Hello there, I have discovered EV and this site over the last week and I am bougth by it!!, I have been reading a lot and still I have lots of doubts, on top of them is the motor type you have to use for your EV. I understand that you have the following types of motors for EV:
DC (Sepex, Shunted, Permanent Magnet)
AC
Why will you use one or the other?, most projects that I have seem use DC shunted motors and in small vehicles PM is the most prevalent type.
Why AC is not the preferred type?
I understand that AC has cero mantenaince but smaller efficiency but I wonder what are the main factors, technically and money wise, to select a particular motor technology for an EV.
Thanks for sharing your tougths.
