Here are some of the guts. I'm breaking the posts up to make discussion easier.
I'll start with the stator. It's part of the middle section of the assembly.
Here's a closup of the stator slots and windings. There are 48 slots. The stator OD is 235mm, and the ID is 150mm. The slot width is 45mm.
Here's a closup showing some of the winding details. The winding wire diameter (including varnish) is 0.030", close to AWG #21. There are three wire groups/phase; I think there are 12 wires/phase.
