Nema Stepper used in Flashforge 3D printer I am using Flashforge Creator Pro and a Flashforge Finder



I want to know which NEMA stepper model is used in each of these two printers, or is it NEMA 17 for both? 

Their model numbers are:


42HB40F08AB-04 [W-42MM, L-40MM], and;
42HD4027-01[W-42MM, L-40MM]
Nema 17 is about the physical size of the motor, ie screw hole placement. It doesn't specify anything about the power of the motor. If you are looking to replace the motor, you need quite a bit more info than that it is Nema 17, such as the steps/rotation and the holding torque.
