What Peter is saying, is that it is very possible to convert your machine to 230.
Your response is to the effect that you're not thinking that you're capable of doing the conversion... and that's an admirable admission.
What you need to do, is find a local industrial electrical guru who'd be willing to do the task for you... I'll bet that if you look up a bunch of other local machinery-type guys, you'll find at least ONE of 'em who understands the electricals of these things and can do it for you for a reasonable case of beer cost.
Here's what has to be done:
Find the motor. On the motor is a little diagram that indicates wiring connections for LOW (230v) and high (460v) wiring. Open up the motor wiring-access panel, look at all those wires- they all have little number tags. Disconnect and switch all the motor wires around to match the LOW diagram.
Next, find any OTHER devices (coolant pumps, control transformers, etc) and do the same- they'll usually have labels.
Next, find the motor-starter unit. It usually has at least one button (RESET) or even a pair of START/STOP buttons hooked to it... and inside is one or more iron things that look like relays. There's at least one coil in there, oftentimes more, and one or more 'heaters'. These heaters... there's one type required for 480 (high voltage, low current) and one type required for 230 (high current, low voltage). These things get hotter as more current flows through 'em... and when they get so hot, they shut the machine down. Of course, in a low-voltage motor, the current is higher, so they trip too soon... which is why we're changing 'em.
Now, after reading my explanation, pop off the covers and take a look... you MAY decide that it's not that complicated... but at least you'll know what needs to be done.
If you're not up to doing it yourself, find another local machinst-type, or a guy who's been an industrial electrician for years... someone who has set up machinery in an industrial environment.
