NEMA 17 Stepper motor
A NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (43.2 x 43.2 mm) faceplate. The NEMA 17 is larger and generally heavier than for example a NEMA 14, but this also means it has more room to put a higher torque. However, its size is not an indication of its power.

Shinano Kenshi
If you have a Shinano Kenshi motor in your hands, you can decode the part number written on it with the SKC Stepping Motor Part Number decoder at Shinano Kenshi: "Stepping Motor Operation & Theory".
Lin Engineering
Lin Engineering is one of the few manufacturers that make stepper motors in the US. If you have one of their motors in your hands, you can decode the part number written on it with the "Lin part number system" decoder on p.1 and p.2 of the Lin Engineering Catalog. Page 9 of the Lin Engineering catalog explains the part numbering system for all Lin Engineering stepper motors.
