Handcrafted

With so many simulation software's around to design motors, I wondered, what if i was lost in a jungle with a piece of paper, calculator and a book and had to design the fundamentals of a PMSM motor within two hours, failing which i would be lost in the jungle forever. A tad dramatic(Jumanji hangover-95 version). Could i do it, can i really slice the technology to its fundamentals. Well, i did try, it took a little more than a couple of hours, help of our intern(you can see the two handwritings, neater one is his of course), to try & boil down everything i have learnt into around 5 or 6 pages. By the end of it, the most pre-dominant feeling i had, was that of wonder, sounds cliché, maybe, but that's what would probably happen, when you realize true power lies in connecting simple fundamentals together in one form or the other to create a powerful output, could not get this feeling while simulating though. I am not saying simulation software's are a waste of money, they are highly essential to finalize and iterate amongst thousands of designs during the final run, also not claiming, if you read through what we've done, you can start full fledged manufacturing tomorrow, but it would definitely make something as complicated as "design and development of permanent magnet synchronous motor with minimal torque ripple and maximum efficiency" sound less intimidating and would probably push in a very small way to design your own electro-mechanical drives. You should be able to at least take a step forward to make a MVP or less. I have omitted few of the details, especially related to winding layout design, to invoke curiosity amongst the reader. Also, a basic understanding of a few of the material properties & constants would probably be a pre-requisite.
