A Model for Induction Motors with Non-Uniform Air-Gap
(Planta Piloto de Ingeniería Química, 2005-12)
Equations to calculate inductances of induction motors, considering non-uniform air-gap, are proposed. The analyzed air-gap variations are static and dynamic eccentricity and stator slots. The equations for inductance ...
Dynamic behavior of a linear induction motor
(1998-12-01)
Although conventional rotating machines have been largely used to drive underground transportation systems, linear induction motors are also being considered for future applications owing to their indisputable advantages. ...
SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION
(Soc Brasil Engenharia Agricola, 2018-03-01)
The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely ...
Evaluation of Low-Drift Nozzles in Agrochemical Applications in Orchards
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Application of an Additional Excitation in Inverter-Fed Induction Motors for Air-Gap Eccentricity Diagnosis
(Institute of Electrical and Electronics Engineers, 2006-12)
In this paper, the application of an additional excitation in induction motor (IM) drives for static, dynamic, and mixed eccentricity diagnosis is proposed. The additional excitation consists in a predefined inverter-switching ...
Photosynthetic limitations caused by different rates of water-deficit induction in Glycine max and Vigna unguiculata
(Springer, 2012-09-01)
Plants are constantly subjected to variations in their surrounding environment, which affect their functioning in different ways. The influence of environmental factors on the physiology of plants depends on several factors ...
Droplet spectrum generated by air induction nozzles spraying solutions containing adjuvants and a tank mixture of glyphosate and dicamba
(2020-01-01)
The aim of this work was to evaluate drift reduction technologies (DRTs) by analyzing the droplet spectrum generated by air induction nozzles spraying solutions containing adjuvants and a mixture of glyphosate and dicamba. ...
Dicamba Spray Drift as Influenced by Wind Speed and Nozzle Type
(Cambridge Univ Press, 2017-09-01)
With the release of dicamba-resistant crops, it is necessary to understand how technical and environmental conditions affect the application of dicamba. This study sought to evaluate drift from dicamba applications through ...
