I'm looking for a 12V DC motor for a prototype.  The motor will be
attached to a crankshaft that will be lifting a steel plate that is
pivoting on the ground.  It needs to have ~30 in lb of torqe and be
geared down to ~15 RPM's.  The following link is a manufacturer that
offers a product that would work, but they will not sell in small
quantities.  I am looking to initially purchase 1 for the prototype,
and then to purchase in a larger volume.  I believe I should only have
to pay ~$15 at most for this motor.   Note: although I am flexible in
size, the unit should somewhat resemble the motor in the linked page
below (smaller is most likely OK, but anything too much larger or
ESPECIALLY anything longer would be a problem).  Thanks!

I great answer will include the product #, website, and specific
details about the unit. If more than 1 are found, information about
the units that best fit and are the lowest price would be most
important.

Are you looking to purchase only in the USA?
Will you be interested in surplus motors?

Usually a Distributor will give you a sample for free.

I am more than willing to purchase from any country to be delivered to
the US, particularly if it were cheaper.  I'm not sure about a surplus
motor; it would only be OK if one were available now for a prototype
sample as well as in larger quantities over the next few years...  If
a distributor would give out a sample for free, that'd be great!

No one seems to be answering - is there no researcher interested or is
the price too low?  It seems like it would be an hours work, at most,
which is how I priced the question....

Hi
I did take a look into your request. I still think that if you contact
a local dealer you will be able to get a free sample for your
prototype.

Keep in mind there is always ebay http://www.ebay.com for surplus items.

Also this site has surplus motors you might find interesting: 
http://www.candhsales.com

You can contact manufacturers/distributors via this site:
http://www.globalspec.com/  (email your request to multiple vendors in
one click).

Maybe you will need to supply additional data:

1: What is the annual usage?
2: Is this for an existing product or a new application?
3: Is noise a requirement (i.e.: Max Dba level, Sones level etc.)
4: When would production motors be required?
5: What is your price target?(given $15.00 )
6: What is the duty cycle (i.e.: time running and time not running and
at what load during the run cycle)
7: do you need a bi-directional or uni-directional motor?
8: If uni-directional ,  what rotation direction CW or CCW?

An online store you can browse and purchase from: http://www.bodine-electric.com/.

As for the price - well, the more you pay - the more interest
researchers have in finding an answer.

I hope this will help you.

I don't understand any of the technical details, but Bosch makes many DC motors.
Click on that at the left on this page:

Here is another Bosch site:

http://www.boschautoparts.co.uk/mcMoto1.asp?c=2&d=4

I chose the first one because it is labeled "automotive aftermarket",
which sounds like one could buy an individual item.

This one could also be of interest as it is for non-automotive applications:

Here is a site that lists many manufacturers:

as does this one, of course, to give our host credit:

I searched with   bosch dc electric motor  
No, I have no connection with Bosch.

Hope that helps, Myoarin
