Sticky motor

As mentioned in my previous post, I have one NEMA-17 motor that is “stickier” – more force required to hand turn – that the other three. I hadn’t checked or noticed this until I had installed it on the right Y-plate, and been moving the gantry up and down the Y-axis in adjusting the belt and fiddling with the eccentric nuts on the Y plates. The sticky motor ended up making the whole plate stick - travel - stick - travel, etc.

When I disassembled the gantry to get a lost screw in the X Carriage, I undid the right Y belt to see if maybe the,motor was making things sticky, and sure enough, that was the problem.

Questions:
I’ve read some more about the motors, and it appears the sticky motor might just be a little locked up from manual turning with the wires shorted. Is that likely, or should I get a replacement motor? Will any NEMA-17 motor work, as I can have one Amazon’d here by tomorrow. I still need to put in the Z-motor – that’s where this last one would go.
