After four years, the top exhibition in the global construction machinery industry - BAUMA CHINA 2024 (BAUMA CHINA 2024, hereinafter referred to as "BAUMA") returns with a bang, "Chasing the light and meeting, all things are radiant", more than 3,400 exhibitors from 32 countries and regions around the world will gather in Shanghai, and tens of thousands of innovative products and cutting-edge technologies will be re-launched, with an unprecedented scale.

Under the wave of electrification, the construction machinery industry, like the development of new energy vehicles before, is also paying close attention to the development and application of core "three electric" technologies such as batteries, electric drives, and electronic controls. At this year's BAUMA, the axial flux electric drive system with its small size, light weight, and high efficiency has become a popular choice and is used in a variety of construction machinery and equipment, providing core power for the development of the industry's electrification technology.

Compared with traditional drive motors of the same power, the volume and weight of the axial flux motor are reduced by about 50%, which means that it can "provide twice the power output in the same layout space" to meet the high torque and high power requirements of engineering machinery and equipment; at the same time, the efficiency MAP of PanGood’s axial flux motor reaches double 90, which can provide users with greater energy-saving and cost-reduction value.

Efficient cost reduction | Axial flux motor "oil to electricity", loader earns more than 1 million in three years!

Data confirms that loaders have become the vanguard of electrification of construction machinery. According to data from the China Construction Machinery Industry Association, from January to October this year, my country sold a total of 9,361 electric loaders, with a penetration rate of 10.38%, a year-on-year increase of 269.3%, and a penetration rate of about 3.5 times that of the same period last year.

Compared with fuel-powered models, electric loaders have higher production efficiency, lower operating costs, and can carry more materials. The axial flux electric drive system can achieve more than 90% working efficiency in more than 90% of working conditions, and the cost saving effect is better. For the "oil-to-electric" popular in the loader field, the axial flux motor solution is adopted. The outer transition flange of the motor is directly connected to the torque converter. There is no need to change the original engine compartment or add additional suspension points. The overall change is smaller and the transformation cycle is shorter. Under normal working conditions, a 5-ton loader can save about 1 million yuan in overall use costs in three years after "oil-to-electric", and it can also greatly enhance the service life of the engine and the vehicle.

At present, PanGood’s axial flux electric drive system has been applied in multiple regions and multiple products in the field of loaders. After a customer in Fujian Province used PanGood’s solution to convert a 5-ton loader from oil to electricity and tested and verified it, he immediately placed an order for three more units. "After using PanGood’s axial flux motor to convert oil to electricity, we saved a lot of money compared to the previous fuel loader!"

All-round all-wheel drive | Axial flux electric drive accelerates the process of new energy excavators

In the field of excavators, the axial flux electric drive system can be widely used in various technical routes such as charging and swapping integrated excavators, diesel range extenders, methanol range extenders, and hybrid power.

Applied to charging and swapping integrated excavators, the characteristics and advantages of "axial flux motors are 50% smaller than radial flux motors of the same power", making them more flexible in overall layout design, with more room for spare space, and with the characteristics of rapid torque release, faster response speed, better control accuracy, and higher operating efficiency, reducing maintenance costs by more than 30%;

In extended-range and hybrid excavators, "PanGood’s axial flux motor can achieve more than 90% working efficiency in more than 90% of the working conditions", and can achieve the superposition effect of the high-efficiency range of the engine and generator under more working conditions, achieving a higher oil-to-electricity conversion ratio. At the same time, it has good adaptability and outstanding performance in extreme environments such as high temperature, severe cold, and plateau.

Stable and reliable | Axial flux electric drive mining trucks, people stop and keep running, three years of stable operation

As early as several years ago, PanGood has been exploring the application of axial flux electric drive in the field of new energy mining trucks, and has applied and practiced products in mines in East China, Central China, North China, Northwest China and other regions. At this BAUMA exhibition, mining truck models using axial flux electric drive began to spread.

Compared with radial flux motors, PanGood’s axial flux motors have greater starting torque and can output high power and torque at low speeds. Data shows that when using the same platform controller, the continuous torque of PanGood’s axial flux motors is increased by 11%, and the continuous power is increased by 16%. In addition, they have the characteristics of rapid torque release, faster response speed, more precise control, and stronger climbing and escape capabilities.

The person in charge of a mining fleet in central China said, "We have been using PanGood’s axial flux electric drive mining trucks for more than three years. We have been running them in shifts without stopping. We have hardly ever heard of a vehicle stopping due to a motor failure. The reliability and stability are very strong! We use this batch of vehicles to build an unmanned fleet, and the performance is much better than ordinary vehicles."

