  I am an electronic engineer . I have more than 20 years experience in electronic and electric industry though have never stopped refreshing my knowledge in this field and in the other science . I want to tell you dear Jeremy that your approach to explaining the electromotors structure and functions are very useful for beginners and even for the experienced people .Thank you .

  I watched this video months ago, trying to learn all I could, not knowing how useful it would be for me. My mother wants a serger sewing machine and I found a very nice one local to me for a decent price with the caveat that in order to get the motor running, the handwheel needed to be turned. I knew that I remembered something from this video was relevant so I came back. I now believe I have isolated the issue down to being that capacitor or a starter winding and I haven&apos;t even seen the machine. Thank you for helping me make my mom happy!

  I loved that. Forget about flashy animations. Just a pen and paper and an actual motor. Brilliant explanation.

  I&apos;ve tried viewing other videos explaining this type motor but yours is the only one worth the time. &nbsp;You actually know how to communicate! &nbsp;A rare quality in the majority of youtube attempts! &nbsp;Thanks

  Jeremy, It astounds me there isn&apos;t this level of practical knowledge given to EE students. &nbsp;While I could spend hours telling you about the equations of magnetic flux, back EMF, torque, speed and estimated losses, nothing compares to this level of understanding. &nbsp;Power electronics needs to be taught very differently. &nbsp; I salute you for teaching this old electrical engineer something he missed all those years.

  6 years later and your video has helped me learn about the Single phase motor. &nbsp;Thanks for the breakdown and diagram. The details you point out makes a big difference for what to look for and understand.

  You have an exceptional gift for instruction. You&apos;re a good smooth, well-inflected speaker; soothing to listen to. Best of all though, you convey the sense of wonder necessary. My family always laughs at my preoccupation with these &quot;little&quot; elegances and ingenuities. If only they knew how such things make the world go round (yes, intended).

  Currently a grad student in Electrical engineering. I never realized that the dryer switch is what connects the start capacitor! That&apos;s genius! Also explains why when I don&apos;t press it long enough the dryer doesn&apos;t start up

  Mr. Fielding, your videos are exceptional...you have a gift for understanding technical things, and also to explain them. &nbsp;I started watching your videos about two weeks ago. &nbsp;I kind of understood that AC motors worked because of a rotating magnetic field, but didn&apos;t really understand. &nbsp;Thanks to your vid&apos;s and the old military training videos you linked, now I know so much better how they work. &nbsp;Fast forward to this weekend. &nbsp;My outside A/C unit quit working. &nbsp;It hums but the compressor/fan are not running. &nbsp;My first thought, thanks to what I learned from you, was this sounds like a capacitor problem. &nbsp;Sure enough, in my unit, the fan and compressor share a run capacitor. &nbsp;I tested it and it is definitely bad. &nbsp;So, 12 bucks on Amazon and a new capacitor is on the way. &nbsp;I am 99% sure this is the problem. &nbsp;But I would have had no idea if I had not watched your videos. &nbsp;Thank you!

  Superb Analysis...You guys wouldn&apos;t believe I&apos;m just seeing this,after 6years that the video got posted.

  Hi Jeremy my name is Mike, and I got into electronics about two years ago. Since that time I have constructed a full blown electronics lab in my basement, and also have been collecting motors and lcd/led displays. Until now I felt intimidated to break them out and try to power them (reverse engineer), as fear I would fry them. As it seems every tutorial elsewhere so far it seems he/she always leaves something out to where I abandon the motor project because it leaves that little &quot;well what if&quot; or just not confident of motor knowledge. But after watching all your videos, I&apos;m going down in to the lab and grabbing the meter and start banging out some pinouts.You definately have a gift of teaching and sharing your enthusiasm of motors, as I watched each video I sat there nodding my head, just as if I was there standing there in your shop...as I recognize all the motors, names, and most components of motors already, you banged the theory home and something clicked and I am pumped up!!! Thank you so much Jeremy, now is the hardest decision which motor to drag out from a collection of at least 60....take care and thanks again!! Mike.
