Hi,

What is the theory of eddy current brake used for reducing the AC frequencies 50/60?

There are tons of sand accumulating under and around belt conveyors carrying sand in the foundry plant where I'm working. We dump the sand back onto the belts using man power and it's gonna turn out to be a big deal every time when the belts were not up to the mark. So I wanna make a mini dredger wh

Hi design engineers.

What is the highest KVA can be obtained from the Flyback converter.

IDMT relays are mostly used for protective relays where A.C quantities are involved.These relays are used as overcurrent relays and sometimes as earth fault relay.

Such relays have metallic disc and the spindle of this disc consists of a moving contact which bridge two fixed contacts
