In drone motor lamination stacks prototyping, we employ both laser-cutting and wire-cutting processes to manufacture intricate laminations.

Laser cutting employs a focused laser beam to precisely slice through materials, ensuring clean and accurate edges in the lamination stacks. This method excels in creating intricate patterns and shapes with minimal material wastage.

On the other hand, wire cutting involves using a wire electrode to shape the laminations, allowing for the production of more complex and detailed designs.

With a lead time of 7 – 15 days, our efficient and agile prototype development underscores our dedication to delivering high-quality drone components that meet the demands of contemporary technology.

The progressive die stamping manufacturing process involves using a high-speed punching press for a series of consecutive stamping operations performed on a silicon steel metal strip, gradually forming the desired shape of the laminations.

Progressive stamping ensures remarkable consistency and accuracy in each lamination, resulting in enhanced efficiency and performance of the drone motors.

This method is particularly advantageous for high-volume production, as it allows for the rapid creation of intricate designs with minimal material waste.

In addition, our progressive stamping press punches segmented stator laminations to meet clients’ needs.

Drone Motor Lamination Bonding

glue bonding laminations

This process involves bonding individual laminations, typically made of silicon steel, to create the motor’s core.

Employing glue dot bonding, we ensure secure adhesion between laminations, enhancing structural integrity. This method involves the precise application of adhesive dots, creating a robust bond while minimizing excess glue.

Additionally, our self-bonding process leverages the inherent adhesive of certain electrical steel laminations, promoting a seamless fusion without external adhesives. This approach not only streamlines production but also contributes to the overall durability of the motor components.

During stamping, strategic interlock points are created on the motor laminations, allowing them to seamlessly stack into cores.

This interlock point, whether in a rectangle point or round circular shape point, facilitates the self-interlock of the lamination from the stator and rotor core.

Progressive stamping uses an interlock process to enhance efficiency, saving time and costs during assembly. The resulting precise and secure fit between laminations promotes structural integrity, minimizing electromagnetic losses, heat generation, and noise.

In this method, the iron core of the motor undergoes a coating process using epoxy powder. This coating serves as a protective layer, providing resistance against corrosion, abrasion, and environmental factors.

The epoxy powder coating not only safeguards the motor from external elements but also improves its insulation properties.

This process ensures longevity and reliability in the drone motor’s operation, even in challenging conditions.

Additionally, the epoxy coating contributes to thermal stability, preventing overheating during prolonged usage.

Motor stator core windings are essential components that generate the magnetic field necessary for drone motor operation.

The process involves carefully winding insulated copper wire around the stator core, creating coils that interact with the rotor to produce electromagnetic forces.

Precision is key to achieving desired electrical characteristics, and we employ automated winding machines for consistency and efficiency.

In addition, we will provide manual winding according to customer requirements, skilled technicians can flexibly handle complex winding patterns and custom designs.
