Economical in terms of power consumption and does not generate heat.
Lao Zhang drives an electric three-wheeler for deliveries. Every time he reaches a long slope at the overpass, he gets frustrated - the motor keeps making a loud buzzing sound, and the battery power keeps dropping like water flowing through a dam.
We spent three years figuring out the ins and outs of this. We found that the rotor of a regular motor gets hot as it rotates, and all the energy is wasted in the struggle. Now this version of the brushless motor is like giving the car a never-failing little leg:
The copper wire winding method is like fish gills.
The heat sink can "breathe" by itself. It can continuously climb a slope for 2 hours, and the outer shell feels warm just by touching it.
Smart power-saving trick
On flat roads, it automatically switches to energy-saving mode. When encountering a slope, the controller instantly becomes a strong man.
No need for maintenance for ten years.
The bearing sealing ring is the same as that of a submarine. Even when it gets wet in the rain, it can still run smoothly.
Master Wang from the Old Street Auto Repair Shop tested it: When installed on the elderly Electric tricycle he modified, the original charging frequency was once every three days. Now it can last for five days. The most amazing thing is that when carrying 300 kilograms of frozen goods and climbing the 45-degree slope of the building materials market, it no longer needs to get off and push. Maintenance Tips
▷ Clean the motor cooling gap with an old toothbrush every month
▷ Apply some vaseline to the connector to prevent oxidation
▷ Don't spray car wash foam onto the motor
