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 .
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.
