The purpose of this paper is to study the influence of the type of winding - double layer or single layer - to the global noise level of the machine. For this purpose, two variable speed induction motors have been studied, of the type M3AA 71 B4/8 manufactured by Electroprecizia S.A. Săcele, Romania, with Dahlander windings, star connected - for theâ€¦ (More)

The analytical model for hysteresis cycle of soft magnetic materials using arcs of circle and straight line segments presented in [2] has been improved to minimize the error between the measured and modelled one. The LabVIEW program has been improved to be more user-friendly. For the new model presented in this paper, the data that are necessary forâ€¦ (More)

This paper deal with a modified Preisach model. The classical Preisach model is a great tool in the modeling of magnetic proprieties of a magnetic material which is used in practice. The main problem of this model is to find the Preisach function also called distribution function. In the classical Preisach models the distribution function is determinedâ€¦ (More)

The paper deals with an analytical model for hysteresis cycle representation. The hysteresis curve is decomposed in a series of arcs of circles and segments of lines. Each arc of circle or segment of line is expressed using analytical geometry as a function of some given parameters or calculated ones. The easiness of the model proposed is given by the smallâ€¦ (More)

The paper deal with Steinmetz power losses equation developed in LabVIEW program. The initial equation is used after the area of hysteresis cycle is calculated using the LabVIEW VI's. It is important to have enough points considered on the major hysteresis loop to obtain with good accuracy the power losses. For this reason we use some VI's to interpolateâ€¦ (More)
