Many geared electric drives can benefit from removing the gearbox and driving directly the load at low speed using a permanent-magnet synchronous machine (PMSM). PMSMs with non-overlapping concentrated windings are particularly attractive in low-speed direct drives since they allow, among other advantages, a high number of poles with a limited number of slots. Therefore, this thesis is dedicate...

in this paper, we discuss the ways that communication accommodation theory (cat) can be a useful framework for understanding and diagnosing interactional issues in interpersonal and intergroup conflict situations. we argue that the theory’s construct of attuning strategies provides a multidimensional view of mutual adjustment, leading to insights relevant to successful versus unsuccessful confl...

Using a generalization of the skew-product representation of planar Brownian motion and the analogue of Spitzer’s celebrated asymptotic Theorem for stable processes due to Bertoin and Werner, for which we provide a new easy proof, we obtain some limit Theorems for the exit time from a cone of stable processes of index α ∈ (0, 2). We also study the case t → 0 and we prove some Laws of the Iterat...

The analysis and comparation of the half-coiled short-pitch windings with different phase belt are presented in the paper. The half-coiled short-pitch windings can supply the odd and even harmonics simultaneously, which can be applied in multiphase bearingless motor (MBLM). The space harmonic distribution of the half-coiled short-pitch windings with two kinds of phase belt is studied wi th resp...

The purpose of the magnet is to provide a uniform magnetic field at all points in the bore of the magnet to align mobile protons within the patient. The strength of the magnetic field is measured in units of testa or gauss-1.0 T equals 10 000 G. The magnetic field produced by the magnet is typically 30 000 times stronger than the magnetic field of the earth. Because it is not possible to obtain...

The squared-field-derivative method for calculating eddy-current (proximity-effect) losses in round-wire or litz-wire transformer and inductor windings is derived. The method is capable of analyzing losses due to two-dimensional and three-dimensional field effects in multiple windings with arbitrary waveforms in each winding. It uses a simple set of numerical magnetostatic field calculations, w...
