DuraTrac shifting motor is ideal for multi-copters, designs with vectored thrust and designs using independent motors for lift and cruise.
Need more speed or range of your eVTOL aircraft?
At the eVTOL Technical Meeting, 01/29-31/2019, Lawrence P. Zepp, Chief Technology Officer and co-inventor, DuraTrac motor, presented information how Dura-Trac technology can increase cruise speed and range of eVTOL craft. PDF’s of information presented:
- Overview describing DuraTrac technology and why it increases cruise speed and extends range L.Zepp_eVTOL_Presentation_Final
- Paper providing more detail about issues associated with field weakening and why DuraTrac mechanical field-weakening is better approach. LZepp_eVTOL_Paper_Final
- More about conference for reference Autonomous Vertical Technical Mtg 01_2019)
DuraTrac will be glad to discuss in more detail the technology and steps to implement. Best first step is email Larry Zepp at larryzepp2@gmail.com.
