Miniature two phase four wire 5MM stepper motor with planetary gearbox. The planetary gearbox adopts an all metal structure, including a metal outer wall and secondary metal gears, which then drives a precision inclined shaft to move the metal slider up and down. The bracket is basically made of metal, and the shaft is fixed with ultra micro precision ball bearings. The precision of this mini planet gearbox is amazing. The outer diameter of metal planetary gearbox is only 4.9mm, and its planetary gears cannot be seen clearly with the naked eye. It can be identified only by using an magnifying mirror. The end of the driver's rod is fixed by a super miniature ball bearing. The entire metal sliding table is also very precise and stable. The connection of the motor, gearbox and metal sliding table is made by laser welding, which is very precise and solid.
