While wind energy is inherently variable, its small decline last year comes at a moment of flux for US electricity generation. The US is witnessing rapid power demand growth for the first time in ...

New features like var, auto-compile, text blocks, record classes, and more are shifting Java in subtle but powerful ways—toward a more flexible, dynamic future. Java has made some big shifts ...

From the classic Lissajous pattern to measure phase or frequency ratios, to state transition diagrams for modern quadrature ... to generate a signal with a variable phase. Two signals added in ...

In this paper, we focused on the modeling and control of variable speed wind turbine that is composed of two-mass drive train, a Squirrel Cage Induction Generator (SCIG), and voltage source converter ...

Abstract: Variable flux machines (VFMs) have one more dimension for the control ... This paper presents a method based on vector control for the characterization of a VFM. An existing drive is used to ...

But this back-EMF shape is harder to achieve in motor design than sinusoidal back-EMF since the airgap flux would need to be held constant ... magnetic axes for each phase on a space vector diagram, a ...

Both open loop and sensorless flux vector control can be applied to induction and BLDC motors alike. What are the control's subcomponents? A typical block diagram of sensorless vector control ...

Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...
