I was thinking about you only a few days ago.
Not sure about your power thingy but I guess with that gear reduction you
will have 24x-ish the stalling torque that you started with. 3phase to
single? Something slightly better than half power perhaps. (1/sqroot 3)
springs to mind [sort of] LOL

Subject: [Vwdiesel] OT: electric motors
Sorry this is a bit off topic but I know there are people here who can do
this stuff in their sleep and to be honest electricity and me just do not
I have built a few felt rolling machines and on the last one I used a .65kw
3phase motor converted to single phase use with a capacitor. This I have
been told, reduces the power
available so firstly can anyone tell me how to work out what the equivalent
wattage would be now??
Secondly; it's running at 1450rpm, with a gearbox on it, resulting in about
60rpm output. Can anyone tell me how to work out how much
power/torque/momentum (or whatever it's called... ) is being produced on the
final drive shaft?? I want to know how "strong" it is...
I need a number and a unit so I can work backwards and find something that
has similar power/force capabilities, but possibly less kw/3phase/more
rpm/different gearing and final drive speed options...
You can tell I have no idea what I'm talking about can't you...
Any advice would be greatly appreciated...
