1. Rotor is designed with segmented and staggered magnets, which reduces eddy currents in the magnets, thus generating less heat, and allows the motor to have bigger starting torque,smooth start,smaller vibration and less torque fluctuation.
2. High quality ball bearings ,very low noise and vibration.
3. The rotor has good dynamic balance and the vibration of the motor is very low .
4. The magnets have very high magnetic strength and temperature limit can reach up to 150° .
5. H-grade ,high temperature copper wires with high insulation .
6. High power density, high torque,high efficiency and high RPM .
7. Water-proof grad IP8 .
8. Housing made of light,high strength 7075 alloy with blaster and black anodizing to prevent it from oxidation and corrosion
9. Available in three versions: water-proof feature, water-cooling feature or water-proof and water cooling combined .
