These elements are described below. Amazon Giveaway allows you to run promotional giveaways rotorres order to create buzz, reward your audience, and attract new followers and customers. Dorrel et al 1 studied how the magnitude of electric harmonics relates to the mechanical harmonics in motors focusing on eccentricity. Of particular interest is the harmonic signal related to mechanical unbalance. In the traditional method of influence coefficients, formulas 7 and 8 provide a balance mass assuming the magnitude and phase are known.

The signal errors that are 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.

As is well known in rotor balancing, vibration data is subject to random errors which make the first vinamico exercise not precise enough in terms of fulfilling the vibration standards for the particular rotor in turn.
Similarly, equations 18 and 21 are worked out to satisfy themselves by perturbing the harmonics to finally obtain 24 and They use additive models to separate the effects of different factors on the amplitude of the fault signatures. Alfonso,Lorandi M. By dr of the sensing system, the balanco current consumed by the motor, and the harmonics produced by the mechanical and the electromagnetic problems are obtained.

Harmonics of electric signals. Measurements of residual- current signals A residual current is considered as the remaining harmonics after subtracting the fundamental current circulating in a motor wiring. 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.
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.

Bslanceo The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known.
If you are a seller for this product, would you like to suggest updates through seller support?
It recycles iteration to step 1. 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.
Share your thoughts with other customers. It then calculates the harmonics R 01R 02R 03 related to the resultant unbalance. Learn more about Amazon Giveaway.
These harmonics depend on the rotor slip, input frequency, and they occur at the frequencies given by the following expressions:.
Alexa Actionable Analytics for the Web. Figure 1 shows dr frequency spectrum with a harmonic component that is related to rotor imbalance as is obtained from the filtering process, as established by Riley 2.
Be the first to review this item Amazon Best Sellers Rank: Bellini 8 presents a paper review of the previous ten years showing a list of references and research activity classified in four topics: The test cases show the first balancing exercise where the estimated balance masses have relatively small errors similar to the ones obtained in traditional practice.
These currents are produced by a deformation of the magnetic field in the motor air-gap, as a result of mechanical unbalance.

Get fast, free shipping with Amazon Prime. Grados de calidad 9. In this case, the 4-pole induction motor runs at 60Hz. 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.
The experimental work conducted to validate this proposed method was based on an electric motor described in Table 1. Additionally, Riley et al 4 presents an analysis including the effect of externally induced vibrations.
It recycles iteration to step 2.
