And the peak efficiency was estimated only from no load run data. For me this seems to be not accurate. Is the value of 88% not a bit too optimistic?
For example, for the last motor you have measured a static interphase resistance of 96mOhm and for etamax calculation you have considered a Ri of 100mOhm. This cannot be correct.
DriveCalc estimates the efficiency by processing no load and several load run data and it uses a so called dynamic resistance, which can be much greater than the static resistance.
