Features: 1. Smooth and consistent speed with no step loss. 2. Reinforced PCB board mounted to the motor; advanced stator design ensures uniform stator tooth finish, high-precision inner bore, and stable, accurate rotational speed during operation. 3. Stable mechanical structure for smooth operation. 4. Rotor surface coated with high-quality epoxy resin to minimize noise caused by surface imperfections on carbon steel after grinding. 5. Stable speed performance and low operating noise. 6. High stability, high-speed capability, and low noise—designed for compatibility with standard motion platforms.
