Axial Flux Motors: A Key to the Electrification of Agricultural Machinery

Axial flux motors, known for their lightweight design, compact dimensions, and extensive high-efficiency range, are ideally suited for agricultural machinery applications. Compared to conventional radial flux motors, these motors are 50% lighter and have over 50% reduction in axial length at equivalent power and torque densities. The innovative, efficient, and compact nature of axial flux motors and electric drive systems has provided a significant impetus to the technological advancement of agricultural machinery.

Applications of Axial Flux Motors in Electric Tractors

Zhongke Yuandongli has introduced two new high-horsepower intelligent electric tractors: the Wantu 2004ET and Wantu 2604ET. These models are powered by axial flux motors, with the Wantu 2604ET featuring our KICS450 axial flux motor, which boasts a peak single motor power output of 450kW, capable of handling heavy-duty operations. This motor's volume power density has been significantly enhanced, and its axial length reduced by approximately 50%, offering greater flexibility in vehicle design and spatial arrangement.

Advantages of Intelligent Electric Tractors Over Traditional Tractors

Energy Efficiency and Environmental Protection: Intelligent electric tractors, powered by electricity, offer lower emissions and higher energy efficiency compared to traditional diesel tractors. They can achieve zero emissions, thereby mitigating the environmental impact of agricultural operations.

Intelligence and Automation: These tractors integrate advanced intelligent and automated technologies, including automatic navigation and unmanned driving, reducing reliance on driver skills and decreasing labor intensity and operational challenges. Intelligent systems enable unified planning and precise control over land plots, enhancing land utilization and production quality.

Cab Comfort and Safety: The cab design of intelligent electric tractors prioritizes safety, comfort, and reliability, equipped with a fresh air purification system, automatic climate control, a 360-degrees lighting system, and an expansive field of view, ensuring optimal working conditions around the clock.

Battery System and High-Voltage Electronic Control System: Intelligent electric tractors feature a high-reliability integrated battery pack specifically developed for agricultural machinery, with the capability for ultra-fast charging and discharging, allowing for a full charge within an hour. The highly integrated 10-in-1 multifunctional intelligent electronic control unit ensures the system operates intelligently and efficiently.

Electronic Human-Machine Interaction and Manipulation: The driving and agricultural implement control systems are fully electronically controlled, eliminating traditional mechanical gear levers and cables in favor of an integrated multifunctional armrest, simplifying driving and operational tasks with touch controls.

Power and Electric Transmission System: Equipped with a self-developed heavy-duty high-torque motor with superior transient response capabilities, these tractors are matched with a self-developed automatic transmission, enabling functions such as variable speed change and automatic shifting between different sections.

Multi-Functional Connection System: The rear three-point suspension system with large lifting force supports comprehensive force and position adjustment functions, and is equipped with a 3-way electronically controlled flow remote valve, with a peak flow rate of the hydraulic system pump exceeding 100L/min, meeting the needs of high-flow implements.

Endurance and Charging Capacity: Intelligent electric tractors have extended battery life, capable of achieving 1-hour rapid charging (from 15% to 90% battery level).

Operational Efficiency and Energy Consumption Cost: Actual measurement data indicates that intelligent electric tractors have increased operational efficiency by over 30% compared to traditional agricultural machinery, while reducing energy consumption costs by 80%.

Through these enhancements, intelligent electric tractors offer significant advantages in improving agricultural production efficiency, reducing operational costs, and enhancing operator comfort and safety, representing the direction of agricultural mechanization and modernization.

Applicability of Electric Tractors in Agricultural Operations

The powerful output and efficient transmission system of smart electric tractors make cultivation tasks easier and more efficient. Electric tractors are suitable for sowing operations and can meet the speed requirements of various machines. Smart electric tractors can be equipped with gardening machinery, such as fertilizer spreaders, to assist in fertilization tasks. Suitable for harvesting operations, these tractors meet the operational requirements across different seasons and crop types. Smart electric tractors can also be fitted with pruning equipment for gardening tasks. Under rotary tillage conditions, electric tractors demonstrate high average efficiency of the drive motor and sufficient endurance time. The intelligent electric tractors have proven effective in pastures and fields, capable of handling various complex terrains and operational requirements.

Applications of Axial Flux Motors As Range Extender

In addition to electric tractors, axial flux motors are also utilized in agricultural machinery range extenders, such as the 8Y range extender co-developed by Shanghai Diesel Power and Panhu Power. Comprising an engine and an axial flux generator, this range extender boasts a high power generation efficiency of 4.35kWh/L.

The primary function of a range extender is to convert alternative forms of energy, like gasoline or natural gas, into electrical energy for agricultural machinery. This conversion typically involves generating power through the combustion of fuel in an internal combustion engine, which then drives a generator to produce electricity. The electrical energy produced by the range extender can either directly power the agricultural machinery's motor or be stored in a battery for later use, extending the operational time of the machinery when battery power is low.

In summary, the application of axial flux motors in agricultural machinery is expanding, offering new power solutions for agricultural mechanization and modernization with their high power density, efficiency, and compact design. As technology advances and costs decrease, the use of axial flux motors in agricultural machinery is expected to grow further.
