Key Features

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.
High quality ball bearings ,very low noise and vibration.
The rotor has good dynamic balance and the vibration of the motor is very low.
The magnets have very high magnetic strength and temperature limit can reach up to 150°.
H-grade ,high temperature copper wires with high insulation.
41KW high power density, high torque at 66N*M, high efficiency at 93% and Up to 8,408 rpm.
Water-proof Level IP68.
Motor housing made of light,high strength 7075 alloy with blaster and black anodizing to prevent it from oxidation and corrosion.
Available in three versions: water-proof feature, water-cooling feature or water-proof and water cooling combined.
