Hi,
I’m new to electronics and I’m looking for a 1200 rpm (spinning continuously) DC motor for a POV display project.
I need advices, which one can I buy ? I don’t know how to calculate the torque and load on the shaft I need.
The motor will be used to spin a PCB (led strips + chips).
I’m going to make something like this :
Thank you !
Hey @AudioVOX ,
I tried the sizing tool but I don’t think it fits my need, I’m not making a robot, just a POV display, like in the preceding link I posted.
And something I can’t set is the “Desired acceleration”.
My motor will just drive a PCB of 64g to 1200 rpm.
The data I entered :
total mass : 64g
nb of drive motor : 1
Radius wheel : 0.25 m
Velocity : 31m/s (correspondind to radius x rpm, 40 π * 0.25)
Max incline : 0
Supply : 12 v
Desired acceleration : I don’t know
I estimated that you would need a ~1.5kg-cm motor for the torque.
I have found this motor which could fit your needs:
Could you go with a faster motor?
If so, this would should fit to your needs:

Ok @AudioVOX thank you very much !
I think I will go on the Banebots (gearmotor is too loud for me) !
@vphongph - I am working on the same POV project and have run into motor problems, Did the Banebots 555 work good fro you and did you use 1.5v as the tutorial indicated.
TIA,
Jackie
