How should I find a motor that fits these descriptions?
Right now I am using non commercial 9V DC motor. I want to get a commercial motor (what i mean by commercial is being sold wholesale or a radio shack or something) to mimic this motor. I know the specs and everything of my current motor I just don't know what numbers to use when looking for it.
Here are the specs:
No-load rotation speed: 170rpm
No-load current: 60mA
Torque: 16.7N.cm
Current: 0.55A
Mechanical Power: 2.03 W
Electrical Power: 4.95 W
Efficiency: 41%
If someone could tell me a place to find this specific motor, or a place which has a high probability of selling a motor like this. And, what I should look for when I am at a website (i.e. look for a motor with matching voltage and current or something) I would greatly appreciate it. I really don't even know how motors are catoragized so really any help is welcome.
Thanks!

At 170 RPM, I think that there must be a speed reducing gear built into the motor. That would make it a "gear-motor." The no-load speed and current are not very important. The most important specifications are the maximum operating speed and the torque and voltage at that point.
For wholesale purchase, I think it would be necessary to buy in very large quantities directly form a manufacturer who would make it to suit your requirements. For small quantities, you might find something sold for developing prototype products or for educational purposes. Educational or toy building kits such as Knex, Erector Set or even Lego may have motors that would be suitable.
