Yes ! !
Most of it was over my head, k,i,s,s, but did get the general jist of what you were saying,
Thanks Les this did help explain.
Seem to have come a long way since my original question,
due to your help I have changed the motor, (took several things to bits) this one feels stronger.
My conclusion is, that my motor running on 0.03 amp at rest, will draw more when under load, as I have a supply of 2.5 amp I don't think this will be to much of a problem.
Due to your comments I realized the size of the impeller will make a difference, this I can cope with having a lathe (made from spin dryer motor,
seems I am better at engineering than electrics)
So it seems I am on my way to a solution,
thank you all again, it has been an insight to how complicated this electrikery can be,
