I would appreciate that. (Rest of my machine bined or I would have gone and looked)I have only ever come across this type of motor recently.

I know you can change the speed by the formula. RPM = (120 x Frequency) / Poles

So I just assumed that by changing the number of poles you change the speed. I did not think about changing the frequency.

Just goes to show you learn something new every day.
