SOURCE: dewalt dw744 motor runs slow and smokes, what

probably whole motor, if the bearings started to seize up it could have caused the armature/field to burn or if you overloaded the tool the same thing would happen. Does the tool have a burnt electrical smell, if so the motor is burnt and the cost of parts might outweigh getting repaired, You can go to Dewaltservicenet.com and find out the prices and also you might want to call a Dewalt Factory Service Center and ask them about the MAX repair rate on this tool and they will fix everything for that price, no matter what.

Hi. I have a dw744 and the motor started to sputter/vibrate and spark a lot. How doe I know if I need to replace the brushes?


Not Much on saws but it is alot like a starter motor and if the Brushes wear down it will cause metal to metal contact with the armeture and will cause them to spark and soon wont work.

The motor sometimes starts right away and at other times I have to use a wood stick to spin the blade and it starts


the brushes in a dw744 have a ledge when they get too short that hangs up. replace the brushes and you should have no problem. the brush holder comes right out with a little coaxing with a screwdriver after the end cap is removed. it just plugs right in.

Where do i buy an arbour for dw744 table saw


If you have a type number of 4, an assembly will have to be replaced, not just the shaft. THIS COULD BE DIFFERENT IF YOU HAVE A DIFFERENT TYPE NUMBER. It can be purchased online through DeWalt, but verify your type number before ordering.

Replaced armature and brush's and there is alot of heat and spark and it starts slowing down?


Unless somewhat preformed, brushes have a tendency to arc like crazy and can produce heat and even smoke. I would remove the brushes and use a fine 'keyhole' type file to give them a little inside curve so they have better contact to start with.

DW744 table saw


Balde movement up and down? If so, that would suggest worn bearings in teh gearbox. If they are worn there then they might also be worn in the motor. If this happens the armature will float up and down causing it to rub against the stator. You may be able to get the bearings sorted without needing any new motr parts. I beleive this saw uses an induction motor so beware if it does need replcing you might want to be sitting down when you get the quote.
