I gather its an empirical rule.

The nameplate rating is the max. per winding, which is also the nominal current
for full rated torque. But, an 8-wire motor complicates the situation.
The nameplate rating is for unipolar or bipolar series connection.
You double the current when using the windings in parallel.

Yes.
