Abstract Wind power turbines have increasingly attracted attention as a renewable energy source. Gearboxes in wind reduce their efficiency, require periodic maintenance, and result gearbox failure. Consequently, direct-driven generators with high torque density emerged an alternative because they transmit the of turbine directly. Permanent-magnet vernier machines (PMVMs) possess simple robust s...

Synchronous generators are of two type’s salient pole type and round rotor type. The load angle curve of a cylindrical rotor synchronous machine comprises a single sine term only while in salient pole synchronous generators, power-angle characteristic has two terms. The first term is the fundamental component due to field excitation (the same as the cylindrical rotor) and the second term ...

[1] We study, by using a wavelet decomposition methodology, the solar signature on global surface temperature data using the ACRIM total solar irradiance satellite composite by Willson and Mordvinov. These data present a +0.047%/decade trend between minima during solar cycles 21–23 (1980–2002). We estimate that the ACRIM upward trend might have minimally contributed 10–30% of the global surface...

Aim: to reveal hereditary mutations in patients with adenomatous polyps of the gastrointestinal tract. Patients and methods: a retrospective cohort study included 8 tract (ranging from 4 several hundred). The APC, AXIN2, BMPR1A, BRCA2, CDH1, CHEK2, EPCAM, GALNT12, GREM1, MLH1, MLH3, MSH2, MSH3, MSH6, MutYH, NTHL1, PMS2, POLD1, POLE, SMAD4, STK11 genes were studied using new generation sequencin...

 This article proposes a new dual-sided permanent magnet (DSPM) machine with flux-concentrated U-shaped magnets (PMs) in stator, and consequent-pole PMs rotor, respectively. The proposed DSPM can perform bidirectional field modulation effect (BFME) to enhance the effective harmonics, hence improving torque capability. A magneto-motive force-permeance based model is employed reveal produc...

In this paper, a new design of permanent magnet linear synchronous motor (PMLSM) for electromagnetic launcher system (EMLs) has been investigated in terms of the requisite amount of average launching thrust force and thrust force ripple minimization through finite element method. EMLs are a kind of technology used to develop thrust force and launch heavy loads with different applications includ...
