Determining the effect of grain size and maximum induction upon coercive field of electrical steels
(ELSEVIER SCIENCE BV, 2011)
Although theoretical models have already been proposed, experimental data is still lacking to quantify the influence of grain size upon coercivity of electrical steels. Some authors consider a linear inverse proportionality, ...
Análise da deformação dinâmica de um estator de um motor de indução trifásico empregando sensores de rede de Bragg em fibra óptica
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2018-06-20)
A three-phase induction motor in operation, through mechanical and electrical forces, can cause deformation in the stator, which can generate undesirable vibration problems. These problems generate wear on the machines ...
Gerador de indução isolado com tensão e freqüência reguladas por conversor matricial esparso
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2008-06-30)
The induction generator has characteristics making it interesting for alternative sources of energy, such as low cost, ruggedness, low maintenance, high availability and good dynamic behavior. So, it is very much applied ...

Voltage unbalance and harmonic distortion effects on induction motor power, torque and vibrations
(Elsevier Science Sa, 2016-11)
Voltage unbalance and harmonic voltage distortion affect the power, torque and vibrations on induction motors (IM). In this paper, we compute the frequency of the oscillations of the power, torque and vibrations due to ...
Salmonella Enteritidis infection, corticosterone levels, performance and egg quality in laying hens submitted to different methods of molting
(2019-10-01)
In commercial layer poultry farming, molt induction is an important tool used by egg producers to prolong the production cycle of laying hens. Conventional molt induction programs involve total feed withdrawal, which raises ...
Optimizing Transcutaneous Energy Transmitter Using Game Theory
(2016-03-01)
Over the past recent years, several studies, seeking reliable Transcutaneous Energy Transmitters (TETs), have used different types of optimization techniques with different objectives. Algorithms with multiple objectives ...
