Parts Selection

Project information Add 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.

Logi144AFX 750amp Controller by Logisystems

  • A solid state motor controller working up to 144 volts and 750 amps

Emergency disconnect

EV200 Contactor

PB-6 Pot Box Accelerator

  • Uses a 5000 ohm potentiometer (variable resistor) to direct the controller to deliver current to the motor

throttle-sm

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,

    Hi,

    nice project, i was wondering if you ever finished the project or is it still in progress?

    is the throttle potentiometer double ganged? it is a lot safer if you use a dual pot, in case one of the throttle potentiometers fails.

    regards,
    John

    The pot is a single unit. Double ganging is a good idea but increases the risk of one pot shorting and taking the whole unit out. But this is a less likely failure than the pot going open circuit. The throttle unit has a safety switch which closes when released and I have added that to the circuit to clamp the unit to zero ohms in case the pot opens, which would mean full throttle-a bad failure mode.
    Thanks for the comment. Sorry I took so long to respond.
