The other difficulty is nonlinearity behavior of data due to an offset. Figure 2 shows the three harmonic components in a polar diagram. Share your thoughts with other customers.
Similarly, equations 18 and 21 are worked out to satisfy themselves by perturbing the harmonics to finally obtain 24 and Be the first to review this item Amazon Best Sellers Rank: For diagnosis purposes, software ANOVA allows the subtraction of the contribution of a variable in the fault signature value, avoiding a bias produced by this variable.

Applications Several tests were conducted rottores an induction motor described in Table 1. 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 fuerzas desequilibradas.
East Dane Designer Men’s Fashion. Alfonso,Lorandi M. Bellini 8 presents a paper review of the previous ten years showing a list of references and research activity classified in four topics: It initiates an iteration cycle for the unbalance angle, calculating then the unbalance mass according to equation AmazonGlobal Ship Orders Internationally.
May 26, ; Accepted: The balance technique that is presented here is unique in handling residual current as input data, and it is also subject to measurement errors.
Having determined the harmonic phases, it is possible to calculate the influence coefficients as well as the balance masses for each combination of trial weights. 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.
Traditional balancing Having determined the harmonic phases, it is possible to calculate the influence coefficients as well as the balance masses for each combination of trial weights. Shopbop Designer Fashion Brands.
Circle after data perturbations.
Riley dinanico al 2 analyzed these relations to establish limits for the electric harmonics as they correlate with vibrations, concluding that there is a monotone relationship between both variables. This is performed in a similar way as the previous step. An improvement of a single-plane balancing method via residual current of a rotor directly coupled to an induction motor. In the traditional method of influence coefficients, formulas 7 and 8 provide a balance mass assuming the magnitude and phase are known.

Introduction The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known. The measurement system has the following elements: By means of the sensing system, the fundamental current consumed by the motor, and the harmonics produced by the mechanical and the electromagnetic problems are obtained.
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. Single plane balancing; induction motors; current harmonics; Hall effect. Linand Thomas G. These harmonics depend on the rotor slip, input frequency, and they occur at the frequencies given by the following expressions: Composition of harmonic vectors.
Next, a set of relations involving perturbations is developed: The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known.

It is designed for volts and a maximum of 15 amperes. There’s a problem loading this menu right now. This is an open-access article distributed under the terms of the Creative Commons Attribution License. In the end, one obtains a solution for the minimum sum of squares of the perturbations.
BALANCEAMIENTO DE ROTORES by Carlos Cayo Mamani on Prezi
Alexa Actionable Analytics for the Web. Several tests were conducted using an induction motor described in Table 1. Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:. Algorithm description The numerical procedure consists of the following steps: Cantidad de desbalanceo 4.
