content: I'm looking for something that will give me a good comprehensive overview of all the different motor types, how to wind them, detailed but basic explanations into how they function, etc. I don't have a good understanding of electric motors -- there's still too many knowledge gaps I'd like to fill in. Usually I just watch youtube videos or read forums, and the problem is I get pieces of scattered information but never the full overview.It would be cool if the book has information about modern cutting edge motor technologies like teslas EV motor, but not required.

content: Not exactly a book but for anyone who knows naff all about AC motors but wants to learn a bit this is a pretty good 70 odd page PDFIt’s written around submersible bore pumps but the knowledge is applicable elsewhere.Particularly useful but oddball sections relate to figuring out which wire is which for wiring up a motor using a multimeter and sizing of motors vs generatorshttps://franklin-electric.com.au/aim-manual.aspxFull PDF if you’re more into that is the first link on the page (full aim manual) otherwise being broken into topics is handy

content: Quote from: tepalia02 on May 21, 2022, 02:56:19 amI found the PDF for free on a university site and gave it a look over. Its overly-technical for my needs, it's written for very advanced readers who have a university degree in EE I think.I'm looking for a 100% motor specific book, I found some but not sure if they're good or not:Permanent-Magnet & Brushless DC Motors by Kenjo & NagamoriElectric Motors and Drives: Fundamentals, Types and Application by Austin HughesUgly's Electric Motors and Controls, 2020 EditionElectric Motors and Control Techniques by Gottlieb, IrvingHow Do Electric Motors Work?

content: Rebonjour, the Audel's books were started in the 1930s, Automotive, engines, motors, etc.All are thick handbooks, very practical and written for the repairman, user, or technicians.Lots of tips and simple explanations.I had my first Audels in 1950s!Jon

content: Quote from: jonpaul on May 21, 2022, 04:16:44 pmYea those Audel books look great! There's something special about those old books -- they seem to offer really simplified and clear explanations. I love the hand drawn illustrations too

content: As a child in 1950s, I discovered the Audels Automotive manual.The engine diagrams and ignition system figures fascinated me.I believe that book influenced me to do electronics, and became an electrical engineer.Audel's books are everything practical and the underlying theory explained in very easy to digest manner.Jon

content: I'll share details on the best books I was able to get a look into.Mechanical Design of Electric Motors by Wei TongThis book seems to be the most comprehensive resource out of all of them. Nice clear language, very technical breakdowns, excellent illustrations and you'll never find a full page of math calculations. It's complex but doesn't seem fully out of reach or intimidating compared to other books.Wei Tong is a genius - how does one man know so much about a topic.. it never ends, look at this:ContentsPreface... xxiAuthor... xxvList of Symbols ... xxvii1.

content: electromateria, can you detail what specifically about motors you're hoping to learn, and towards what application? Learnign is usually easier when one is trying to answer a specific question one has, or find out enough to solve a specific problem or plan out a specific future idea.

content: Quote from: Infraviolet on May 23, 2022, 09:03:55 amIn the short term I'd like to learn about motors I can use for EV projects (mainly interested in brushed / brushless DC / outrunner. I also use 120v AC motors for equipment / custom machinery, eventually I'll be using 3 phase motors. Very interested in linear motor systems as well. I feel I need a broad overview of everything.This really interests me:https://www.freerchobby.cc/products/mp20280-45kw-95kg-thrust-brushless-motor-for-home-build-flying-carMy short term goal is to wind some very primitive, poorly engineered, medium sized DC motors to gain some experience. In the years to come I'll be building out a machine shop. Once I get a rotary converter, large metal lathe, milling machine etc I'll be able to try to build a well designed, extremely powerful motor like the one above (assuming I can gain enough comprehension).

content: Quote from: jonpaul on May 23, 2022, 08:13:49 pmFor residential this is a non-starter in most of the world, it simply isn't available to houses. It doesn't really matter though, VFDs are inexpensive and very versatile, even at my friend's shop where they have 3 phase power, almost all of the machines have VFDs for the features they provide. Variable speed, soft starting and smooth reversing, etc.

content: There is a good book about circuits surrounding motors and some facts and details given about how the motor and controls interact. The book is called 'Electric motor controls 7th edition'. It was the go-to book in my 4th year electrician journeyman class here in the states. If you want to look into something that takes a lot of understanding look at an A.C. traction G.E. locomotive. The motors have a very heavy welded bar squirrel cage rotor with a three phase stator. I forget how many poles the stator has. The motors generate no output from residual magnetism but yet can produce several hundred volts at a few hundred amps each (X6) to back feed several air cooled dynamic brake grid resistors connected across the link voltage rails. The grid blowers are D.C., the higher the link voltage the faster the blowers run. Doubling the link voltage quadruples the power going to the blower motors.

content: Quote from: jonpaul on May 24, 2022, 01:02:52 pmOur industrial machines usually have 3 phase motors but residential stuff is all single phase. Some residential situations like large farms have 3 phase power but generally speaking it is not offered to houses, you might have all three phases running down the street but individual clusters of houses will be staggered on just one of them.I know there are a few parts of the world where residential 3 phase is the norm but they are the exception, not the rule.
