1. Multiple Accuracy Machining: The trolley motor has a high accuracy shaft, multiple accuracy machining, and has passed strict dynamic and static balance tests to ensure smooth operation and low noise.
2. High Strength Magnetic Tile: The trolley motor with high strength magnetic tile has long life, strong power and large torsion.
3. Fully Enclosed Structure: The trolley motor adopts a fully enclosed structure, which is small in size, which can effectively reduce weight and save space.
4. Pure Copper Material: Pure copper winding, pure copper coupling, low resistance, quiet and durable, low heat generation, low loss, and powerful operation balance.
5. Application: This is a car motor that can be used to make balance cars, DIY smart cars, and electric toys.
