I motorized this cat toy and the motor overheated what's a better one to use? (lemmy.ml)

Clearly I'm using the wrong motor, I though I had calculated it out but apparently when it's under load (the mobile part) it heats up to the point that it melted the hot glue holding it in place. Not great, how do I rectify this?

Video of the motor working

Here's the assembly, that's a three AA battery pack

All parts in question Button, Battery pack, Motor

If anyone has any idea of what motor could handle this or what math I'm not calculating for I would really appreciate it

The torque of turning the toy and the speed in that video mean you probably need a gear reduction or a motor/motor kit with lower rpm and higher torque.

Something close to 3-5+ Kg.cm (higher is better) is probably going to work better and keep in mind rpm or rotations per minute should be a lot lower than 12,000 for your use.

I actually do like the speed it's going at but yeah, when there's no load its crazy fast, I'll see what kind of motors I can get my hands on
