The Latch holds the back in place. You

The 12 Volt Power Jack
is where you plug in 12 volt power from the AC adapter
(included) or the
automobile 12 volt power cord (also included). You can also run the miniSpinner
from a portable battery pack. Because the miniSpinner
uses so little power, a small portable jump-start battery will run
it all day.
That black finned thingy is a Heat Sink that
conducts heat away from the motor, which is directly beneath it. The flyer acts like a fan to blow air
across the heat sink, cooling the motor very effectively. The
heat sink probably isn't really necessary; early prototypes didn't
have one and the motor rarely even got warm. But, better to be
conservative, so the production miniSpinners have heat
The Motor Sheave (whorl to
spinning-wheel types) drives the polyurethane
belt that drives the flyer.
You can also see the
large shielded ball bearing at the orifice (right) end of the flyer.
The bobbin (left) end of the flyer runs in a self-aligning plastic bearing
for the minimum amount of friction.
does not need oiling as the plastic bearing is self-lubricating, and
the ball bearing is lubricated for life.