Small but powerful | Axial magnetic flux electric drive accelerates concrete mixer trucks towards a green future

With the continuous advancement of the national "dual carbon" strategy, and driven by the consistent requirements of production and use for environmental protection and economy, the electrification trend of concrete mixer trucks will become more obvious. Whether it is a fuel mixer truck or a pure electric mixer truck, the axial magnetic flux electric drive system is becoming the mainstream configuration of the concrete mixer truck.

For fuel mixer trucks, the electric drive installed on the axial magnetic flux can completely replace the traditional hydraulic device and realize the separation of engine power and mixing tank power. Whether during vehicle loading, unloading, or normal driving, the rotational power of the mixing tank is entirely provided by the system's own power battery compartment, which no longer occupies engine power. While the vehicle is idling and waiting, the tank will not be affected when the vehicle stalls. Rotation does not affect the use of the air conditioner, thus significantly reducing fuel consumption; at the same time, while the vehicle is driving, the system automatically collects the engine's excess power to charge the battery;

For electric mixers, PanGood’s axial flux motor directly drives the mixing tank, eliminating the need for an intermediate transmission mechanism, greatly improving the overall system efficiency and reducing energy loss; the electric drive system weighs only 31 kilograms, and its cantilever is shorter, and The link of the top-mounted tank is more stable and has less impact on the tank; the efficiency MAP double 90 can maintain efficient operation under various working conditions and significantly reduce energy consumption.

At present, concrete mixer trucks equipped with PanGood’s axial magnetic flux electric drive upper system have been put into mass operation in many regions and cities across the country, demonstrating a strong market influence, bringing more efficient, energy-saving and environmentally friendly production methods to various mixer truck users, and also injecting strong and innovative momentum into the green and low-carbon development of the commercial concrete industry.

Core engine | Axial flux electric drive, shaping the new benchmark of road machinery electrification

Road construction machinery models such as rollers, milling machines, and pavers have more diversified and personalized requirements for motors and electric drives in the process of accelerating electrification.

For example, the steel wheel roller, which is essential in road construction, has a core component, the steel wheel, which is both a working wheel and a traveling wheel. The drive motor needs to be able to output strong torque and force, and the axial size of the motor must not exceed the width of the vehicle. In this case, the axial flux motor is obviously more suitable than the radial flux motor.

Taking the ICS188K motor of PanGood as an example, its peak output power reaches 188kW and its peak output torque reaches 800N·m, but the axial dimension of the motor is only 164.5mm, which is more than 2/3 shorter than the radial permanent magnet synchronous motor with the same power. At the same time, its own weight is only 65kg, and the high efficiency range is also larger, and the performance in energy consumption and endurance will be better.

The situation faced by milling machines and pavers is similar to that of road rollers. When using direct motor drive to meet the needs of vehicle travel and synchronous operation, the motor power and output torque are required to be strong enough, but the axial size of the drive unit cannot exceed the width of the vehicle. The layout space is very limited, and the small and efficient axial flux motor is almost a must.

At this year's BAUMA exhibition, several engineering machinery manufacturers such as XCMG and Sany adopted axial flux motors as the core drive for their electrified road machinery models, providing a good reference and reference for the development of this field.

Super Saving | Axial Flux Range Extender Generator, Make Every Drop of Oil Generate More Electricity

Thanks to the typical advantages and characteristics of the axial flux motor, such as small size, light weight and high efficiency, as well as its disc-like design in appearance, the axial flux motor has a more obvious advantage than the traditional radial flux motor in the field of range extenders.

The axial flux motor can fully match the engine flywheel housing, the axial size is reduced by more than 2/3, and the overall structure is more compact and lightweight; in addition, the efficiency MAP of the disc-hub axial flux motor reaches double 90, and the working efficiency can reach more than 90% under more than 90% working conditions, which is more conducive to the superposition effect of the high-efficiency zone of the engine and the range extender generator, so that every drop of oil can generate more electricity.

At this year's BAUMA exhibition, many manufacturers, including XCMG, a leading enterprise in the construction machinery industry, displayed range extenders using PanGood’s axial flux motors, covering multiple power ranges of 100kW-250kW and multiple specifications and models, which can meet the application needs of more products and more working conditions, and provide users with more suitable customized solutions.

In addition, at the exhibition site, the application of axial flux electric drive solutions in various complete vehicles and parts products such as concrete mixer trucks, crawler chassis, cranes, and wheel hub drive systems is increasing, and the attention is also increasing.

The wave of electrification of construction machinery is unstoppable, and the competitiveness of domestic technology is increasing. This year's BAUMA exhibition has once again confirmed this view. As a representative of "new quality productivity" in the field of motors and electric drives, PanGood, based on the application of axial flux motors, provides innovative solutions with disruptive value upgrades for various products and scenarios in the field of construction machinery, providing a stronger driving force for industrial innovation and development.

PanGood looks forward to working with partners from all walks of life to jointly promote the technological revolution in the electric drive industry.
