The segmented stator lamination prototyping process integrates cutting-edge technologies like laser cutting and wire cutting to craft precise motor components.

Our lamination prototype materials such as silicon steel and amorphous metal alloys, ensure optimal performance and durability in electric motors.

With a lead time of about 7-15 days, engineers can swiftly iterate designs and evaluate prototypes for efficiency and effectiveness. Laser cutting enables intricate patterns with minimal material wastage, while wire cutting ensures accuracy in shaping complex geometries.

This streamlined process not only accelerates development but also ensures that final products meet stringent industry standards.

Our stator and rotor lamination punching process employs high-speed progressive stamping techniques to craft intricate segmented stator stacks with precision and efficiency. Progressive stamping is cost-effective for large-scale production of stators.

These core laminations are typically made of materials like silicon steel due to their magnetic properties. This process begins with the feeding of silicon steel coils into a high-speed stamping press equipped with progressive dies.

The dies progressively shape and cut the laminations with precision, ensuring uniformity and accuracy in size and shape. High-quality segmented stator laminations are preferred for their efficiency by minimizing eddy current losses and improving overall motor performance and efficiency.

Our segmented motor lamination bonding process offers two innovative techniques: glue dot bonding and self-bonding.

Glue dot bonding uses an automation dot adhesive machine to dispense adhesive dots on a segmented laminated sheet, ensuring secure attachment while maintaining flexibility for assembly adjustments.

On the other hand, self-bonding relies on the coated bonding varnish of the laminations to form a tight bond without additional adhesives, simplifying assembly and enhancing structural integrity.

Both methods provide efficient solutions for constructing segmented motor cores, catering to diverse application requirements.

Segmented core lamination stacking employs the dovetail slot method, integrating interlocking slots for enhanced structural integrity.

The dovetail slots create a tight interlocking mechanism, enhancing stability and resistance to mechanical stresses.

Additionally, we also offer welding that further reinforces the connections, providing robust support for the motor core.

This approach facilitates efficient assembly while maintaining strict tolerances, resulting in reliable performance across various industrial applications.

The segmented stator plastic overmolding insulation process involves encapsulating segmented stator laminations with a durable plastic material to enhance insulation and protection.

This technique plays a crucial role in enhancing electrical isolation between laminations, minimizing the risk of short circuits, and enhancing motor reliability.

Our stator injection molding process utilizes BMC, PA, PPS, and PET insulating material to precisely encapsulate each segment, forming a seamless protective layer.

This insulation method offers excellent resistance to environmental factors such as moisture and vibration, extending the lifespan of electric motors in various applications.

Our epoxy powder coating insulation process involves applying a durable epoxy resin coating onto segmented laminations to enhance insulation and protection.

This method ensures a uniform and resilient insulation layer, shielding the laminations from environmental factors such as moisture, chemicals, and abrasion.

Our epoxy powder coating process utilizes electrostatic application techniques followed by curing at high temperatures, resulting in a smooth and robust finish.

This coating not only improves electrical insulation but also enhances the mechanical strength and corrosion resistance of the motor core.
