Imagine three magnetic poles alternating sequentially in a triangle or circle if you will. 3 phases 120' apart. Thats why 3 phase doesn't require a cap.

With single phase you need a capacitor to provide the time lag of the current in one of the windings. The other two windings just see the line current 180' apart from another.

t's actually a run capacitor. The function of the capacitor is to provide a time lag in the phasing to the run winding.

The capacitor is holding DC while charged.

@tstatech thank you I know I was worng on somethings but not sure now I know.

Is it still giving you resistance when the power is off

[67tr876]

@chrisbarbieri no I think I ran it so much that it seems to be back. but it still has some. I will give it back to you satrday.

What about box fan motors or other fan motors?

[67tr876]

@gatrwrks If they need it they use it. But that just go's for all 1 phase motors.

1 little thing. The capacitor is storing DC not AC and charged to a peak voltage.

hmmmm maybe thats whats wrong with my box fan.....

i love you that was clear as fuck

My old dryer that's in the garage right now has a bad start capacitor because when you try to start it all it will do is hum until you give the drum a push and then it works fine. Awesome video man!

Good explanation and demonstration. That might prevent someone from lighting their ass up!!☺

Good discharging idea ! I've never thought of that before.

[MrSciencetificsasuke]

thanks that was very helpful

I never thought about using a light to discharge a cap. I'm the type of guy that would just use a screwdriver to discharge it lol!
