Accelerate the cultivation and opening of scenarios, and empower the value transformation of scenarios with axial magneto-driven systems

Recently, the official account of "Zhejiang Development and Reform Commission" released "New Energy-saving Technologies, New Products, New Equipment: Axial Flux Drive System, New Energy Conservation and Emission Reduction Plan", comprehensively elaborating on the technical principles, application scenarios and application effects of axial flux motors.

I. Technical Principles

Axial flux motor is a new type of structural motor and a cutting-edge innovative product in the field of motors. This motor product has a flat disc appearance, so it is also called a disc motor. The difference from conventional motors is that the cross-linking magnetic field direction of the stator and rotor in axial flux motors is axial. This principle determines that the space utilization rate of axial flux motors is significantly higher than that of conventional motors, and they have the characteristics of lightweight, high efficiency and wide high-efficiency zone.

Panhu Power is a globally leading high-tech innovation enterprise in the field of axial flux motors. Through original and pioneering scientific and technological research and innovation, it has currently achieved "five firsts" :

1. Application First: The world's first and currently the only one to achieve over 10,000 market applications of axial flux motors.

2. First: The number of sub-sectors has consistently ranked first in the world.

3. First in mass production: Established the world's first mass production line for axial flux motors;

4. First in technological diversity: The only one in the industry that covers the three major technical routes of ICS/ICD/PCB;

5. Product maturity first: Covering all power segments from 63W to 900kW, the product maturity is the highest.

Ii. Application Scenarios and Effects

Hub axial flux motors, with their inherent advantages of being flat and compact, having high power density and high torque density, are demonstrating strong application potential and obvious differentiated value in numerous field scenarios.

In the field of new energy buses, the hub axial flux motor distributed wheel-side drive system - the "Metro Bus" solution has been installed on over 10,000 buses. Its unique configuration has achieved a "fully flat and low floor" inside the vehicle, significantly expanding the effective passenger space. The passenger capacity of a 7-meter "Metro bus" has reached the level of a regular 8-meter new energy bus. The carrying capacity of the 8-meter "metro bus" is comparable to that of the 10-meter ordinary new energy bus, "replacing the larger model with the smaller one".

In the field of new energy heavy-duty trucks, the integrated electric drive axle equipped with hub axial flux motors has achieved "ten technological evolutions", realizing differentiated value upgrades in various dimensions such as lightweight, power performance, economy and reliability. Among them, the entire bridge adopts an integrated design, reducing weight by approximately 400kg, increasing transmission efficiency by 10.8%. Under the same working effect, the motor speed is reduced by 1000rpm, and the oil stirring loss is decreased by 6%. After nearly a year of verification under heavy-load compound working conditions, the average monthly energy consumption of the 49-ton traction fleet for the coal transportation dedicated line has dropped to 1.2 kilowatt-hours per kilometer, which is 0.2 to 0.3 kilowatt-hours per kilometer lower than that of similar products in the market.

In the field of construction machinery, the hub axial flux motor is smaller in size. In the power system transformation of equipment such as loaders and excavators, it can quickly achieve electrification upgrade without large-scale reconstruction of the original chassis, effectively reducing the transformation cost. Its high torque density characteristic ensures stable power output of the equipment during heavy-load operations, maintaining efficient operation even under complex working conditions, significantly enhancing operational efficiency while reducing carbon emissions.

In the field of new energy two-wheelers, the lightweight advantage of this motor effectively increases the vehicle's driving range, while the compact structural design provides more space for optimizing the body shape. In the fields of ships and new energy agricultural machinery, axial flux motors also provide strong support for the electrification transformation of related equipment with their reliable performance and adaptability.

In the field of industrial energy conservation, hub axial flux motors can be adapted to various general machinery such as fans and pumps. Through precise speed regulation and efficient energy conversion, they significantly reduce the energy consumption of equipment operation, helping industrial enterprises achieve their energy conservation and consumption reduction goals.

The hub axial flux motor, when combined with a high-efficiency water pump hydraulic model, wear-resistant coating, high-efficiency and low-wear impeller and other comprehensive high-efficiency pump integrated solutions, achieves an overall energy-saving effect of 10% to 30%. Take the thermal power transformation as an example. After the motor transformation of some process equipment, the motor efficiency is improved, the pump set efficiency is enhanced, and the energy-saving rate can reach up to 41.1% at most.

In the field of general-purpose fans, the hub axial flux motor enables direct motor connection without increasing the spatial dimensions, eliminating the original belt drive and effectively enhancing the efficiency of the transmission chain. Combined with the high-efficiency three-dimensional flow blades and the precise matching of the high-efficiency zone of the impeller with the normal operating zone of the working conditions, a comprehensive energy-saving effect of 10% to 45% can be achieved.

In a broader range of application scenarios and fields, Panhu adheres to the product development concept of "creating differentiated value upgrades for users", takes technological innovation as the core driving force, continuously deepens collaborative cooperation with partners in the upstream and downstream of the industrial chain, and constantly expands the application boundaries of axial flux motors in more emerging fields, contributing more innovative achievements to the high-quality development of the global electric drive industry.
