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”.

Follow the history of Alltrax and PCE as the leader in Performance Electric Motor Controllers.

  • 1996; Located in Bellingham Washington (USA), Mr. Crockett formed DCP focus on providing the EV Racing market with an counterparts. (Including the tire smoking Sparrow shown at upper right)
  • 2000; Moved the company from Bellingham Washington to Grants Pass Oregon and formed the Alltrax (2001) and PCE (2005) companies.
  • Alltrax Inc – Manufacturing, Sales, Marketing, Accounting
  • PCE – Power Control Engineering and controlling intellectual capital and intellectual property.
  • 2004; JIT-TQM Launched Just-In-Time (JIT), Lean Western manufacturing, and tools from Total Quality Management Processes (TQM).  These Methods reduce lead times, reduce waste, and instill top quality control into our staff.
  • 2006; OEM Instituted Original Equipment Manufacturing (OEM) 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; System Components such as solenoids, diodes, pre-charge resistors, and heat sink assemblies to make your purchases easier.
  • 2009; SPM 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.
  • 2015; XCTSHUNT Regenerative Advanced Motor Controller.  This new platform with 4 year development changes everything:  Internal heatsink, 32 bit microprocessor, USB 2.0
    programming, 4x or 2x mounting bolt pattern similar to industry standards, easy installation, Dedicated connectors (no adapters!), Optional Hi-Reliability serviceable Fan for 300-400amp models, Fan included on 500amp models, 300 through 500amp 36-48V models. Case is ABS+PC510 Thermal Plastic with 94V0 and 5VA flame rating. Epoxy filled for any
    environment. All Copper heatsinks.
  • 2016; SR – SERIES Advanced Motor Controller. Leveraging from the design of the XCT platform, the SPM was ported into the new physical shape as the XCT. The SR uses the latest high powered and high efficiency MOSFETS to provide awesome power and performance in a industry standard footprint.  With USB programmability and user input personality switch is a cost effective power house. Dedicated color coded user cconnectors (no adapters!), Optional Hi-Reliability serviceable Fan for 300-400amp models, Fan included on 500-600amp models. SR 300 through 600amp 36-48V models with SR 300 through 500amp 72 Volt models. Case is ABS+PC510 Thermal Plastic with 94V0 and 5VA flame rating. Epoxy filled for any environment. All Copper heatsinks.
  • 2016; FN Control boxes. The XCT and SR have user inputs for the customer to select a profile, adjust speed, or adjust regen (XCT) while driving the vehicle allowing for mild to wild
    performance selection from the front seat.
