DC: danger alert?

The war between pro-AC fans and pro-DC fans has been around forever; ever since the end of the 19th century in fact.
Today, more than ever, the battle is raging! New technologies such as LED, cellphones, photovoltaic, and electric cars, are becoming more prevalent in our everyday lives, so it’s no surprise we’re witnessing a new major turning point in this AC versus DC battle: the pro-DC (electronic device manufacturer) fans are stepping up to the fight against the pro-AC (electric device manufacturers) who are carrying the flag for AC – which differentiates high and low current.

If either your industrial operations already use synchronous motors or if you are designing a new industrial process that could greatly benefit from the perks of a synchronous motor, probably you have given some thought about the guts of this type of motor.

Now let one of our fellow members of the community D.Ros tell you more about it. Enjoy!

Power losses in distribution lines: how to reduce them?

how to The electrical transmission and distribution losses accounts for most of the power losses in the entire system.

The largest amounts of these losses occur in the primary and secondary distribution lines, and can be classified as either technical losses or non technical losses.

With that being said, let A.N explain us everything about power losses and tell us how to reduce them. If you want to be published on this blog, send us a mail.

The renaissance of synchronous motor control strategies

Hi dears! Today D.Ros gives us the next article of his article series about motors. As usual, it is very interesting ; just judge by yourself:

Since electrical motors have been around, the cornerstone of heavy duty industrial operations (as crushers, grinders, mills, hoists, blowers, chippers, mixers, compressors, centrifugal pumps, exhausters, etc.) have been driven with synchronous motors for their high power and most efficient way to convert alternating current into mechanical energy; as for, different to asynchronous (induction) motors, their main source of magnetic field is derived from direct current injection rather than through the air-gap.
