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.

These currents are produced by a deformation of the magnetic field in the motor air-gap, as a result of mechanical unbalance. Bellini 8 presents a paper review of the previous ten years showing a list of references and research activity classified in rtores topics: Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:.

Equilibrado de rotores flexibles 7. Amazon Rapids Fun stories for kids on the go. Voltage is monitored through a set of transformers connected in star configuration with magnetic cores that respond to a maximum of 10 kHz.
Depending on harmonic order, there is an associated mechanical or electromagnetic problem. The signal errors that balsnceo present in the readings, more pronounced in these Hall-type sensors, are decreased by means of a system of equations of perturbations and compatibility relations that are applied to these data.
Tipos de balanceo 5.
Iteration is done until it finds the best approximation to the unbalance mass obtained previously in step 3. Instrumentation The measurement system has the following elements: Algorithm description The numerical procedure consists of the following steps: It initiates an iteration cycle dianmico the unbalance angle, calculating then the unbalance mass dinamco to equation Measurements of residual- current signals A residual current is considered as the remaining harmonics after subtracting the fundamental current circulating in a motor wiring.
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.

An improvement of a single-plane balancing method via residual current of a rotor directly coupled to an induction motor. An efficient balancep for single-plane rotor balancing which requires balancceo components of the electric signal spectrum from each phase of the rotires motor to which it is directly coupled is developed.
The procedure requires three trial weights to carry on balancing. English Choose a language for shopping. The electric signal is obtained using Hall-effect probes model M15 which have a range of 10 kHz.

Additionally, Riley et al 4 presents an analysis including the effect of externally induced vibrations. Composition of harmonic vectors. These elements are described below. Figures 1 and 2 show some of the displays.
These harmonics depend on the rotor slip, input frequency, and they occur at the frequencies given by the following expressions:. Write a customer review. AmazonGlobal Ship Orders Internationally. This balancing technique faces two problems; one is data variations of samples which are solved by taking three to five minute samplings, and calculating dinsmico r.
It recycles iteration to step 1. 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.
These harmonics depend on the rotor slip, input frequency, and they occur at the frequencies given by the following expressions: Harmonics of electric signals. Given the unbalance and resultant angles according to the iterationsand the trial mass, the magnitudes of the unbalance mass and the resultant may be solved as follows:.

A residual current is considered as the rinamico harmonics after subtracting the fundamental current circulating in a motor wiring. 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. G and Kliman G. Alexa Actionable Analytics for the Web. Dorrel et al 1 studied how the magnitude of electric harmonics relates to the mechanical harmonics in motors focusing on eccentricity.
