Axial flux electric motor lamination design and manufacture capabilities
Disk motor stator lamination process
The production of axial flux motor stator lamination is essentially different from the traditional stator stacks core.
The lamination direction of the traditional stator using an appropriate lamination stamping process is to stamp or cut a single piece of the same shape, and lamination bonding, interlock, or welding from the axial direction to achieve the parameters and height required to design the product.
The disc stator uses special stamping and rolling integrated equipment, stamps the groove through a dedicated stamping die, and uses a servo synchronous control system to accurately control the stamping frequency and rolling machine speed to ensure consistent alignment of the product diameter from the inner to outer.
Double-sided punching axial flux stator process
However, if the stator has teeth on both planes, then it should How to deal with it? There are two situations:
The two teeth of the stator are in a parallel position: You only need to design a punch when designing the mold, and the two teeth are stamped simultaneously.
The two teeth of the stator are misaligned: Since the distance between the two teeth increases as the rolling radius increases, the traditional mold can no longer meet the requirements.
Dynamic stamping die design is required, that is, the punch is in a moving state, and the stamping time and cycle are precisely controlled by the computer to achieve the required stamping results.
Process of Self-bonding silicon steel to produce stators
The process begins with precision cutting silicon steel strips to the designed width. This step ensures uniformity and accuracy in the stator’s dimensions.
A stamping mold tooling should be designed to stamp the coil shape.
This punching machine has been designed for axial flux stator lamination and it can scroll the stators to the dimensions of Desired ID and OD and ensure each slot has the same position from different layers; normally it can realize +/-0.5mm tolerances for OD and ID Dimension.
To fixate the lamination coil in its designated shape, spot welding is employed on the starting and ending strips.
Stator dimension correction and align laminations for all slots and two plates.
The back plate surface of the stator is subjected to bonding or laser welding.
Depending on the design and application, assembly screw holes may be created at this stage.
To achieve optimal flatness and surface finish, surface grinding may be employed. This step enhances the stator’s overall quality and performance, ensuring that it meets the stringent standards required for electromagnetic applications.
Disc motor stator lamination stacks polygon correction
The production process of disc motor stator is stamping + winding. Through precision system control and synchronization, the number of teeth and lamination thickness are determined by operating system settings.
In fact, when the winding is in progress, the material of the stator teeth has been sheared by stamping, so it cannot be wound in a circle according to the theoretical design, but will become a polygon.
The side length of the polygon is directly related to the size of the stator and the number of teeth. This polygon will be more obvious when the outer diameter of the stator is larger (more than 200mm), or when the number of teeth is less than 24.
Through a unique technical solution, Motorneo can realize polygonal arc correction, so that all stator outer diameters approach the theoretical arc shape.
Axial Flux Stator Winding for Electric Motor
Axial flux stator winding employs innovative techniques like flat embedded winding and vertical embedded winding to optimize the efficiency of electric motors.
In the context of flat embedded winding, conductors are intricately laid out in a flat, planar fashion, offering improved thermal performance and allowing for a more compact motor design. This configuration enhances heat dissipation and facilitates better use of available space.
On the other hand, vertical embedded winding involves strategically placing conductors in a vertical arrangement, further contributing to space optimization.
Both winding methods aim to enhance the magnetic flux distribution within the stator, ultimately leading to increased motor efficiency.

axial flux electric Motor Core FAQs
Commonly used materials in axial flux motor stator laminations include electrical steels, such as silicon steel or grain-oriented electrical steel (GOES). These materials possess high magnetic permeability, minimizing energy losses due to eddy currents.
An axial flux motor differs from a radial flux motor primarily in the direction of the magnetic flux within the motor. In an axial flux motor, the magnetic flux flows parallel to the motor’s axis, moving from one side of the motor to the other.
This is in contrast to a radial flux motor, where the magnetic flux travels radially, moving from the center of the motor to its outer edges.
The axial flux motor design often results in a more compact and lightweight motor with specific advantages in terms of efficiency, power density, and cooling capabilities compared to radial flux motors.
Yes, we often customize the design and dimensions of axial flux motor stator laminations. Which meet the specific requirements of different applications, such as axial flux motors of electric vehicles, industrial machinery, or renewable energy systems.
