TMI-2

3VDC - 6VDC Vintage Miniature DC gear motor - Given the brand and the construction style (metal plates mixed with nylon gears), these were likely pulled from vintage or industrial electronics, such as:
* VCRs or Cassette Decks: Used to eject the tape, drive the capstan, or move the read/write heads.
* Camcorders: Used for the zoom lens mechanism or auto-focus.
* Printers/Copiers: Used to feed paper.
* Vending Machines or Coin Mechanisms: Used to dispense items or sort coins.
Summary
You have high-torque, low-speed precision motors. They are excellent for hobby robotics or repair projects where you need to move a small mechanism with a specific amount of force.
