Foil Assist Motor 6374 150KV Fully Waterproof Brushless Motor for Underwater Thruster Electric SUP Efoil DIY Electric Foil

Foil Assist Motor 6374 150KV Fully Waterproof Brushless Motor for Underwater Thruster Electric SUP Efoil DIY Electric Foil

Our advanced waterproof technology:
Rotor magnets with anti-oxidation and anti-rust treatment;
Stator with insulation paint;
Coil Copper wires with transparent insulating varnish;
Wataerproof ceramic bearing or stainless steel bearing.

Some other waterproof motors stator and rotor are full filled with black glue. This kind of black glue may expand when motor heats up, it will expand, then distance between the stator and the rotor will be very small. If rotor and stator scraches each other , it will affect the life of the motor. 
Moreover, if the rotor and stator are full filled with glue, the motor will heat up more easily and the motor power efficiency is poor.

Our waterproof 6374 motor insulating paint is harder than above normal black glue, and even if there is heat, it will not expand to affect the space between the stator and the rotor. It ensures longer motor life!

Difference between ceramic bearing and stainless steel bearing:
Stainless Steel Bearing:
1. Because seawater is corrosive, after some time use may get rust, need to wash with fresh water everytime after use, and keep the motor all dry, so to expand lifespan.
2. Can withstand higher speed.
3. Cost is less than cermic bearing.
Ceramic Bearing:
1. Better anti-rust performance, good for sea water condition
2. It’s brittle, can’t withstand very high speed, easier damage at high speed
3. cost is higher than stainless steel bearing.
