How To Connect Multi Wires AC Motor With A Capacitor Attached? 

Good luck next time!

Thanks & glad it helped 👍

Yes, certainly however the motor will turn the different way around. Cheers!

Thanks for the interested unfortunately I'm not a right guy you've asked. I think you can find some channel(s) regarding your concern. Good luck!

Thanks for the interested & yes, you've spotted one thing on! To put it in the simplest way for answering: The reasons for attaching a capacitor to a single phase AC motor are (1) Easy to start motor & then run it smoothly as you've mentioned. (2) To improve Power Factor because the coils inside AC motor as whole can be seen as an inductor in the AC circuit, so you might have known already - an inductor has the voltage 90 degree advanced over its current however a capacitor has the voltage 90 degree behind its current, in practical circuit a capacitor & a motor together will compensate some phase angles each other but all, that will be the result for improving Power Factor for whole grid system (for your own benefit, improving Power Factor, the less current goes through your home elec meter, the less the power bill you have to pay).

Thanks for your interested! You'd have known how to connect your 230v motor with four wires if you watched the whole video carefully. Anyway, some suggestions are here: make sure there is no Earth Wire among four wires. Name four wires as A, B, C & D. Using a multi meter ohm position to measure following two wires resistance such as A-B, A-C, A-D, B-C, B-D & C-D, then chosen highest resistance's two wire for connecting a capacitor. Connecting Neutral Wire (N) from the power to the one of wires from capacitor then connecting Live Wire (L) from the power to the one of the two wires left. That's it. P. S. -- So far three wires from the motor have been connected, last wire which has not been connected yet, that wire would be slow speed or high speed wire depending on Live Wire (L) connected to the wire was high or low speed. Also this conclusion supposed all group wires you measured, no zero value among them. Good luck. 🤜🤛

Connect one with another till it smokes, then your really done.

No, no, I'm sorry to hear that! If your motors are reasonably good condition, they should be okay for testing run so long as you followed the steps in the video or above. I'd reckon you'd mismatched or accidentally connected wires such as connected the power wires (L & N) to between low and high speed wires, this was one of the most likable reasons for smokes from motors because the value of impedance between low and high are much much lower than the value of impedance from normal operating coil for that motor. Good luck next time!
