Phil,

correct.  You cannot accidentally convert an induction motor into
a hysteresis motor.  A hysteresis motor uses a different type of
armature made of a special metal with a large hysteresis value.
There are no embedded cast aluminum bars, etc,  in such
an armature.

Yes I'm sure your motor is successfully modified now.

I think you have solved things. Prior to modification the speed was 1440
[just under] on a decent hand held tacho. Now it is 1498 - 1501 rpm
variable. I checked it this time using an electronic rev counter 
[Microset
Clock Timer, that uses a photo electric] The mechanical one also gave 
1500
in this instance.

I am presuming you can't convert an induction into a Hysteresis by 
accident
using the pole shaving method, if so mine would appear to be correctly 
done
at 1500 rpm.

Phil
