Applications of Axial Flux Motor Technology

The flux path of an axial flux motor (disc motor) is different from that of an ordinary radial motor. The air gap is planar. The direction of the air gap magnetic field is parallel to the direction of the motor axis. The core technical advantage of the axial flux motor is that the rotating rotor is structurally located on the side of the stator. Rather than inside the stator, the rotor has a larger diameter.

Torque = force × radius, so higher torque output can be obtained under the same force. This means that higher torque output can be obtained while providing the same permanent magnet material and copper wire material.

Generally, new axial flux motors can increase torque density by more than 30% compared to traditional radial motors.

Axial Flux Motor Key Technology


According to the number of stators and rotors, their relative positions, and the classification of the main magnetic circuit, the basic topology can be divided into four types, namely single stator and single rotor structure, double stator and single rotor structure, single stator and double rotor structure and multi-disc structure.

The automotive electric drive industry focuses on using two structural topologies: double stator single rotor and single stator double rotor.

Motor 3D design

The flux path of traditional radial motor follows nonlinear 2D path, while the axial flux motor is 3D path.

Therefore, the differences between the two must be taken into consideration when performing performance simulation design. Models should be built according to their respective characteristics to improve the accuracy of the model.

For new flux motors, 3D multi-physics joint simulation and multi-objective comprehensive optimization can be used to design electromagnetic solutions. Continuously improve the computational efficiency of axial flux motor design and improve accurate virtual modeling and simulation capabilities.

New material technology

For heat dissipation and cooling, high-strength and high thermal conductivity epoxy resin potting filling materials are developed. To increase the heat dissipation capacity of the motor body and prevent the permanent magnet from demagnetizing at high temperatures.

Develop sheet molding compound (SMC) composite materials, amorphous alloy materials, and oriented silicon steel with high magnetic permeability and low loss for the stator and rotor lamination cores. SMC materials are easy to form and have simple heat treatment processes, making them suitable for mass production.

A carbon fiber winding and fixation strengthening process was developed to meet the needs of a high-strength stator and rotor. In order to cope with the physical characteristics of the permanent magnet itself which has poor tensile strength.

Manufacturing process

For stator winding, we develop rectangular cross-section copper wire, spiral concentrated winding, and multi-pole continuous winding technology.

Develop low-loss segmented fixed installation and magnetic pole shoe demagnetization protection processes for permanent magnets.

Develop yokeless segmented armature splicing, boltless fixing with end covers, and powder metallurgy manufacturing processes for the stator core.

In response to batch production needs, we develop automated stator and rotor assembly technology, automated production of flat conductor forming coils, and flexible automated production line technology.

Applications Of Axial Flux Motor

In the field of automotive electric drives using permanent magnet synchronous motors or induction motors, traditional radial flux motors are being extensively developed for weight and cost optimization.

However, there is very limited room for further improvements in technology levels. Therefore, moving to a completely different motor type may be a good alternative.

Because the axial flux motor has the technical characteristics of compact structure, flat and ultra-thin, small size, lightweight, and high power density.

Many developers have worked hard to improve this technology in the past decade. Make it gradually suitable for electric motorcycles and airport cranes. new application scenarios such as cabins, cargo trucks, electric vehicles, and even electric aircraft.

How does axial flux technology differ from traditional radial flux motors

Axial flux technology differs from traditional radial flux motors primarily in its rotor-stator configuration. In axial flux motors, the magnetic flux travels parallel to the motor’s axis, allowing for a more compact and efficient design.

This contrasts with radial flux motors, where the flux moves radially from the center outward. The axial configuration results in a higher power density and more efficient use of space, making axial flux motors well-suited for various applications demanding compactness and enhanced performance.
