Thanks for the reply,
Well basically the motor can be rotated easily, if i disconnect the pulse 
and the motor spins to the end i can feel it locked into place and not 
easily moveable, but its nothing like that, also i have read about using a 
regulator (the 7805)as you have advised, but i will have to order one as my 
local electronics shop does not have it stocked at present in the mean time 
i found a 7905 which is a negative voltage regulator in some old parts, 
maybe there is some way to get this to work? or is there any other way to 
use something other than a regulator? maybe using common electronic parts.
