I have a bad HOCB motor that came out of a Franklin Arsenal Intellidropper. It’s 12v but I don’t know the
rpm. Anyone out there have any idea?

Thanx,
Gene

Hello, Gene.

Are you sure it is one of our gearmotors (the N20 form-factor of our Micro Metal Gearmotors is very common)? Does it have any identifying markings inked on the side? You might try contacting Frankford Arsenal to see if they have any specific recommendations for a replacement.

Has no marking on the motor that I can find unless it is under the mounting bracket which I am trying to remove. I have contacted Frankford Arsenal but they have not yet responded to me. I’m thinking of trying to figure out the max rpm for a working unit. It obviously runs at different rpm’s so I’m assuming the variable speed comes from varying the voltage. Is this true? Looks like the 12v motor comes with different rpm values. I was hoping you might be able to tell from the picture. Any assistance you could give would be appreciated.

Thanx,
Gene

I opened up the motor and it has the Precious Metal Brushes.
Obviously not encoder and no extended motor shaft.

Still not saying it is your motor but I purchased one as a test and also feel if it is not the right one I can always use it for another project.

Yes, for brushed DC motors, the speed is proportional to the applied voltage like you described. However, please note that even if you get one of our units with a similar speed, it might not work for your application. The other factor to consider is the torque (which is essentially the rotational force the motor can apply). Unfortunately, the operating voltage is not enough information to go off of, and even if you knew the speed, it would be difficult to recommend a suitable replacement without knowing the torque requirements of the system.

All good information. I’m still hoping that Frankford Arsenal might get back to me. But I’m guessing they don’t have the details about the motor that you are talking about. I’ll let you know if I have any luck with figuring this out.
