Now my head hurts...Whats with 240V 3 phase I thought 3 phase was 415 volts??

I am giving my unit up as I cant justify the cost and I have a colchester master running of 3 phase 415 volt AFAIK.

Its supposed to be 2HP so I priced up a 2HP digital inverter. They seem to work out about 100 quid per HP BUt then I start reading and I now think I have a 5HP motor in the lathe and need a 10 HP inverter which is over grand.

I might just as well sell up and go caravanning......;(

In the North America, 3-phase is commonly 240, 208, 380, 480 or 600V. 208 is the most common (three 120V phases.)

Most motors can be wired for either 208-240V or 380-415 three phase.

With 240V single phase in; it is easier to generate 240V 3-phase out than upping to 415V. So, with an inverter, you often jumper the motor for 240V.

You would normally get the same HP inverter as the motor. I don't see where you need 10HP.

Ah I am in the Uk so I dont know what this motor is capable of.

Also I got the size as I read this page.
