Today I used double 6 uF 400 VAC caps as run capacitor. This made a better result than 5x1.2 uF 400 Volt.

  • will the motor start with out the start cap

  • Every induction motor need a start cap on start up. It need very large energy to first run a motor. A start cap make it easy to run until reaching the running velocity.

  • bc i have a karcher deasl heated presure washer and it has 2 starter caps but the one craked and the stuff leaked out and the one i dont know if it will work still but i cant run it bc its winter and the new cap is 250$ and im am 13 years old so thats alot of money

  • That's good as a young as you interesting on this setup idea. But this is an energy saving setup that need to sure everything you used is good in normal/original setup before go to the next step in RV mode.

  • I can't hear the rpm changing, so it might be the same effect with all three different configurations! But did you put the cap in series or in parallell? I did not understand wich was most efficient..

  • My camera could not record the changing of RPM. The lower RPM is when the start cap disconnected and I got the most efficient setup is when start cap changed in position with the lowest Am drawing result (100 mA). The running caps connected parallel to input wires.

  • why i'm thirsty now?

  • I WOULD LIKE TO SEE THIS UNDER LOAD.. IF IT WORKS LIKE THAT UNDER A FULL LOAD , THEN YA GOT SOMETHING .. LOAD MAN LOAD .. MOTOR TEMP AND FLOW RATES ARE ALSO NEEDED .. JAY

  • @markoconroy It has to do with minimizing Reactive Power in the AC Power Supply. AC Current has Active Power (Watts), Reactive Power (VAr) and the Resultant Power (Apparent Power) (VA)

    Apparent Power = SQRT(Active Power^2 + Reactive Power^2)

    Power Factor cos(phi) = Active Power (W) / Apparent Power (VA)

  • Is the terminal board broken???

  • I need your help, thw writing in the video do you put in there. I need to make a video. Example is 1100ma .....in white. how do I do this. You video was good. Very informative/

  • @revizal you r great

  • I hate to point this out, but unless you are testing under load these results are useless. Also that motor sounds horrible, a motor should be nearly silent.

  • I'm not too bright! can someone explain this to me in english? how did the amps drop so much with no loss of rpm
