Lamination Stamping For DC Motor

progressive stamping for motor lamination

With 10 years of experience in the industry, we employ cutting-edge DC motor rotors and stator lamination stamping techniques such as progressive stamping, compound stamping, and rotary notching.

The progressive die stamping process efficiently creates intricate shapes and features on silicon steel strips, ensuring precise dimensions and consistent quality for laminations. The progressive stamping technique enhances production speed, making it a cost-effective solution for high-volume DC motor manufacturing.

Compound stamping for DC motor laminations integrates multiple stamping operations into a single die set, streamlining the manufacturing process. This technique combines efficiency with precision, allowing for the creation of intricate shapes and features cost-effectively. Compound stamping is ideal for medium and large production of motor core laminations.

The rotary notching process for DC motor stator or rotor laminates is a single-operation notching lamination. Utilizing advanced servo control systems, our rotary notching machine creates seamless notches, reducing material waste and boosting motor performance. This technology is an economical choice for low-volume production or prototyping.

At our facility, we prioritize precision and reliability through two advanced lamination bonding techniques: glue dot bonding and self-bonding.

Glue dot bonding involves applying adhesive dots strategically to secure laminations, ensuring a uniform and durable bond. This method offers enhanced structural integrity and thermal stability.

On the other hand, our self-bonding technology utilizes the electrical steel materials coated with bonding varnish without additional adhesives. This approach minimizes the risk of delamination and enhances the motor’s overall durability.

By offering both options, we cater to diverse motor specifications, guaranteeing high-quality and customized solutions for our clients.

During this procedure, laminations, typically made of silicon steel, are meticulously stacked to form the motor’s core. The careful arrangement of these laminations is vital to reduce energy losses caused by eddy currents and enhance magnetic performance.

We offer interlocking, laser welding, TIG welding, MIG welding, riveting, cleating, and gluing methods to complete core assembly. Our automated machinery equipment has accurate alignment and tight tolerances during stacking.

Advanced techniques, such as robotics and automated assembly lines, contribute to consistent and high-quality motor core lamination stacking for diverse applications.

After stacking the laminations, an injection molding process is employed to encapsulate the stator core with insulation material(thermoplastics). This insulation acts as a barrier, preventing electrical contact between laminations and reducing the risk of eddy current losses.

The injection molding technique ensures uniform insulation distribution, improving the motor’s thermal performance and reliability. It also enhances resistance to environmental factors such as moisture and contaminants.

This advanced process not only reinforces insulation but also contributes to the longevity and efficiency of DC motors, making them well-suited for a wide range of applications.

Our epoxy powder coating insulation process involves applying a thin, uniform layer of epoxy powder onto the laminations, creating a durable and protective insulation barrier.

The coating serves to prevent electrical conductivity between laminations, reducing eddy current losses and enhancing the motor’s efficiency.

Epoxy’s excellent dielectric properties also contribute to increased insulation resistance, minimizing the risk of electrical failures. The process involves a meticulous application and curing procedure, ensuring a uniform and smooth finish.

This coating method not only safeguards against electrical issues but also provides resistance to environmental factors, such as moisture and chemicals, further prolonging the lifespan of the DC motor.

The DC motor stator winding process involves winding insulated copper wire around the stator core’s teeth to create electromagnetic coils.

The winding pattern and configuration play a pivotal role in determining the motor’s characteristics, such as speed, torque, and efficiency.

Our automated winding machines ensure precision, maintaining consistent turns and layering. Precision and uniformity in winding are crucial to minimize losses and maximize motor efficiency.
