D.Ros is so crazy about motors that everytime we receive an article from him, we know what it’ll be about. Despite of this, his material is always very interesting and well explained.

For our pleasure, here’s the latest article from him. He chose to make an insight to typical start-up profiles… Let’s read!

Understanding the basics of how synchronous motors work will surely help you take good decisions upon whether or not to use this type of motor, if you rather get a brushless exciter or not, and choose the right start-up method suitable for your application and power system’s availability.

The next thing you should get to know is how a typical start-up looks like, what problems you might encounter and what are the possible solutions to them.

Last day, D.Ros told us about brushless synchronous motor field exciters. Today, he focuses on motor start-up strategies. Enjoy and ask questions if you have any!

As time goes by and industries keep growing and growing exponentially, motors keep getting larger and sites keep moving further away from the power sources, however, most of the times, power systems can’t keep up with the voracious rhythm of industrial growth.

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!

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.

Last time, D. Ros published a very interesting article about motors and drives. Today he’s at it again with synchronous motors and guess what? He proposed to publish a series of articles about motors! We thank him dearly.

Synchronous machines are highly regarded in the industry for their unique applications of high mechanical power demand, power system control, and plant power factor correction.

However, the uniqueness of these applications has lead into different regulation techniques oriented to meet their specific requirements.
