Parts Selection

Project information 2 Comments »

After reviewing various web sites in the links page, and researching motors, controllers adapters, chargers, etc., I settled on a package deal offered by Grassroots Electric Vehicles. The parts list is:

  • (The parts are in!)

War P 9″ Motor by Netgain

Listed as a 32 hp continuous, 100 hp peak motor.

IOTA DC to DC Converter 30amps

A30QS500-4 Safety Fuse

Xantrex e-meter

PCF- 20 battery charger

  • This charger will charge any battery from 12 volts to 156 volts from 120 volts ac input.

10 X 14″ 600V  2/00 gage Cables

I also ordered the adapter plate kit for my GMC Sonoma.

  • The adapter includes a motor hub to flywheel fitting which seems very hefty and a housing to fit around the flywheel and clutch assembly which is heavy gauge aluminum and nicely finished.

The Grassroots prices were better overall than other places I looked. Plus they have a shop in Fort Pierce, Fla, not far from Cocoa Beach.

The Warp9 series of motors seems to be the standard in use today. The controller, charger, and DC/DC converter were selections from a series of options, each with pros and cons but any would have worked. All parts are in.

The motor has a test setup recommendation to run the motor from a single 12 volt source to verify it survived shipping. I am setting up a fixture to hold the motor made from an old engine plate I have that is pretty sturdy.

I am also putting the other components on a board and plan to run the motor to test all components I can before installing the the truck. There are warnings against running these types of motors (Series Wound) without a load. So I am focusing on only short runs until I check out parts and connections. Then I will dismantle and install in truck.

Update: see video page for motor running with controller in garage,
