Compare small DC motors from different vendors
Compare small DC motors from different vendors
(OP)
I’m interested in finding the most useful criteria for determining the best motor for various designs. The motors would be of the small DC permanent magnet type. By small, I am referring to less than two inches in diameter. The motor could be brushed, brushless, or stepper. The motor could require a gearhead. I’m not trying to determine which technology to use. I’m more concerned with getting the best motor for the application from the offerings by different vendors. I’m restricted to the data in the catalogs they provide. I believe that some “specmanship” is involved in the catalogs.

For machine tools we use combinations of power density and thermal effects, with cost being last factor.
There are 100 ways to rate an electric motor, specs lie all days because they are not telling you testing method used for rating. Be sure to compare same ratings at same ambient/cooling system as many time low cost motor may have been tested different.
