La capacité en μF du condensateur doit correspondre exactement à celle requise pour la conversion du moteur de 380V en 220V. La tension du condensateur doit également être la même que celle nécessaire pour le bon fonctionnement dans la durée.
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"
How to choose capacitors for three-phase motor, using it in 220V. The capacity of the starter capacitor. The peculiarities of selection of capacitors. Reverse. Sometimes that falls into the hands of three-phase motor. It is from these engines made homemade circular saws, emery machines, and various grinders.
要将380v转换为220v电,可以按照以下步骤操作：首先,通过配电柜,将三相四线中的零线分离出来。从三相四线漏保开关的下端引出三根线,连接到一个分3p开关的上端,作为电机的电源开关。这样,
Choisir le bon condensateur pour convertir un moteur de 380V en 220V nécessite de suivre une formule précise basée sur l''intensité indiquée sur la plaque signalétique du moteur triphasé. Pour un couplage triangle en 230V, il faut multiplier l''intensité par 13,8466 ou la diviser par 0,07222 pour obtenir la capacité nécessaire du

Picture 1 shows the data plate of a 370Watts PFAFF clutch motor which can be run on 220V and 380V; Picture 2 shows the original 380V setup of this motor; Picture 3 shows the setup of the same type motor
You might be able to find a VFD with a built-in voltage boost circuit to give 380 volt, three-phase output with 220 volt, single-phase input. Otherwise you would need an input transformer for the VFD and a 380 volt VFD that accepts single-phase input. I don''t know what all the options are with a Steinmetz connection.
3-phase autotransformer uses copper or aluminum winding, rated capacity 75 kVA, steps down the primary voltage 380V to secondary 220/200V, frequency 50/60 Hz, self-cooling or wind-cooled.

Converting a 380V motor to 220V is not a simple task and requires professional techniques and tools. First, you need to understand the internal structure and...
Utilisation d''un condensateur pour passer d''un moteur 380V à 220V. Convient surtout aux moteurs triphasés de petite puissance. Faire démarrer le moteur en étoile-triangle si compatible. Utiliser un condensateur permanent pour stabiliser la tension. Calculer la valeur du condensateur pour un fonctionnement optimal.
You might be able to find a VFD with a built-in voltage boost circuit to give 380 volt, three-phase output with 220 volt, single-phase input. Otherwise you
How to chose the correct capacitor: rule of thumb: capacitor = 60µF to 80µF per KW. Assuming the Motor has 370 Watts = 0,370 Kilowatts (KW) 0,370 x 60 = 22.2 µF. 0,370 x 70 = 25.9 µF. 0,370 x 80 = 29.6 µF. So capacitors between 22µF and 30µF will work. I always choose a 25µF capacitor as it is just in the middle and works fine.
