How to remove stuck motor brushes from Dremel 300 to replace?

Motor does not run, only if I am continuously pressing one cover of the two brushes, indicating that they are worn out. I have ordered new ones(I've received them) but cannot put them in, because I am unable to remove the old ones!(Don't say that I have to disassemble the motor to replace this basic maintainance requiring part!)

SOURCE: dremel 400 xpr stopped working.

It could be the fuse between the brush and variable speed control switch. I have the same problem and found the fuse blown. I am hoping that I can replace the fuse without having to buy the complete speed control unit which is about $17.00 from Dremel. If yours is still under warranty you could send it back. If I can find a fuse for mine I will let you know where to get them. joatmontag

SOURCE: New Dremel 300 stopped working. What's wrong?

Something amazing just happened! On my monitor screen, window popped up that said, "ASK A QUESTION - LET OUR EXPERTS SOLVE YOUR PROBLEM FOR FREE".

I couldn't resist getting expert advice for free, so I clicked on the window. I was immediately taken to a magical world where I can pay for expert advice. I opted not to pay for expert advice. The next day, I was asked if the help I received was helpful. So here I am posting this response. I haven't received any expert advice yet, but when I do....!

Have a de walt mitre compound saw 712xe; it has been stored for some time, and does not go when I squeeze the switch.. there is definitely power on the plug.


there is few blocks (physical) which restrain it's movement, but electrical is only and only switch.

check cord to the saw, if power is positively on and no joy, you need
om-meter (resistance) and if you have, continuity meter (i made one from 1.5v battery, 1.5v bulb and about 3m of speaker wire, i done that in 1964 and i am still using it...)

!. unplug power supply
2. rotate blade by hand and check if it rotates freely
3. tap gently on the sides of motor where brushes are
4. remove brushes cover and check they status (sometime bit of dust get there and it is stuck preventing contact)
5. using compressed air - blow all dust from brushes and brushes mounts
6. replace brushes and covers
7. try to start machine again,

if no joy, to exclude cabling and switch:

!. unplug power supply
2. lift the switch cover (of the memory i think it is six screws)
3. check for obvious burns or acrid smell
4. check now for cable to the plug continuity
5. check switch working on both sides
6. replace cover
7. try to start machine again,

if all of these were ok - it will indicate problem with motor, check therefore motor electrical continuity and flows

i hope you will find this little instruction helpful, do not forget to vote :-)

Why does my Dremel run for 1 sec. then switches off If I knock against te side it runs 1 sec before cutting out off


sounds if your tool has a loose or broken brush this is a small carbon object inside that makes motor run, dremel does sell replacement brushes for most of what they mfg. look where ever real dremel bits and tools are sold ck package back to see if your model number is serviced by this brush pack

Location of brushes on dremel multi max kit


There should be a second brush. Look along the motor - you're looking for a spot where the armature (the part that rotates) is surrounded by a ring of little straight copper-colored bars. That's the "commutator" section. The brushes run against the copper bars.

Look on the outside of the plastic shell - there may be two large plastic screws, one on the outside of each shell half, right about where the commutator would be on the inside. Those are your brush holder screws; you should be able to change the brushes from OUTSIDE the tool without opening it. Some tools are built without external brush holders like that, but most have external brush holders.

If you find external brush holder screws, then track down the second brush and set it aside. It MAY be hanging from the brush holder in one of the shell halves. Unscrew both brush holders and remove them from the shell. Set them aside and reassemble the motor back into the shell. If the brushes are really short, like if they're nearly cube-shaped, then it's time to replace them. If not, try them again.

Insert one brush into each of the holes the brush holder screws came out of, and put the brush holder screws back in. Be careful not to cross-thread them. Try the tool.

If it still won't run, it's possible that an armature winding has given up the ghost and it's time to replace the tool...

Dremel 395 Rotary tool won't turn on or won't stay on but a second or two


Electrically speaking there are a few items to check.

1) The easiest is to remove the two brush holders screws on each side by the power cord. If one of the screws are loose, or the bushes are worn you will get intermittent or no operation.

2) Second use a volt ohm meter to make sure you have voltage on the two brush connectors inside the brush holders when power is on. If you do then open the unit a check continuity on the motor armature to see if it is open, which will cost $13.37. If you do not have voltage, inspect the power cord and switch.

Some parts can be purchased on the below link.

I was working with the dremel and it shut down and would not turn back on, the motor was not hot. I'm wondering if it has anything to do with the brushes in the side of the motor housing?


My dremel started doing that too. If I rubbed the sanding drum along a piece of wood, it would start up again. I think the brushes and the copper armature get glazed over with non conductive dust and possibly insulation smoke which disconnects it enough to stall out. Change the brushes to the new ones in the kit. After a year of heavy use mine slowwed down to about 300 rpm and then died. A very nice tool but I prefer the Makita which is about three times this size just because it is longer lived.

Motor works but no drive to shaft.


My 15 year old Dremel 395 had the same problem so I took it apart. There is a plastic spline between the motor and the output shaft to the chuck . My plastic spline was split and had many of its teeth sheared off. The shaft lock acts on the output shaft side of this spline, so it was ok. Otherwise everything looked great; bearings ran free & had little play free, brushes ok. To be fair, my Dremel had seen hard use & doesn't owe me anything. No luck so far finding replacement spline parts, which if available should be easy to install. To take apart your tool, just google "Dremel Disassembly". GOOD LUCK!

(I need a new electric motor for my air compressor. Where do I find one?


I think I can help you guys needing a replacement CC-5440M12 120V/60Hz Ronning Motor. I have been cleaning out my shop and I have four (4) of these used electric motors. All work fine. They still have the plastic fan blade on one end and the metal gear on the other. I actually have electric cords wired up on each of them that I used to make sure they worked.
Thought I would pass this information on to you. Thanks and have a great day.
