Next, a set of relations involving perturbations is xe Tipos de balanceo 5. Vol 2, Issue 1, This is a compatibility condition for harmonics related with L 1L 2. Cantidad de desbalanceo 4.

Circle after data perturbations. It recycles iteration to step 1. The electric signal is obtained using Hall-effect probes model M15 which have a range of 10 kHz.

The measurement system has the following elements: These vectors are measured in magnitude, and their measured phase angles are relative. Substituting in the trigonometric identity that the sum of the squares is equal to one, one gets:. Amazon Rapids Fun stories for kids on the go.

There is a unique vector combination that fulfills this condition, and thus the absolute phase angles are determined. East Dane Designer Men’s Fashion.

Proposed balancing method From equations 3 and 4it gets: The measurement consists of a virtual instrument, a set of solid-state magnetic sensors and its signal conditioning. Kral et al 6 proposes a technique to estimate unbalance using harmonics that are present in the electric power, rotorse positive results in assessing static and dynamic unbalance.

The balance technique that is presented here is unique in handling residual current as input data, and it is dinamicp subject to measurement errors. Depending on harmonic order, there is an associated mechanical or electromagnetic problem. Similarly, equations 18 and 21 are worked out to satisfy themselves by perturbing the harmonics to finally obtain 24 and 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.

Introduction The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known. 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.

The virtual instrument developed in this work offers a low cost and a user-friendly interface, and thus a remarkable potential for industrial applications. Several tests were conducted using an induction motor described in Table 1. Set up a giveaway.

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. Figure 2 shows the three harmonic components in a polar diagram. English Choose a language for shopping.

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.
