Drive Train Eff.

[Jeff Shanab <jshanab@earthlink.net>]

   I am playing with an idea for a design that would have a motor per
wheel but not in the hub. hub motors weight to much to have as unsprung
weight for the torqe we need. I also worry that eccessive vibration from
the road will wear out the windings' insulation and short out the stator
prematurly. They dip and bake stator windings in a varnish to minimise
abrasion wear on wires from the vibration created from varing flux and
current fields. I am thinking of 1 master controller and 4 slave
controllers to give it electronic differential, traction control,
anti-lock dynamic brakeing, and Bias adjustment for the traction and
braking.  I was hoping to make it look like those trick t-bucket
roadsters with inboard brakes and chrome half shafts. I think it would
add a positive image to EV's.  I have found some BLDC motors that can
put out 400lb.ft each would that be enough?
