Unfortunately you cannot simply re-wire a 3-Phase 380V motor to run on regular 220V. 

The motor you have is probably designed for use with 3-phase 220V in "Y" configuration, which provides 380V. 3-Phase power is usually only available in factories and industrial settings. 

One possible option for home use is to get a rotary phase converter that turns regular 220V into 3-Phase, but that's actually quite expensive ($500 or more). 

It may be much cheaper to replace your current motor with a normal, modern servo motor that runs on 220V. 

Things are more complicated if the machine has a fancy controller with automation functions and pneumatic air cylinders (for back-tack, foot lift, reverse, thread trimming etc.)

By the way, posting to somebody's profile is not a private conversation. You can send direct messages that are private.

Hi thanks for answer, someone told me to use a capaciter,  and change the wires of the motor, sceme is inside, the machine has a pneumatic foot lifter, nothing else.

What do you think . Eventually what motor do you advice, which brand and type ?

thanks for reply
