What is your spec. KW motor and Capacitor
It even possible to recharge a system through high head pressure? I'm just curious to ask.
Yes... it okay to charge in liquid into the high side but the if the high side pressure is higher than the refrigerant cylinder pressure, the recharging won't be possible as the high side pressure would tend to push the ingoing refrigerant back. It better to charge from the high side if the compressor isn't running. Then, the high side pressure would be lower. Thanks
Please watch the video I made earlier about how to Identify wires meant for capacitor in a single phase motor. The video can help you avoid pump damage if you mix-up the wires mistakenly.
You are most welcome friends.
Great video!
Many thanks. Would you like to watch my other video on how to identify wires meant for capacitor in a motor? Its a great video and such information is really rare.
@@JeremiahThomas-qr4on Gladly.Thank you!
If load given motor will stop or heat
Please repeat the question sir
My question is that can we give full load or what bcz I tried this but my motor heat up and if load is given means my motor stops by force of hand
It depends on your motor capacity and the capacitor used. The motor rating goes with capacitor sizing as well.
You should give 1/3 of the rated motor load
Load given should depend on motor rating please. If too much load is given to a motor of lower rating, it will definitely overload the motor
Did you include neutral? Does motor use neutral?
Yes please. Neutral and life(phase)
Motor is there phase motor but we are running it with single phase power(life n neutral).
What capasitor i need uf...3 phase motor to single phase 220v Motor specs... Ydelta. 346-480/220v 1.40/2.45 A Cos♤ 0.84 0.55kw. 3400. 1/min. 60hz
Pls use 7.5uf capacitor. Sorry for the belated reply. I was away for a while.
will the motor not reduce energy and fail to pull
One third of the power would be derived
Though it would run more efficiently.
Thanks Jerry

What the design voltage for this 3 phase motor ( 220v or 415v) regards
415v(3phase). I am using 220v(single phase) to run it instead.
415v sir. Sorry for my belated reply pls. I was away for sometime.
Excellent
How to choose capacitor size depending on motor size as well! For example for 1hp motor what mfd of capacitor should be used? Thanks
Greetings sir. Please use 10uf for a hp. 20uf for 2hp, ect.
How many Uf sir
Depends on the motor kw/hp sir
Use 10uf per hp motor. 20uf for 2hp ect
So nice thanks
Many thanks to you as well.
I wish you could explain in terms of u,v,w how you connect the capacitors
For example u, terminal of the motor connected with blue wire of the capacitor and short the red,
Greetings sir. I used w2 and v1 for the the power lines. U2 and w2 for the capacitor.
You may chose to use any of the terminals after changing the motor to Delta configuration. All you. have to do is the fix the two power lines on any of the 3 terminals(u2 v2 w2) then fix one wire from the capacitor on the last/empty terminal, take the remaining capacitor wire to any of the power cables.
Can you chat me up on WhatsApp so that I understand what you mean perfectly. +234-9065697879
A simple connection diagram would have been more easy to understand.
How can i know the size of capacitor for the Different sizes of motor bu kw or hp and what is the biggest size of motor can run single phase please let me know thanks 👍
Greetings to you. Please use 10uf for a hp. 20uf for 2hp, ect. You could run motor of any size depending if your power source can feed the current drag comfortably. Your power cable also matter, pls use cables that matches the motor's current requirement. Thanks 👍
Nice one
Thanks brother..
