Motor: decided
Update 8/9/08
We traded in this boat anchor for this...
It arrived 8/8/08 viva Fedex
Update 5/7/08
We have decided to go with the NetGain Warp9.
"
The WarP 9" diameter series wound DC Motor has a double ended shaft and is similar to the ADC 9" motor, but with several improvements. Of the most notable changes is that the have a larger com bar and utilize the large GE style brushes.

Motor WarP 9" Up to 192 Volts Dbl 1.125" CE Shaft
The WarP 9" diameter series wound DC Motor has a double ended shaft and is similar to the ADC 9" motor, but with several improvements. Of the most notable changes is that the have a larger com bar and utilize the large GE style brushes.
The com bars are more securely attached to the arbor, so they are less likely to lift com bars. The drive shaft and tail shafts are bored for a pilot bearing and drilled & tapped for a 1/4-20 bolt, to mount tach sensors or secure couplers and accessories. They have duplicate ACD 9' mounting bolt patterns allowing use of preexisting mounting adapters.

1. DC motors are the least expensive but generally do not offer regenerative braking. Popular with the drag racing crowd.
2. Brushless DC, not many, info says they generate a lot of EMI noise.
3. AC motors seems to be the choice of the industry (Toyota, Ford, GM etc.). Best maintenance and efficiency. And of course the most expensive motors and controllers. Siemens seems to make the best, but it will cost you (>$10k) for a motor and controller. Azure(Solectria) seems the most affordable AC set up.

The motor decision may have been easier with a small light weight car. But the truck was available, <$1500, the body and chassis are in good shape, it can carry the weight of the batteries, and the conversion will take less chassis work (it will fit). There are many conversion kits on the market for S-10 pick-ups, they are just more expensive due to the weight of the truck. I would like to do an AC Motor, but time and money may point us to a DC motor like a Warp9 and a Curtis controller (Zilla controller would be nice but has long lead times). Here are some links to conversion kits.
