120volt to 240volt

[Johnc]

Help! Can someone please advise on stepdown transformer requirements.
US 120volt 11.8Amp electric pump motor to run on 240 volt.
Thanks Johnc

I think you would need a 1500 Watt transformer. (120 V x 11,8 Amp=1416
Watt).

Since this is considerable motor it will need a good deal more capacity

to cope with the starting current than 1500 watts.
I do not know enough to calculate it but the first suggestion to replace
the motor would be best. Otherwise asking the question on
alt.engineering.electrical will get more knowledgeable answers.

Wot's Your Real Problem?

 

Just a note.. US power is delivered at 60Hz (110V), where many other
countries that use 220V is delivered at 50Hz. You may need additional
circuitry to convert the frequency, otherwise you motor may burn up
because it's not wound for the appropriate frequency.

Try 60Hz at 120VAC...hasn't been 110 since the late 60's

Try 60Hz at 120VAC...hasn't been 110 since the late 60's

And likewise UK AUS & NZ and others were 240 volts and Europe was 220

but all are now planned to to be 230volts 50hz

They just call it 230V +/- 5%, it's still 240 or 220 in many places.
