WD40 ("Water Displacement" product attempt number "40" for protecting
aircraft and missile wings etc from moisture see
http://www.wd40.com/news/in-the-news/so-whats-in-a-name/
) is designed to leave a sticky residue to repell water, this has the
unfortunate effect of collecting dust and muck and finally gums up the
motor. As John says if a bearing has seized it can be usefull for freeing
it but then you need to remove the WD40 with eg alcohol before adding a
small amount of lubricant to it.

I recall WD40 being 'showcased' on BBC's Tomorrow's World.
A rep from the company sprayed a domestic DIY drill and plug with the
stuff, started it up and then put his hand and drill into a tank of
water. The BBC guy said he could not do it because of insurance
purposes !
Have you tried cleaning the motor with alcohol and testing it again ?
As said above remember to add a SMALL amount of lubricant to it.
