Yes the stator wires get warm, hot even, and I advise that if you are a neat freak that you do not bundle the wires together tightly, doesn't matter if they are fused or not, leave some air circulation between them. They can get hot enough when bundled tightly to melt the insulation and then cause a short in the stator wires, and a fire.
This is written from experience.
BTW, when this happened, the wires were fused. It didn't blow the fuses, it just melted them.

From yet another Electrical Engineer in the group, let me pass on this bit of information
"Even our small stator windings can produce a short, high current pulse far in excess of its rating when dead shorted.
The stator is a 12-pole three-phase AC generator rated at
~25A continuous. In a three phase system the current in any
individual leg will be the rated current / 1.732 or square root of
three. This equates to a standard fuse size of 15 amps for fusing at
slightly more that 100% capacity."
OK, I don't understand what you mean by "two way street."

In retrospect, it's not a fuse that we need, it's a fusable link. Something that can take the pulses of higher current, while staying intact, and blow when the steady current exceeds a certain threshold.

I guess the only real way to find out exactly what it is doing at any given rpm is to check it with an oscilliscope that either has a printout or memory function.

Hizzo - you got such a device within reach?
