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.

The magnitudes of the signal spectrum do not have a linear homogeneous relationship with the unbalance force due to a complex offset that can be measured with the balanced rotor, and that adds to the unbalance effects.
Balnaceo, Riley et al 4 presents an analysis including the effect of externally induced vibrations. May 26, ; Accepted: However, the residual condition is also obtained by motor eccentricity, asymmetry of coil structure of stator and rotor, that is, owing to static and dynamic irregularities in the air-gap 258. English Choose a language for shopping. Composition of harmonic vectors.
Introduction The relationship among the spectral harmonics of balancek electric current induction motor, and its mechanical and electromagnetic problems is well known. This is an open-access article distributed under the terms of the Creative Commons Attribution License. The measurement system has the following elements: Camargo 9 presents results of single-plane rotor balancing using electric harmonics that relate to mechanical unbalance.
Alexa Actionable Analytics for the Web. The measurement consists of a virtual instrument, a set of solid-state magnetic sensors and its signal conditioning.
Bellini 8 presents a dijamico review of the previous ten years showing a list of references and research activity classified in four topics: Read more Read less. Amazon Inspire Digital Educational Resources. Dorrel et al 1 studied how the magnitude of electric harmonics relates to the mechanical harmonics in motors focusing on eccentricity.
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. Voltage is monitored through a set of transformers connected in star configuration with magnetic cores that respond to a maximum of 10 kHz. In the traditional method of influence coefficients, formulas 7 and 8 provide a balance mass assuming the magnitude and phase are known. Cantidad de desbalanceo 4.
Equations 35 and 36 provide another compatibility condition that allows the determination of the desired solution to the balancing problem.
BALANCEAMIENTO DE ROTORES by Carlos Cayo Mamani on Prezi
Get fast, free shipping with Amazon Prime. This balancing technique faces two problems; one is data variations of samples which are solved by taking three to five minute samplings, and calculating the r.
This is performed in a similar way as the previous step. Get to Know Us. There is a unique vector combination that fulfills this condition, and thus the absolute phase angles are determined. The procedure requires three trial weights to carry on balancing. Learn more about Amazon Prime. East Dane Designer Men’s Fashion. These harmonics depend on the rotor slip, input frequency, and they occur at the frequencies given by the following expressions:.
The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known. The other difficulty is nonlinearity behavior of data due to an offset.
These vectors are rotords in magnitude, and their measured phase angles are relative. Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:.

Table 4 shows estimated balance masses for each test case to compare with the expected value. 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.
Withoutabox Submit to Film Festivals. 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.
