Question 1: demonstration

Based on five measurements of the resistance, obtained using the schema in the Figure 2, their average is computed.

Figure 2

Stator phase resistance was computed taking into account the stator connection (Y), respectively

,

because the current Id flows through two phases series connected.

If the stator would be connected in triangle (D), the phase resistance would be computed using

,

because the currentId flows through the circuit composed of one phase, in parallel with the other two in series.
