The values in the spreadsheet look generally reasonable, except for the completely nonsensical torque value. I can only guess that the cell in the spreadsheet which calculates torque has been accidentally modified.Done some preliminary calculations to find values for PMAC Electric motor which can go with Curtis 1234SE 5471.
I am going with two independent rear wheel motor setup, for a small 1500Kg Hatchback, doe values like 15KW. [email protected] per motor make any sense?
torque = power / rotational speed
torque [Nm] = power [W] / (speed [rev/second] * 2 * pi)
For 15 kW @ 1500 RPM, torque is about 100 Nm, not 2 Nm.
I'll also note that the spreadsheet calculates how much power is required to keep the vehicle moving at 120 km/h... but allows no extra to accelerate so it can get there.
