Webinar with subtitles in multilingual:
"Brush up on Motor Design!" Vol.72 has been released!
"Brush up on Motor Design!" by Prof. Miller, an authority on motor design is available on our website.
From beginners in motor design to experts in design and analysis, this content can be of reference to everyone.
The following webinars have been published this month.
You can view it not only in English but also in many languages!
[Vol.072] Operating characteristics
The 72nd seminar takes a deeper look at the operating characteristics of synchronous machines, systematically explaining the output-load angle characteristics, V-curves, and MVA charts (power capability curves) that define the operating limits.
Drawing on classical phasor‑diagram‑based analysis, the video also discusses the use of the finite element method (FEM) to account for nonlinear magnetic saturation. It further covers a range of theories indispensable for practical operation, including the effects of saliency, steady-state stability concepts, transmission characteristics, and the Ferranti effect.
By bridging theory and real-world practice, this seminar provides essential foundations for designers and analysts seeking a clear understanding of stability margins in synchronous machine design and excitation control behavior during power system interconnection.
In addition, we have published columns on various themes.
We recommend first taking a look at "An engineer's diary".
