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

These harmonics are due to different effects, mechanical and electrical, as has been reported for some time 58. Instrumentation The measurement system has the following elements: Kral et al 6 proposes a technique to estimate unbalance using rotoers that are present in the electric power, showing positive results in assessing static and dynamic unbalance.

Bellini rotorse presents a paper review of the previous ten years showing a list of references and research activity classified in four topics: Balanceo en un plano 6. Amazon Giveaway allows you to run promotional giveaways in order to create buzz, reward your audience, and attract new followers and customers.
Vol 2, Issue 1, Balancro 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. Don’t have a Kindle? Calidad del balanceo 9. Measurements of residual- current signals A residual current is considered as the remaining harmonics after subtracting the fundamental current circulating in a motor wiring.
BALANCEAMIENTO DE ROTORES by Carlos Cayo Mamani on Prezi
The relationship among the spectral harmonics of an electric current induction motor, and its mechanical and electromagnetic problems is well known. It then calculates the harmonics R 01R 02R 03 related to the resultant unbalance.

These currents are produced by a deformation of the magnetic field in the motor air-gap, as a result of mechanical unbalance. 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. This is performed in dinamifo similar way as the previous step. 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:.

Proposed balancing method From equations 3 and 4it gets: Cantidad de desbalanceo 4. Write a customer review. English Choose a language for shopping. The signal readings, which are scalar quantities that reflect residual complex values offset with magnitude and phase when dinaico is no imbalance, produce a nonlinear behavior of the data with respect to the unbalanced forces.

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 fulfilling the vibration standards for the particular rotor in turn. The procedure requires three trial weights to carry on balancing. Figures 1 and 2 show some of the displays. Camargo 9 presents results of single-plane rotor balancing using electric dijamico that relate to mechanical unbalance. It recycles iteration to step 2.
The other difficulty is nonlinearity behavior of data due to an offset. 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. Read more Read less.

Equations 35 and 36 provide another compatibility condition that allows the determination of the desired solution to the balancing problem.
This is a compatibility condition for harmonics related with L 1L 2. Set up a giveaway. The electric signal is obtained using Hall-effect probes model M15 which have a range of 10 kHz.
Table 4 shows estimated balance masses for each test case to rotoes with the expected value. Applications Several tests were conducted using an induction motor described in Table 1. 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.
