My geriatric cats love this toy I bought a couple years ago and it's starting to malfunction. It stops whipping the feather attachment and I can hear an unnatural noise from the motor. I managed to order a used unit on Amazon but would like to try replacing the motor and have two working toys.

I see no identifying marks on the motor. Anyone have any idea where to find a suitable replacement? The unit runs on 3 AA batteries.

Thanks

Most likely you will find the more common 6v versions.
It does not appear to have a gear box, so I am assuming that rpm is not that important?

Without the plastic "whip" with a feather attached, the motor spins quite fast. Under load it it's about 1 rotation per sec. The cool thing about this one is that it "randomly" changes direction, I assume a feature of the PCB, nothing special about the motor.

I'll buy a couple candidates from amazon and try them out. 3-6K RPM seems reasonable.

I'm not a EE, that capacitor I presume is needed on my replacement?

Without the feather and plastic whip the motor screams and I can't estimate how fast it's turning. Fully attached it's probably more like 3 revs/sec. I'll buy a slower motor and try that too.

After measuring the motor (23.5mm x 27mm) I found a replacement on amazon as part of a kit, $15. It's rated 6000 RPM at 6 V, I'll give it a try.
