Anyone familiar with designing electric motors?
electromotive:
I'll put this idea out there, and see where it goes. I've wanted to take on an engineering project for quite some time. In particular, I want to engineer my own electric motor. I'm quite familiar with how motors work, but I'm unsure how to scale various components to target a specific output. For example, I'd like to build a 24V DC 1/2HP motor. That's all well and good, but motors have RPM ratings as well. For me this will likely be a multi-year project. I have no end goal in particular, just the satisfaction of having done it. Perhaps it could result in a way of producing a cost effective motor that could be powered by solar in developing countries for pumping wells. Who knows?
If anyone could recommend some good books on the topic, I would greatly appreciate it.

No big deal.
Your starting point is setting up a machine shop.
Lathe, mill, centerless grinder, stamping machine, furnace, surface treatment, heat treatment/hardening, precision measuring tools and a couple of other things.
Then you're ready to go.

Oh, and don't forget the account with the magnet, steel lamination, and wire vendors. Winding and assembling motors (Apart from the coil of wire and battery science class demonstration) is an activity that only works when there is a large scale business behind it. The investment is massive to even make one part. I suggest first visiting an industrial motor repair/rewinding shop. They are hard to get into sometimes, but I have seen a few. it will give you a sense of the scale of resources required.

These guys can get you started in something motor-related

I made a 3 phase ac induction motor in uni from 24V DC power supply. Fun project. I could be wrong but I think it is more electronics and less metalwork than other electric motors. Specially if you make your own vfd.
Nothing too challanging in it. Could save a lot of time if you think of easy way to wind it.
