3 Phase Machinery on 240 v circuit

Postby Bangui » Mon Feb 09, 2009 10:18 pm

I have been given a 3 phase lathe and want to run it in my 240 v workshop. I know I need a converter, but there my knowledge stops! I have read that rotary converters are better than static converters for machines with a variable load - presumably a lathe is a variable load? I have also read about converters and inverters - what is the difference? I would like a converter/inverter that allowed me to control the speed of the lathe. Grateful for any help on what I should be looking for, and how I match sizes etc. Thanks, Bangui .

Simply Build It

If you know what specification the motor on the lathe is (Mainly how many amps are needed), then you can get an according inverter which can be supplied by a single phase and will have a variable 3 phase output.

I believe you can get inverters with built in interface for programming the speed.

Although it may be cheaper to get an inverter without the control and have a small panel built to do the control for you. This is the way I have seen it done, but it was a large motor and a huge inverter.

This wiki page should be helpful,

Hi there,

Where in the country are you? Let me have details of the motor as i have lots of inverters for sale.
