The world is looking for a few more electric motor design engineers

Students, please listen up! Many of today’s electric motor designers are getting just a little bit OLD. (Never mind how I know.)

If you are mathematically inclined, like to draw, and think you might enjoy a career at the intersection of electrical, mechanical, software, and systems engineering, please consider studying the design of electric motors.

Link above is to a classic textbook in the field.

Lately I have been getting a lot of requests for leads, from recruiters looking for young talent that they all tell me is getting harder to find. I believe, as the best recruiters do, that demand in this field will be growing while materials and techniques for making better motors, better motor controls, and better electric storage devices are developed over the next few decades.

Lighter, cheaper, stronger, greener.

I’m going to find it somewhere for less than 190 dollars and spend my winter break reading it (:

For an old edition… that may or may not have full permission to be on the internet archives…

Edit: free account allows reading.

I was able to see the entire book my just making a free account.

found scanned version on zlib, seems to be roughly the right amount of pages but YMMV: Design of Brushless Permanent-magnet Machines | J. R. Hendershot, Timothy John Eastham Miller | download on Z-Library

Careful here…

There is a whole history of sketchy legal issues with Z-Library and the associated projects in terms of copyright infringement. Feel free to research it yourself, but they are currently shifting domains on a constant basis to try and avoid/subvert DCMA and Google restricting search access. Not sure on permissions for this book either.

Particularly the legal status section will give you a good scope of what all occurred in each jurisdiction. Alot of stuff in the US

as with any piracy-adjacent project, it will be completely encased in various copyright law nightmares. personally, i believe that if not for commercial use, books should be free, otherwise paid. but, unfortunately if this became the system overnight, our non-ideal world would immediately take advantage of it. hell, textbooks already run into the hundreds of dollars, which is ridiculous considering their sell volumes

so for now, for the full time student who would like to read into something they find interesting, it makes more sense to pirate a book then to spend $190 on it.

Engineering textbooks, especially those in specialized areas in which classes are offered infrequently, have been relatively expensive for a long time.

Inexpensive, unauthorized copies of such books have been produced in China and some other places for an equally long time. More recently it has been feasible to make them available by unauthorized electronic means — same idea for a new century.

One result has been fewer US students learning the less popular topics.

For the full time student it makes more sense to use interlibrary loan to access the book for free vs stealing it.

this makes sense, as a low demand for such an expensive-to-produce (not as in the literal book but the knowledge within). but,

this doesnt make sense to me. if anything, having easier access to textbooks would enable more students to learn these niche topics, because having $$$ is no longer a barrier to entry.

hmm, but with a library you can run into issues like the number of books available, having to return and borrow again, etc. but sometimes it is worth the time spent to get the physical copy of a book.

this can also be a matter of preference. i just think its easier to load my calculus textbook in sioyek and view fullscreen, rather than use a free physical copy that my teacher lets us borrow for the year.

@Richard_Wallace How does Design of Brushless Permanent-Magnet Machines: J.R. Hendershot & T.J.E. Miller: 9780984068708: Amazon.com: Books compare to Brushless Permanent-Magnet Motor Design: Hanselman, Duane C.: 9780070260252: Amazon.com: Books? I took classes with the author of the second book.

It has been a while, but the last time I used ILL they just sent me digital copies. And there wasn’t a return/recheck requirement. YMMV

Prof. Hanselman’s text is very good. Another good one is by Kenjo and Nagamori (1984). Prof. Kenjo began as a motor engineer for TEAC tape recorders in 1964. A couple of years later, Nagamori became Kenjo’s first student. Nagamori founded Nidec and still serves as its CEO.

as in the people who make the best brushless motor for frc!
