Can i buy a new motor for my dewalt table saw?
you need to check and see if it is the field or the armature that needs to be replaced. if you can use a volt ohm meter you can check these two items. you would use the ohm or continuity part of the meter. for the field, there is a wire coming fromthe elect source and the a spring around the brush holder. the are two of these field coils. if you take one leed to each end and the wire is ok the needle will move or you will see areading ont he digital readout. if you do not get a reading, there is a break in the wire and the field is bad. on the armature, using the same set up on the meter, hold one probe on the commutator. the commutator is at the end and is made up of copper rectangles. put one leed on one rectangle and then use the other leed to touch all the others one at a time. if you do not get a reading on one of the rectangles that means a wire is broke in the armature. if they both showgood, you have another problem. which would be your switch or cord.
