Within the realm
of both hybrid and purely electrified cars, there is a lot going on behind the
scenes, to say the least! Professor John Kelly of Weber State University took
the liberty of dissecting the block of a Bolt EV Traction motor apart for a
video presentation on the InsideEVs blog. Situated directly under
the hood of the car, this component contains the actual gears, electric motor,
and others needed to complete the all-important job of making the wheels turn.
As the blog
admits wholeheartedly, some people would think that this is the most boring
idea for a video ever, and that there are no gimmicks, car chases, or sight
gags. But there is an amazing quality about discovering how technology works,
and the WeberAuto YouTube channel has attracted over 100,000
viewers during its streaming days. Before starting the disassembly, Professor
Kelly discusses the motor and some of its performance parameters of the Spark
EV. When you get down to the actual nitty gritty of the Bolt EV motor, it
produces less torque and has a lower peak amperage draw, with an ultimately
higher RPM. However, it still offers more torque in the end, sporting a more
efficient design.
As you can see
for yourself in the video here, the professor then gives a completely guided
tour of the unit's exterior, explaining every single part seen from the outer
view. Once everything is labeled clearly, the deeper visual learning experience
gets started. All of us here at West Chevy of Knoxville marveled at the sight of the pipe where
the coolant comes in: there are six holes in the trough where fluid drips down
on various parts of the trans axle, in a very complex and precise arrangement.
The video provides fast-forward motion at just the right times when there are
lengthy turns and screws, and really does a great job of portraying the insides
and what goes on at every single instant of operation.
At about 45
minutes, you can really see the entire length of the rotor, and the task of
clearing the alignment dowel begins. The drip channel for the oil to come out
of the sump is pretty awesome to see close up, as well as the stator windings. Car
and Driver heaped on the praise for the 2019 model, citing impressive
range and immense practicality as two important reasons. We are beyond proud
that that same well-read publication deemed the Bolt EV as the “best everyday
electric car on the market today,” while being completely fascinated with its
powertrain and spacious cabin. As the future of the automotive realm promises
to change drastically, we are going to be witnessing full fleets begin to make
the switch and crossover; the Bolt remains the best specimen at this moment for
a sensational electric daily driver!
