Features: The low-speed metal gear motor supports clockwise/counterclockwise rotation to meet different needs. Miniature metal gear motor is impactresistant, low-noise. The copper coils of the miniature metal gear motor has strong conductivity and low heat generation, which makes the motor output stable. The metal gear motor has 3 layers of high-density moleculars coatings, which can effectively isolate dust, resist high temperatures and have a long service life. There are high-density moleculars coatings on the outside of the motor, which can effectively isolate dust, resist high temperatures and have a long life. Copper coils has strong electrical conductivity and low calorific value, which makes the motor output smoothly.
