Dc5V Micro Tiny 5Mm 2-Phase 4-Wire Stepping Motor Precision Planetary Gearbox Gear Stepper Motor Linear Screw Metal Slider Block

Specification: Very and precise micro stepper motor. There are 3 model linear screw stepper motor, they use full metal planetary gear, with ball bearing in the screw end. The motor A is made by Nidec, B and C is Chinese Manufacture, the workmanship is almost good as Nidec. These motor widely use in mobile phone lifting camera or other high end device. The video test the B motor with stepper driver module for your reference. Feature: Micro 2-phase 4-wire stepper motor,with planetary gearbox. The planetary gearbox reducer adopts all-metal structure, including metal outer wall and secondary metal gears, and then drives the precise skewed grains to move the metal slider up and down. The bracket is basically made of metal structure, and the screw uses ultra-miniature precision ball bearings.
