Hi.
I’ve been taking a look for the Pololu 50:1 Micro Metal Gearmotor, and I want to use it for my project.
The problem is that I havent found any good wheel for this motor. I like Banebots and neoprene wheels but I think that the appropriate hub doesnt exists (at robotshop.com) for these wheels.
Can you help me?
Thanks.
At the end, the project exceeds the weight limit. So I return to my previous version. Im going to use the Pololu 35:1 motor, so I need to re-elect wheels again.
Last time, you said that using RB-Ban-155 hub with 2 RB-Ban-107 wheels are too much for this motor.
Using the Drive Motor Sizing Tool I’ve seen that with two of these motors, I can move 1kg without problem.
If i use 2 of these motor at max current, it would be ~10A. What do you think about using a 3,3Ah, 40C battery?
Only 15 minutes of autonomy would be enought.
Ohhh, 4-7/8" its 4’875" !! I never saw something similar…
I can change the hub, its not a problem. But, do you think is to much wheel for this motor?
It should go at 1m/s and good acceleration carrying 0.7kg, also 0.3-0.4m/s with 1.4kg
The motor’s shaft is 3mm in diameter, and Pololu makes various diameters of wheels which will press-fit right onto the shaft (see cross-selling). If you want to use a BaneBots wheel, you would need one like RB-Ban-151, which has a 3mm bore and 1/2" hex mounting (0.4" wide). This would mate with RB-Ban-91 which has a 0.5" hex bore and is 0.4" wide.
That hub does not connect to the sumo tire. Also, that motor would likely fit entirely inside that sumo tire and likely won’t be powerful enough for your needs.
Yes, but you would need to glue the shaft in place since the bore is 3mm and there is no set screw mount.
