Welcome

Disruptive Electric Motor Technology.  How? 

More EV range at higher speeds, especially trucks. 

Dura-Trac permanent-magnet electric motors key benefits:

  1. Optimize performance over a wide range of conditions.  Efficiency gains vs. motors using electronic field weakening to achieve higher rpm’s.  Link to more info, including white paper;
  2. Features can be retrofit to existing PM motors
  3. DFM to increase efficiency, lower cost
  4. Easy in-field service, extending service life

How does DuraTrac achieve greater efficiency at higher motor speeds? DuraTrac uses mechanical field weakening rather than electronic field weakening.

Motor Fully Engaged Like Any PM Motor
Motor Mechanically Shifted for Higher Speed and Increased Efficiency
Motor used in Cummins Hybrid-Electric Drive
