Subproject 2: Building a Working Motor from Scratch
Currently, a few variants of the 8110 motor have been built.
V2 (Current, works) - utilizes NdFeB N38 magnets with 1.25mm airgap, tested KV of ~125.
V3 plans (in progress): Flux ring or CNC-machined rotor, and slightly thicker, N52 magnets, different winding counts
Some alternative/deprecated models:
V1: PETG, NdFeB N38 steel-epoxy-welded, Bad bearings, caused wobble/rotor would stick to one side of the stator core.
V1.1: Bearing problem fixed (no more wobble), however magnet rub present due to too small an airgap and epoxy buildup unaccounted for.
V1.2: Since the rotor was welded, I took this opportunity to print a 8010 PETG stator core, for a horrible, fully 3D printed motor (minus bearings and windings)
