    Did you do the work yourself? It could be a couple things, there is a bearing cup in the motor case that has to be installed properly, also is the armature sparking? If so it needs to be cleaned. Let me know and I will try and help

    Same issue here. I have replaced armature with bearings, gear reduction box with new gears, brushes, rubber bearing cup and field. The saw runs and will cut but it's a slow go. When you turn the saw on it's almost like it has a soft start instead of the jolt it use to have when starting up. With the new parts in this saw it should be running like new but it's not and it's driving me nuts as to what could possibly be causing this.

Bosch 4000 table saw motor schmatic


http://www.ereplacementparts.com/bosch-4000-0601476139-table-saw-parts-c-128_167_168.html
I have found the most common issue is a bad field with the second being a bad rear armature bearing and last being a bad speed control.
Most of the time slow speed or even running backwards is a bad field (part #2 on the breakdown) #1619PA5590
Remove the cap on the end of the motor & the 2 carbon brushes.
Remove the 4 screws holding the motor to the frame and pull it straight off.
Check the bearing on the end of the armature to ensure it is not frozen or stiff. If it is also check the rubber boot that sits over the bearing and the motor housing itself to ensure it is not melted.

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.

I was cutting 2" dense foam insulation board,


The problem you have is a faulty field coil, the Bosch saws unfortunatly have a bit of an issue with this. The coil can be replaced separatly so you won't have to replace the whole motor. Bosch has a 1 yr warranty on thier table saw so this is a warranty replacment provided the saw was purchased within the year. If not the coil replacment is still cheaper than buying a whole new saw, but should really be done by a service center because of the level of difficulty of the repair.

Hi it seems like their is no power but their is, the motor is very hard to turn by hand? I'm assuming the bearings are gone. what do you think any history on these similar problems


bearings in a table saw are always a problem, but the replacement cost is cheaper than a new saw, but also if you have possibly overloaded or tried cutting with a dull blade the electrical system might be out. I would think the bearings first though.

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.

Dewalt dw744 motor runs slow and smokes, what parts need replacing?


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.

The saw has stopped I know the circut it is plugged into is live is there a reset button or built in breaker located on the saw? Dw744 10 inch table saw


NO reset or circuit. You can try and unplug tool and blowing into all the exposed areas of the bottom of the saw. WEAR safety goggles. Then what I would do is check the brushes and if you have a volt ohms meter check the continuity to the brush tubes. Start at the cord looking for a break in wiring and go from there. Let me know if you need more help, but I am going to thing brushes or switch

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.
