Looks like it would definitely not be something you would want to be directly underneath. However, the air would not be blown directly downward, so you wouldn't sit under it when using it. Definitely a novelty for sure. Quote Link to comment Share on other sites More sharing options...

David Allen Posted August 14, 2022 Share Posted August 14, 2022 Glad to see it running but that brush arcing is terrifying! That is a serious problem and can ruin the motor. Quote Link to comment Share on other sites More sharing options...
Steve Stephens Posted August 14, 2022 Share Posted August 14, 2022 David, what is the cause of the brush arcing? And is ANY arcing bad or will a motor in good condition still give a little sparking? Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted August 14, 2022 Author Share Posted August 14, 2022 spring is weak. I only ran it for about 10 seconds. I will tune it up tomorrow. 1 Quote Link to comment Share on other sites More sharing options...

Some minor sparking is to be expected, but it should be minimal and only visible while you are looking directly at the brush to commutator interface.
