Hi,
WOW David what a lot of information to wade through and I'll be looking at the sites later with great interest. Many thanks for adding the information.
Regarding 3 phase motors; the very old 415V Star wound motors found on our vintage machinery are unsuitable for conversion because the "Star" connection is usually buried too deeply and trying to locate it usually destroys the winding. The more modern 3 phase motors though have the leads running to a terminal block giving excellent access so these can quickly be re-connected in "Delta" in fact many motors are supplied already fitted with three links which are simply re-arranged as required to give either Star or Delta connection.
VFD's (Inverters) are now available quite cheaply; these are becoming increasingly popular for home workshop owners who wish to run three phase machinery at home and I can confirm these VFD's are an absolute bargain given the technology involved.
An interesting thread David; I hope it attracts lots of replies.
Kind regards, Col.
