Hi, I am interested in learning more about the actual current flow and voltage differnces between the Delta connected load or motor and the star or (wye) connected load or motor. I am after a web site that has a good reference to the formulas and characteristics of the 3 phase star (wye) / delta motor starting principle. I have read tech books on the subject but haven't found an online reference site. The reference site would also have information that informs of the different methods that motor manufacturers use to bring out the winding leads of 3 phase motors and how they are connected internally either by using the star or delta methods, or end user selectable (using jumper links across the terminal posts). Any info on this subject is appreciated Thanks in advance.

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
This whitepaper describes the role of thermal transient measurement to characterize semiconductor thermal behavior. It focuses on the value measurement derived structure functions provide through interpretation of the heat flow path inside a package for use in thermal characterization, failure diagnosis, and improving simulation thermal model accuracy.

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
