Where to buy one 18 V cordless drill motor? (USA)

[John Doe]

Any good online merchants that sell the equivalent of cordless drill
motors from 14.4 to 36 volts? Any online stores that sell similarly
powerful DC motors in quantities of one?

Partly out of curiosity. How much would you pay if you had to buy a
motor separately and needed a motor like the following 36 V cordless
drill uses? Or would you pay less by buying a drill body off of
eBay/wherever and using the motor from that?

I'd put a WTB ad in my local Recycler newpaper.
**Battery-powered drill wanted. Dead battery is OK.**
Bet you get more calls than you can handle.

You're thinking too linearly.
I always think *surplus* first for a one-off item.

There you go.
There are lots of tools out there that guys won't buy a battery for.

Yep. I see them all the time in the second-hand stores: Goodwill, ARC,
The Salvation Army, etc. It's my observation that they are donated
(i.e., tossed) because the battery went bad and it was discovered that
the price of a replacement battery was more than a whole bright, shiny,
new kit.

The problem I have with a cordless drill motor that comes inside of
a cordless drill is that it has a very short shaft with a gear stuck
to it. I need a motor with a minimum 1" shaft without a gear. The
other properties of a cordless drill motor are very well suited for
my project, especially the fact that a cordless drill comes with a
battery holder and a controller.

There are numerous power tool parts vendors on the internet.
For example, for Black and Decker drills:
<http://www.toolpartsdirect.com/blackdecker/blackdecker-7.html>
One of several 18V drill motors:
<http://www.toolpartsdirect.com/cgi- bin/schematic.cgi/blackdecker/CD180SK_TYPE_1>
Item #15 is the motor for $8.31.

I looked up a cordless circular saw on that website. I had hoped that
a cordless circular saw would have a longer shaft. If that circular
saw was typical, at least now I know better. Makes sense that a motor
shaft intended to do work has a gear stuck to it (or maybe a bevel).

I need to connect the motor shaft to a 5/16" diameter rod. I might try
finding/buying some steel tubing with an outer diameter of 5/16"
(maybe from McMaster), then machine the drill shaft/gear down to the
inner diameter of that 5/16" steel rod, and then roughen the outer and
inner surfaces, and then glue them together. At least that's probably
better than the last way I stuck a roller to the cordless drill motor
shaft. Just need to keep the metal sawdust out of the motor.

Thanks to the replies.

No, If you want a hand-held tool motor with a long shaft, get a rotary
tool, die grinder, router, or laminate trimmer motor. most other
hand-held tools have gears. but these ones are direct-drive and the motor
will terminate in a collet chuck (should be real easy to couple to whatever
you want)

Try using a shaft coupler. You can probably get one from an industrial
supply outlet for minimal cost.

Cordless? Has to be a DC motor.

I think most cordess maotors are geared.
I have remains of a cordless somewhere (think I know which box it is
in!) which I will find and check the shaft and could send you.
But probably not much point sending from here in eastern Canada when
you could get a second hand cordless drill from some junk store nearby
for a few bucks and take the motor out of that?

Yeah. I'm also looking for a juicy NiHM or lithium-ion power supply
(battery/holder/controller). Mainstream tools are cheap. Panasonic's
NiHM powered 18 V cordless drills come with 3.5 amp hour batteries.
A Bosch 36 V drill comes with a two amp hour battery. I guess that's
the equivalent of a four amp hour 18 V battery. Lots of amp hours.

Extraneous stuff.
Currently I'm looking at calipers/micrometers. Planning to shield
the motor and carefully grind the gear down to the inner diameter of
an aluminum tube, then push the tube onto the gear. I was going to
limit the outer diameter of the tube to 5/16" but I'll probably need
maybe 1/2" or larger. The greater tube outer diameter will require
larger inner diameter bearings (than 5/16" ID 608 ball bearings,
cheap and common with in-line skates) that the tube is going
through.

What about a model store ? Radio control model cars use mighty powerful DC
motors with long shafts. You can probably find something of a suitable size
/ power / voltage at reasonable cost. Also, many small powerful motors used
in cars - for instance, electric windows, electric sunroof, central locking,
electrically steered door mirrors, heater control valve / vent flap drive,
electric seats. Visit to an auto junkyard, where these items might already
have been removed for sale, perhaps ?

Speaking of radio controlled toy cars.I would like to find a hollow
rigid plastic ball that is easy enough to take apart in two pieces.I
want to put a small radio controlled toy car inside of the hollow
plastic ball and try it out.
