The precision of this miniature planetary gearbox is amazing. The new miniature two-phase four-wire 4MM stepping motor with planetary gearbox, the planetary gearbox uses an all-metal structure, including the metal outer wall and the secondary metal gear, and then drives the precision slanting stalk to push the metal slider up and down. The brackets are basically made of metal, and the poles use ultra-fine precision ball bearings.

Specification:

• Slide stroke: about 12 MM
• Motor phase resistance: approximately 14.4 ohms
