5] Use the Registry Editor (

Click on the Start button and type “Regedit” from your keyboard.
Select the Registry Editor application from the best match.
If UAC prompts on the screen, click on the Yes button to give your permission.

calcul valoare condensator motor trifazic legat la monofazic

To connect our 380v tri motor in 220v mono (phase + neutral), we will use the triangle coupling.
We will connect for example: the phase in “u”, the neutral in “v”, and it will be necessary to add a capacitor between “v” and “w”
Very important !The capacitor must have a voltage greater than 230V and must be AC ??~, NEVER use a polarized capacitor otherwise it will explode!The usual value of the capacitor is expressed in micofarad “µf”
To find its value it is enough to multiply the power in CV by 50.
Example: a 250w motor (0.25kw)

to begin, you have to convert Watts into horses. for this we divide the watts by 736 (1 CV = 736 W)
In our example 250/736 = 0.34 HP, our engine is 0.34 HP.
To find the value of the capacitor: 0.34 x 50 = 17, so to operate the motor of 0.25kw requires a capacitor of 17 μf.
If the value of the capacitor is less than 17 μf, the motor will work much worse, or not at all.If the value is greater than 17 μf it is not annoying at all.

downgrade windows 7

Choose Run and write regedit.

Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

Change the keys EditionID and ProductName.

EditionID can be found in your Windows 7 installation CD under sources\ei.cfg.

ProductName will be shown when you try to install and are denied:

Windows 7 Ultimate cannot be upgraded to Windows 7 Home Premium

Here the Windows 7 Home Premium is the ProductName.

Make sure that it matches exactly.

This procedure worked like a charm for me!
