One important thing to note is that the wire color of the motor is not always meaningful. To determine the pairs, simply spin the shaft and touch two wires together. If it becomes more difficult to spin, those two wires are a pair. The other two wires will then form the other pair. This method makes identifying the pairs very simple. It's worth mentioning that it's not uncommon for motor wiring color to be meaningless. Additionally, if you take your motor apart, you risk damaging it, so it's best to avoid doing so.
I've noticed a lot of concern about heat, but it's important to understand that these motors can get quite hot without any issues. If you can't keep your finger on the motor for more than a second without burning yourself, then it's too hot. Otherwise, the heat is perfectly normal.
Changing the spin direction of the motor is easy. You just need to flip any single pair of wires, and the motor will start turning in the opposite direction. If you flip both pairs, nothing will change. Swapping pairs from A to B will also change the direction. Remember, you only need to flip a single pair to alter the direction.
In my case, I was using this motor for a geared extruder on my 2.85mm filament-sized 3D printer. I had previously been using a standard 40mm NEMA 17 motor, but I encountered issues with skipped steps when extruding the larger diameter filament. I had to increase the motor currents beyond the rated amps, yet the skipped steps persisted. This is when I decided to order this stepper motor.
The higher current limit and torque rating of this motor solved my problem. It runs much cooler because I'm no longer supplying it with excessive power, and I can tune it to prevent skipped steps during extrusion. I would definitely consider purchasing this stepper motor again for similar applications. I've even thought about replacing the moving y-axis stepper motors on my 310x310mm bed-sized printers with this motor due to the added stress that such a large print bed puts on the motors.
One thing to keep in mind is to double-check the pinout in the connector to ensure it matches your stepper driver outputs.
