Encoded Gear Motor Shaft Click

Just wondering if I can somehow fix the vertical movement in my encoded gear motor. I can pull on the shaft (hahahaha…yes, very funny) and there’s movement in it. The problem is that I’m using the motors for a sensitive gyroscope/accel project and that sort of play in the shaft is not very good for accuracy.

It’s the 131:1 37D model. pololu.com/product/1447

Bump. No one?


I checked and measured the amount of movement on some of the motors we have here. I found that the movement was less than 0.5mm on the 37D motor shaft in the axial direction. Unfortunately, we do not have any recommendations for how you might reduce the axial play.
