Hardcore technology builds a reliable foundation and adapts to the entire scene to empower heavy-duty working conditions

1、 Self developed core motor technology, with comprehensive performance leading the industry's conventional products

Naiweide Motor uses two self-developed processes, permanent magnet synchronization and flat wire winding, as its technical core, achieving performance breakthroughs in three dimensions: power output, energy saving and consumption reduction, and service life.

Firstly, high torque low-temperature starting, worry free adaptation to the entire environment. All products in the series are equipped with an independent permanent magnet synchronous structure, which increases power density by 25% compared to traditional ordinary motors. The instantaneous starting torque is abundant and the response speed is fast. It can achieve one-time stable ignition in extremely cold environments of -40 ℃ and at an altitude of 5000 meters, completely solving the industry pain point of difficult starting of winter and high-altitude equipment.

Secondly, efficient and energy-saving design effectively reduces the fuel consumption of the entire vehicle during operation. The basic power generation efficiency of the generator can reach over 82%, an increase of 10 to 15 percentage points compared to traditional products; The ISG integrated start stop power generation unit under its umbrella can recover 30% of braking energy, save 15% -20% in comprehensive fuel consumption after installation in construction machinery, save 8% -12% in fuel consumption during long-distance transportation of heavy trucks, and significantly reduce fuel expenses in long-term operation.

Thirdly, the brushless long-life structure reduces high-frequency maintenance losses. The high-end models adopt a brushless architecture, eliminating consumable components such as carbon brushes and slip rings, and increasing the average start stop life of the equipment from the traditional 50000 times to 300000 to 500000 times; The basic thickened wear-resistant carbon brush is paired with a reinforced one-way clutch, which is resistant to gear impact and less prone to tooth breakage, significantly reducing the frequency of maintenance and replacement.

Fourthly, lightweight and efficient heat dissipation, capable of withstanding sustained high temperatures in the cabin. The product adopts Hairpin flat wire winding with low wind resistance heat dissipation channel, which can withstand high temperature of 120 ℃ in the cabin for a long time; The carbon fiber rotor paired with a lightweight aluminum alloy shell reduces the weight of the entire machine by 15% -30%, making it more adaptable for installation in narrow cabins and reducing equipment load pressure.

2、 Heavy duty protective structure, suitable for harsh and complex working conditions in mines and construction sites

Engineering vehicles and forklifts shuttle in dusty, muddy, and strong vibration environments all year round, and water ingress, ash ingress, and insulation failure are common causes of motor failures. Naiweide strengthens the overall protection and earthquake resistant structure, creating all-weather stable operation capability.

The dust and water resistance level of the whole machine reaches IP67 standard, and the sealing structure of the whole machine is tight. It is not easy for water to enter and accumulate dust during operations in open-pit mines and muddy construction sites, avoiding coil short circuits and burnout faults from the root; The shell, bearings, and transmission gears are all reinforced with heavy-duty technology, combined with aviation grade high-temperature resistant insulation materials, to cope with continuous severe shaking of excavators and loaders, and the insulation performance is stable and does not deteriorate for a long time.

The performance of power supply stabilization is also outstanding. The generator is equipped with a high-precision electronic regulator, and the 12V and 24V dual voltage outputs have minimal fluctuations. When multiple load devices such as car lights, air conditioning, and on-board monitoring are turned on at idle and heavy loads, the voltage is stable and does not trip, effectively protecting the battery and preventing power loss during long-distance and long-term operations.

3、 Complete product matrix coverage, supporting standardized supply and non-standard customization
