Having no three phase supply, I recently decided to convert a large pillar drill I acquired a few years ago, from three phase to single phase power. First of all, I went to a local motor rewind specialist and asked if they could convert the existing motor. They said they could but it would be altogether better to just put in a brand new single phase 1hp motor; a four pole motor giving the correct 1500 RPM. I have now fitted this motor and the machine is excellent. - the single phase supply has enough capacity to cope with the load.
My question is this: can this approach be used on other machine tools; lathes and milling machines? Have I just spent too many years being put off larger machine tools by the installation of three phase power, or an inverter? Are there any disadvantages to using single phase: less smooth power delivery or lack of torque?
OK, I realise this is three questions but any advice about the maximum size of machine I could consider running on single phase power would be appreciated.
