Normally the motor will say 220 Volts as well as 415 Volts(or close voltages) on the rating plate, even if the plate says 415 Volts only its worth removing the cover ofer the motors terminals, if you see 6 terminals and 3 are connected together OR you have 4 terminals and one terminal(oftern manked N) has three wires on it then there is a very good chance your motor is DUAL VOLTAGE and can be used with a single stage converter, Dave.
