Hoverboard motor output questions

[GreenTeam]

I put my little 4.5"er on a meter and gave it a little slaps. Lol. And I noticed that the thing has very low cogging compared to the 6.5" motors. Also, it really got harder to turn when I set my multimeter to the 10amp circuit. Can anyone fill me in as why that happened?

more current you try to draw the harder any PM generator will turn.

   Try to spin-up the shaft with a drill and see how long it takes to blow the fuse in your multi-meter.

This is related to "cut-in speed" on small windmills generally this is building resistance/impedance in to the stator. A dead short will make it impossible start in low winds. With machines that have "power in watts" of a large capacity it was talked about using a "carbon pile" in series with the load that can allow big power draw yet free-wheel if desired. Also this has its drawbacks such as over-speed conditions that can destroy a mill. Furling comes to mind but is not electrical but can regulate output.

Blow my multimeter!!! I cant do that lol. I am operating on a very small budget. Let's say that my budget is so tight that I am extending enameled wires by carefully soldering lengths to extend them , and than paint with clear nail polish to make sure that there is no arc after to short out my coil.

GreenTeam;
At this point it might be a good idea to spend sometime looking at the FAQs instead of waiting for someone to answer your questions only for you to ask another.
99.99% of the questions you are asking have already been asked and answered.
While not sure if a hoverboard motor has been asked about before, but the questions you're currently asking have already been asked.

Thanks for understanding

PS>>> this could not only save you time , but $$$ in the long run (that includes NOT blowing up your meter  )

The Fieldlines FAQ's are good, but even better (especially when used together) is this: https://www.allaboutcircuits.com/textbook/

Thanks for posting that, here at work even those very useful sites are blocked  .

Thank you! And I understand what your all saying. But , I learn quite differantly. And I often do not have confidence in what I read unless someone confirms it for me. Been a hindrence all my life in school. And sometimes I got Into paralysis through overanalysis .
