Swapped motors in the EV Hilux and with the motor out of the EV Hilux, we have done some initial testing for suitability &/or feasability for use in small aircraft.
While the test was exciting, it also was dissapointing. The motor could only reach 1500rpm, 2000 needed. The motor could only draw 220A. The rpm too low to allow more amp flow. Batteries were at 150v. This test used the standard propellar normally used on the aircraft. The pulling force only reached 92kg, just over half of the Subaru EA81 engine with a 2.5:1 reduction drive.
This motor would be good if we used a reduction drive, but we were hoping that we could do it direct drive. We changed the pitch of the propellar with some increase in pulling power. The next test will be with a shorter prop, smaller diameter.
