Hai Dang

Dear Sir,

I got a question from a site supervisor that the power supply from a substation in a plan is 400V, but the motor is far from it. He uses a 400V motor, he's afraid that the voltage loss will not allow motor run well.

He requested supplier to change to motor 380V, but the supplier confirmed that there would be no problem with their proposed motor.

I think that 400V motor can run normally since motor also accepts to run with 5% voltage tolerance.

I'd like to have your advise on this case. Thank you for your intention.
