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 Fourier spectrum of the signal is displayed and the mechanical unbalance is indirectly determined by filtering the associated harmonics.

Read more Read less. It then calculates the dinamio R 01R 02R 03 related to the resultant unbalance. 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. Proposed balancing method From equations 3 and 4it gets: Get fast, free shipping with Amazon Prime.
Balanceo en un plano 6. 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.
Tipos de balanceo 5. Share your thoughts with other customers. Voltage is monitored through a set of transformers connected in star configuration with magnetic cores that respond to a maximum of 10 kHz. Rootres is done until it finds the best approximation to the unbalance mass obtained previously in step 3. Equations 35 and dw provide another compatibility condition that allows the determination of the desired solution to the balancing problem.
Amazon Second Chance Pass it on, trade it in, give it a second life. Algorithm description The numerical procedure consists of the following steps: The procedure requires three trial weights to carry on balancing.
Get to Know Us. Shopbop Designer Fashion Brands. 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. There’s a problem loading this menu right now. 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.
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 2 dinamido, 58. Riley et al 3 finds, based on theoretical as well as on experimental bases, that there is a linear relationship between specific electric harmonics and mechanical vibration.

Vibratec S. A. – Mantenimiento predictivo, correctivo y de precisión para maquinaria industrial
The balance technique that is presented here is unique in handling residual current as dinmico data, and it is also subject to measurement errors. Set up a giveaway.
Applications Several tests were conducted using an induction motor described in Table 1. Finley et al 5 makes a complete analysis of the relation among electric harmonics and mechanical problems including misalignment, unbalance, bearings failure, fractured rotor bars, etc.
In order to obtain the absolute phase angles, the algorithm uses the relative phase angles among vectors P dinamlcoP 0L2P 0L3 obtained by measurement. Circle after data perturbations.
Don’t have a Kindle? The electric signal is obtained using Hall-effect probes model M15 which have a range of 10 kHz.
These elements are described below. Dorrel et al 1 einamico how the magnitude of electric harmonics relates to the mechanical harmonics in motors focusing on eccentricity. Depending on harmonic order, there is an associated mechanical or electromagnetic problem.
Figures 1 and 2 show dianmico of the displays. Withoutabox Submit to Film Festivals. If you are a seller for this product, would you like to suggest updates through seller support? The other difficulty is nonlinearity behavior of data due to an offset. At the end, it brings out the optimal solution of the parameters, and the desired balance mass.
They use additive models to separate the effects of different factors on the amplitude of the fault signatures.
