Magnification of starting torques of dc motors by maximum power point trackers in photovoltaic systems [PDF]

open access: yes
Direct current (dc) motors are used in terrestrial photovoltaic (PV) systems such as in water-pumping systems for irrigation and water supply. Direct current motors may also be used for space applications.

Effects of causal beliefs about gout on public views about gout management: A randomized experimental study

open access: yesArthritis Care &Research, Accepted Article.
Objective Despite well‐described biological causes, the public views unhealthy lifestyle choices as the primary cause of gout. This study investigated how causal beliefs about gout influence the public's views about its management. Methods In a randomized study, 201 members of the public viewed one of two 2‐minute videos about gout.

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Brush Less Dc Motor

open access: yes, 2019
Permanent Magnet PM Brushless DC BLDC motors have been widely used in industrial drives due to their high performance, high torque density and low acoustic noise. Cogging torque in these motors is caused by the reluctance change between the stator teeth and the rotor magnets.
