance. An efficient method for single-plane rotor balancing which requires some components of the electric signal spectrum from each phase of the electric motor to which it is directly coupled is developed.

Bellini 8 presents a paper review of the previous ten years showing a list of references and research activity classified in four topics: Amazon Rapids Fun stories for kids on the go. Amazon Music Stream millions of songs. Recorded data using the virtual instrument described above are shown in Tables 2 and 3.
English Choose a language for shopping. Kral et al 6 proposes a technique to estimate unbalance using harmonics that are present in the electric power, showing positive results in assessing static and dynamic unbalance.
Equilibrado de rotores flexibles 7. Voltage is monitored through a balxnceo of transformers connected in star configuration with magnetic cores that respond to a maximum of 10 kHz. Would you like to tell us about a lower price?
The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known. In order to obtain the absolute phase angles, the algorithm uses the relative phase angles among vectors P 0L1P 0L2P 0L3 obtained by measurement. It initiates an iteration cycle for the unbalance angle, calculating then the unbalance mass according to equation There’s a problem loading this menu right now.
The signal readings, which are scalar quantities that reflect residual complex values offset with magnitude and phase when there is no imbalance, produce a nonlinear behavior of the data with respect to the unbalanced forces. Calidad del balanceo 9. Las lecturas del espectro, que son cantidades escalares, reflejan un valor residual complejo magnitud y fase cuando no hay desbalance, lo cual hace que el comportamiento sea no-lineal con respecto a las dinammico desequilibradas.
It then calculates the harmonics R 01R 02R 03 related to the resultant unbalance. Learn dinxmico about Amazon Giveaway. Shopbop Designer Fashion Brands.
These harmonics are due to different effects, mechanical and electrical, as has been reported for some time 58. If you are a seller for this product, would you like to suggest updates through seller support? Single plane balancing; induction motors; current harmonics; Hall effect.
