After review of several videos and electronic vehicles, I have some questions and may be you can help me with them.
For a long time I was thinking that Tesla produce the best electric motors for e-vehicles (AC Induction). Recently I found YASA motors (http://www.yasamotors.com/)
with incredible axial-flux motors. Below is a table that I created to compare Tesla motor vs. YASA motor:https://www.photobox.co.uk/my/photo/full?photo_id=9034110929
These numbers have raised important questions to me:
1) Is peak power density is the most important factor for EV electric motor?
2) I think that we should look at Peak Torque and Peak Power combination of factors. I mean the best electric motor is a motor with low Peak Power, which means low energy consumption, and high Peak Torque, which means strong driving characteristics.
3) As I understand, Voltage is also important because if we apply high voltage we will get higher Peak Power and as a result higher Peak Torque. The main problem is that high voltage controllers/invertors cost much more then low voltage (for example 350 VCD vs. 700 VCD).
So I will be glad if someone can validate my findings and comment factor is the most important to consider on electric motors for EV.
