I am new to the club. I am VERY happy to know that you guys exist. Also I am
very unhappy that Opec and car companies insist on making shity high
maintenance gas cars.
I have had a question about gear boxes and transmissions for a long time. I
have read on one site that in converting a gas to an electric you need to
leave the 5 speed (or what ever it is) transmission in the car to be used
with the electric motor.
I understand that electric motors have full power the second the shaft turns
and all the way up to max. RPMs (10,000 rpms). I know that gas engines only
have power between 1000 - 3,500 rpms. It is obvious that gas motors need a
transmission. But right now I am under the impression that electric motors
don't need a transmission. I think trains have a motor built right on to the
axle. If an electric motor can break that kind of static friction to move a
freaken train with out a trani then why would you need a trani for a car.
The diesel motor on the train powers a generator,.... I have heard that the
trani used in the EV1 & RAV4-ev was a "single speed reduction integrated
with the motor and differential, to help with torque. I have also read that
the Owen Magnetic made a car, before the depression, moved by an electric
motor that did not have a trani. It was sold to rich people. Some electric
motor companies will sell gear down boxes with their motors. To not have a
trani in the car would mean WAY less friction losses and less
My question is do you need a trani for an electric car or not. Are my facts
straight,... I am ready to be educated. Thanks for your time folks.
