The History of Alltrax Electric
Vehicle Motor Controllers
The Electric Vehicle:
As the threat of world stability drives oil prices higher,
consumers and enthusiasts are looking into
alternative drive systems, taking control of their
energy consumption, but still want the performance
expected from the hydrocarbon engine counterparts.

The Company Founder:
The company founders, Damon Crockett (a power
electronics engineer of 26 years from Klamath Falls
Oregon) and Jeff Bradley developed high power motor
controllers for electric racing vehicles.  

A few of these powerful
Electric Race cars had the
capability of dumping
750,000 watts of power into
two motors during an
8 second 1/4 mile run down
the race track.  Obviously requires controllers that can
"handle the extremes".

Performance Electric Motor Controllers.

    Services and After Market Services (AMS) by helping the EV
    industry design, build, and manufacture their products using our
    expertise and collaborative team resources.
  • 2008; Adding System Components such as solenoids, diodes,
    pre-charge resistors, and heat sink assemblies to make your
    purchases easier.
  • 2009; Easy to install Digital Speedometer for small electric
    vehicles, golf carts, Low Speed Vehicles (LSV), and  
    Neighborhood Electric Vehicles (NEV) to comply with state laws
    requiring speed and stored Odometer.


  • 2011; SPM - Series Permanent Magnet Advanced Motor
    Controller.  This new platform changes everything:  Internal
    heatsink, 32 bit microprocessor, USB 2.0 programming, Color
    Coded Terminals for easy installation, Dual E-Z-Go connector (5-
    pin and 4-spades), Hi-Reliability serviceable Fan, 200 through
    800amp Heavy Duty.



  • 2011; EXRAY-VOLT - The Speedometer with VOLTAGE reading is
    an upgraded version of the EXRAY Speedometer.  The new
    battery pack voltage reading works with for 12, 24, 36, and
    48volt systems.  The EXRAY-VOLT plugs into the exact
    connections and brackets as the EXRAY so a great upgrade for
    existing carts.  Works on Gas carts monitoring alternator and
