Panasonic OEM Replacement Motor. (DC-25 Animal) Pretty easy for a mechanical person. I was repairing a vacuum cleaner for a friend - the motor he replaced worked fine, but the impeller was destroyed by a pair of children's socks stuffed into the intake pipe. Replaced both filters to keep the new engine breathing. Be sure to put all the wires back in their little "tracks" when you reassemble the vacuum cleaner. Every wire has a place. Do not hurry. If your vacuum cleaner is still in good condition, it is worth replacing the motor if necessary. You will need a set of Torx screwdrivers.
