I went to my EV Club meeting today in Tempe AZ. At the meeting this young m=
an told me about a motor adventure at his old school BGSU in 2002. Google:B=
GSU EDI FALCON ELECTRIC RACE CAR
He stated that a 10HP Lincon AC motor was converted to liquid cooling with =
transmission fluid. The internal rotor was immersed in the fluid requiring =
seals to be installed in a custom light weight case. =
=
He said the motor developed 100hp continuos but lost about 5% eff in the pr=
ocess. They used it at high RPMs and at higher voltages than the motor was =
spec'd for. When I googled the keywords above I found that the motor was no=
ted as 10times the specd HP at 145HP, giving the motor an original 14HP rat=
ing. =
=
Given that a vehicle requires at least 2-3lbs of vehicle for every lb of en=
gine/motor, and since a 145 HP continuous motor must weigh over 200lbs (I'm=
guessing) and a 14HP is mybe 65lbs, I'ld say that 500lbs less gross weight=
is worth the 5% loss. Since a lighter EVehicle saves some more for needing=
less battery storage, so much the better. =
=
I'ld have to add some estimate for the external fluid cooler and possible s=
econdary pump, but still sounds like a good tradeoff. BTW, the lighter moto=
r frame saves some weight as well.
=
What do you all think about the related issues of this modification? Will t=
he seals be reliable? How common are fluid cooled AC motors anyway?
