First consider the speed of the vibration. If it is wheel or axle related it
will be a slow vibration. If it is driveline it will be three to four times
faster. In the realm of scary. To understand what slow is take the wheel

When I did mine I didn't have my lathe. Used my mill and rotary table and
did lots of passes, round and round. Is really smooth. Now I have a nice
lathe, could easily do an 8 inch chunk of aluminum. As far as the coupler,
taper locks are nice but instead I did a simple coupler, .0015 undersize.

Back to inverters. Be careful buying non UL Asian inverters. A lot of them
do not have a neutral to ground tie. You will find instead that the ground
prong or green wire is actually tied to the center tap of the output and
that NEUTRAL is 60

I would suspect that sunlight on the display raises the current draw of the
display. This current draw is on the 5 volt regulator of the entire meter.
Being an inexpensive meter the 5 volt regulator is also the reference
voltage for the meter. Current goes up, reference voltage goes down.
Ted,
I am not so sure it would be a commutator bar. If it were you should have
worn brushes down by now. My guess would be more like a winding broke loose
and as rpms increase it moves out to hit the field shoes. If it were me I
would disassemble the motor and pull out the armature. You will see
Hub motors are sprung, they are in the hub, which is sprung, as in sprung

To be simple it is not all about just the fact that all cells get the same

Thanks,
This is more than enough information. I like the idea of drilling and epoxy

Good point. It is very hard to hold onto metal above 70degC. I would bet the
max temp to be much higher than that. Also if you are concerned why not duct
air to it? In days way passed, we used 3" ducting on the cars we raced to
cool the brakes. It is very affective.

My Fiero project uses a BMW Z3 differential. IT is a 4.44:1 ratio. It is
very small. Might work?

Yes, $46,000 is a lot of money but don't forget about the savings in fuel
dollars over say 10 years or maybe 100,000 mles. Is it maybe $15,000.00.

You might consider changing the gear ratio. I am using a BMW diff that has a
4.44 to 1 ratio which is a little low also but I am using 2 9" motors in
series that will make things better. If I don't like it I am going to use a
Ford thunderbird diff which can be loaded with 5.13 to 1 gears.

I know it is cumbersome but we are still running our wave solder machine,

The problem with Hydrogen is that it is a pollutant. Until they learn to create
hydrogen from the sun, economically, it will stay a pollutant. Solar electric,
wind electric, and batteries, even if they still weigh too much, have
infrastructure, etc, they are not a pollutant.

I am building my EV around used Chevy volt batteries. To me it is a no
