Traction Motor / Transaxle

Impact/EV1 development prototype - 102kW

===

This is an early version of what would become the EV1 traction motor  
and drive train as manufactured In August of 1992.  It is an  
induction type 3 phase Motor with a fixed gear reduction  
and differential.  

This specific motor / transaxle was either used in one of the early  
development Geo Storm platforms (1991/’92 time frame) or in the early PrEView  
development fleet platform  of 1992/’93).  

As noted development and testing of various EV1 subsystems was initially
conducted in a Geo Storm platform and included, but was not limited
to, friction/regen braking and propulsion systems development.  Dyno development
tests were  also run during this period out of the Castleton/Anderson
Indiana area where General Motors/Delphi had
development facilities.  

The next phase of EV1 development included the PrEView LPF (Limited
Production Fleet) of 1992/’93.  The PrEView LPF included ~50 hand built vehicles
that were used to gather customer feedback in various cities
throughout the United States (pictures are shown in our Impact prototype section
in the various time periods).  

The PrEView LPF fleet lead directly to the production EV1 in 1996, although
there were minor upgrades/changes to the motor assembly before
the EV1's initial release in December '95.  

To our knowledge all PrEView vehicles were destroyed, none were sold and  
none were donated.
