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.
