There are Figures 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19 in the same text...

Ok, there must be some rule I’m missing, after which the penny will drop. Forgive my stupidity. How is the X1 (or U) junction defined...

So, what would lead you to point the X1 vector at the dot or non-dot end? It seems arbitrary.

Yes, you are right. That means X1 lags H1 by 30° in group 1, and X1 lags H1 by 330° in group 11. Both examples are correct. See Figure...

Thanks, so by that definition the group 1 will be a 30°, and the group 11 a 330°? There were two other examples: I make these group 7...

This is group 1. If H1 points at 12 o'clock, X1 will point at 1 o'clock. This is group 11. If H1 points at 12 o'clock, X1 will point at...

On behalf of someone on another forum; In both cases, he’s been given the answer, but doesn’t understand it: To me, the group does...

Without a wider range of experimental capacitors, I would use 20uF in that application. It is a case of balancing the inductive...

Results: Capacitance (uF):Current U:Current V:Current W: 013.413.18.3 1212.812.68.0 209.410.07.2 359.310.57.0 It looks...

Ok, well I have 30 uF and 20 uF coming, so that will give me the range 12-50 uF. Checking for motor voltage spikes, I assume my Fluke...

You understand the compensation requirements. I have not checked your calculations because your result is in the ballpark I expect...

An interesting short article on self-excitation in pf-corrected induction motors: https://nepsi.com/resource/Self-Excitation...

Moly oil is also available. I'm not sure if the moly will fit through the felt pads. It might depend on the particle size. BoB

I’ve had the motor apart for testing the windings and changing the bearings: It’s dual voltage, ie 230V delta or 400V star. Latter...

As soon as power is cut, the motor stops dead from the friction. Does that allay any fears? I’d guess that, at switch-off, we’ll be...
