New 6374 150KV Fully Waterproof Motor for Electric SUP Efoil Esurf DIY Electric Foil Assist
Our advanced waterproof technology for motor:
Rotor magnets with anti-oxidation and anti-rust treatment;
Stator with insulation paint;
Coil Copper wires with transparent insulating varnish;
Wataerproof ceramic 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!
