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.

cheaper to replace the motor .
yes wes components
ph 02-97979866 heat transfer comp dries like hard rubber part code TSE3843W prise $38.50
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 :-)
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.
