· A lot of 75 HP 3 phase motors can be wired either for 230 V or 460 V. Might be that the motor you have is like that. If so, I would just skip the transformer and wire it as 230 V. If you end up using a transformer for whatever reason, I would point out that you may well end up with the transformer in saturation when the motor starts up.
