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.

This requires an algorithm to determine, based on readings of residual values for the balanced condition, and the imbalanced rotor, the complex values that directly relate to the imbalance.

Iteration is done until it finds the best approximation to the unbalance mass obtained previously in step 3.

This is a compatibility condition for harmonics related with L 1L 2. 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.

This algorithm was rotorws by running several study cases, with the same order of precision of the traditional balance method that uses vibration data.

Advances in Diagnostic Techniques for Induction Machines.

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. This is performed in a similar way as the previous step. Circle after data perturbations. However, when unbalance ispresent these relative phase angles change due to the vector sum of the offset and dianmico unbalance effect.

Would you like to tell us about a lower price? There is a unique vector combination that fulfills this condition, and thus the absolute phase angles are determined.

These harmonics are due to different effects, mechanical and electrical, as has been reported for some royores 58. East Dane Designer Men’s Fashion.

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 dinamoco the vibration standards for the particular rotor in turn.

Abstract 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. Calidad del balanceo 9. ComiXology Thousands of Digital Comics.

G and Kliman G. Vol 2, Issue 1, The experimental work conducted to validate this proposed method was based on an electric motor described in Table 1. Having determined the harmonic phases, it balanveo 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.

Alfonso,Lorandi M. In the end, one obtains a solution for the minimum sum of squares of the perturbations. 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.

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. Recorded data using the virtual instrument described above are shown in Tables 2 and 3. May 26, ; Accepted: Algorithm description The numerical procedure consists of the following steps: Of particular interest is the harmonic signal related to mechanical unbalance.

When direct measurements are included, vectors may look like shown in Figure 4 and their equations are:. 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. Amazon Restaurants Food delivery from local restaurants. The other difficulty is nonlinearity behavior of data due to an offset.

It recycles iteration to step 2. Set up a giveaway. There’s a problem loading this menu right now. 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. It recycles iteration to step 1.
