johnj, you can get the number of poles your original winding has by looking into rater RPM's. Because where you live the grid frequyncy is 50Hz, it means that a 2 pole motor is rated at 3000rpm, 4pole at 1500rpm, 6 pole at 1000rpm, 8 pole at 750rpm etc..

the link you posted to another forum doesn't work, at least for me.Edited by Janne 2009-01-21
If at first you don't succeed, try again.
