brake units & brake resistors: dynamic braking for variable frequency drives & servo drives

brake units & brake resistors: dynamic braking for variable frequency drives & servo drives

braking units (brake choppers) are electrical switch. They limit the DC bus voltage by switching the braking energy to braking resistors where the braking energy is converted to heat.



braking units (brake choppers) are automatically activated when the actual DC bus voltage exceeds a specified level depending on the nominal voltage of…

Is Cleaning the Gyres a Pipe Dream?

In November, Design World Managing Editor Leslie Langnau, wrote a post regarding Ocean Cleanup, a mission to remove most of the plastic from the oceans. This plastic, which congregates in five areas, called gyres, is the result of millions of tons of plastic that is regularly dumped into our oceans. 

Boyan Slat, a young engineer and the pioneer behind the Ocean Cleanup efforts, believes that it can be done in only five years using a series of floating filtration platforms anchored to…
