BALANCEO DINAMICO DE ROTORES PDF
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.

Withoutabox Submit to Film Festivals. An improvement of a single-plane balancing method via residual current of a rotor directly coupled to an induction motor. It recycles iteration to step 1. Set up a giveaway. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Iteration is done until it finds the best approximation to the unbalance mass obtained previously in step 3.
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. Neelam 7 presents an analysis of the electric current as the most popular for failure diagnosis, not only electrical but also mechanical as well, showing effectiveness to determine abnormal operation of induction motors, including situations involving gear trains. Algorithm description The numerical procedure consists of the following steps: Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:.
It has been reported the phase relation among high order harmonics near 90Hz which tend toz ero with some variations that depends on the degree of rotor unbalance. Linand Thomas G. 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.
BALANCEAMIENTO DE ROTORES by Carlos Cayo Mamani on Prezi
Conclusions Based on previous works in the literature, where a relationship between the mechanical unbalance and the electric-current harmonics is reported, this article develops a more efficient method of balancing that takes into account the r. ComiXology Thousands of Digital Comics. These vectors are measured in magnitude, and their measured phase angles are relative. As is well known in rotor balancing, vibration data is subject to random errors which make the first balancing exercise not precise enough in terms of fulfilling the vibration standards for the particular rotor in turn.
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. Balanceo en dos planos 6. Amazon Inspire Digital Educational Resources. Hall-effect probes for electric current, signal conditioning, data acquisition system, and virtual instrument developer in G language. Circle before data perturbations.
Next, a set of relations involving perturbations is developed: If you are a seller for this product, would you like to suggest updates through seller support? Riley et 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.

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.

Amazon Giveaway allows you to run promotional giveaways in order to create buzz, reward your audience, and balancei new followers and customers.
Proposed balancing method From equations 3 and 4it gets: To illustrate bbalanceo procedure, the following exercise is conducted for one test case. Equations dlnamico and 36 provide another compatibility condition that allows the determination of the rotored solution to the balancing problem. 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.
Tipos de balanceo 5. The procedure requires three trial weights to carry on balancing. They use additive models to separate the effects of different factors on the amplitude of the fault signatures. 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.
