Short Circuit Diode

I had short circuit diode in the IGBT on the output side.

New IGBT, working..!

Broken Negative Controller Terminal

eViking: Let's Wait fast: Converting an ATV to electric is a very tricky thing. Solving one problem will cause three new ones. I started to work on a smaller version ...

Twist And Shout

I am using a shunt and a JLD404 to see my consumption.

The problem is sometimes a much too high number.

Mostly when I work with the ATV as a camera car.

A lot of stopping, starting, reversing and again..

First I had my cables twisted. And very bad numbers.

Than I untwisted my about 1,8m cables for a 88Km range test drive. The numbers came closer.

But not at filming.

Now I have a new twisted and shielded and frame grounded cable.

And..same problem.

I guess it has something to do with the direct drive and the controller.

Back Electromotive Force and a stalled motor when starting from zero could probably cause this problem..

Upside Down

I lost two Meanwell DC/DC converters this year.

Moisture accumulates between housing, insulation and electronics board

and destroys the board.

  

Simple solution is mount the converter upside down.

Pre Thinking

It is not particularly easy and cheap to build a simple test version.

The exact position for the second bearing on the larger gear wheel is the problem.

I think, I can go directly to version 2.1 milled out of aluminum...

Drive Shaft Measurement

First I need to know how they made the original drive shaft.

 Second: Thinking about the most perfect test drive shaft.

Drivetrain 2.0

The first parts for the new drivetrain just came in.

So what is the plan..
 I will test a 2:1 drivetrain with industrial components.
When everything works out, I will make the parts lighter and possibly fabricated new parts out of 7075 aluminum.
We will see.

The eGrizzly was doing a perfect job in a project I can't talk about.

Of course with no exhausts.
