So would your calculations restrict replacing even a very low amp 3phase with a single phase? When I initially queried this forum last december with the prospect of replacing the motors, I received some positive feedback on replacing my low amp motors. I got the impression that if the 3phase motor is a low enough amp, then a single phase can safely cover it. The machine I have is not a heavy power consumption user, I am guessing the 3 phase motors are to ensure consistent running speed as the machine processes cine film, and any variation in speed will effect the final product.
At the moment the machine is running 240volt house mains on bare essential motors, without blowing fuses or dimming lights. I was planning on wiring up the remainder motors on a separate circuit with their own switches.
As I am not a business I have to explore work arounds. I have tried getting sparkies to attend and look over the machine but I am too far out of town, and it seems not many electricians come across VFDs to offer opinions.
This thread was my original, and lists the motor specs.

Adapting a 3 phase industrial machine to single phase
Hello, I am hoping this is in the correct forum. To start, I acquired a film processing machine that runs on 3 phase. Now before getting the machine I fully understood it's power requirements and the cost of getting 3 phase installed at my house. I figured as processors are mostly a few...
