tooljoe Posted June 4, 2011 Report Share Posted June 4, 2011 The reason Iâ€™m asking this is because can motors first need to be â€œbreak-inâ€ in order to get the full performance out of it. Donâ€™t take my word for it, there is plenty of info about this on the wed but I will provide some of my own pictures to illustrate such pointâ€¦ Here one can see how the brand new brushes do not make full contact on the commutator hence causing stuff like not full amp draw and over heating, for example. Now here is a picture of a non-can drill motor where the brushes are already pre shaped to hug the commutator out of the factory; therefore, getting the most one can get out of a DC motor out of the box. So are all tool reviews done when the can motor has not been broken in, just curious? Thanks. oh, here are the direct links to view the pictures clearer... http://tinypic.com/view.php?pic=kbyds7&s=7 http://tinypic.com/view.php?pic=o9he&s=7 http://tinypic.com/view.php?pic=scz3nt&s=7 Quote Link to comment Share on other sites More sharing options...
