A tiny three-phase motor invented by Swiss researchers could be used to power a new generation of wristwatches, allowing them to work as mobile phones, app devices and GPS units. Those activities generally require plenty of power, which can be cumbersome and costly — but a new microelectromechanical system will keep them juiced.
Researchers at the Swiss Federal Institute in Lausanne came up with a small electromagnetic three-phase motor that yields three times the energy output of a traditional motor.
While studying the weird behavior of high-temperature superconductors, scientists may have found a new phase of matter, separate from solid, liquid, gas and plasma. Electrons in a pre-superconducting state apparently form a strange, distinct order, lining up in a way that has never been seen before.
I recently moved my shop, and in addition to the big issues, from forklift rental to sleep deprivation, we also had to deal with things like three-phase power, a variation of power delivery often used for big equipment. The old shop had it and the new shop doesn't. So what the heck is three-phase power and how can you convert machinery to go from the more common single-phase to three-phase and vice versa? Read on.
