Product Description

1. The case is made of light, high strength 7075 alloy with blaster and black hard anodizing to prevent it from oxidation and corrosion.

2. High quality ball bearing ,very low noise and vibration.
3. The rotor has good dynamic balance,the vibration of the motor is very low .
4. The magnets have very high magnet 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 and water cooling .
8. The shaft is made of SS316 stainless steel, which enables it to work in seawater without corrosion.
With an advanced 10-pole encapsulated core and 85mm
diameter, this series compact DC motors deliver high torque up to
30 N.M with maximum output power at 20KW.
Thanks to the unique sealing configuration design, these motors
are tested waterproof IP68 according to ingress protection class,
and can be operated permanently underwater and applied in dusty
environments.
We can also customize the winding to perfectly match your
voltage, current, and maximum operating speed. Special shaft
modifications, cables and connectors are available upon request.

Can be customized for 

- Sensor or sensorless
