Stator And Rotor Laminations Production Process For Brushless DC Motor
BLDC Motor Lamination Prototype
We specialize in three different motor lamination prototype fabricating methods: single slot punching, laser cutting, and wire EDM cutting. Single-groove punching ensures efficiency in creating uniform slots.
The laser cutting process employs a focused laser beam to precisely cut through the material, facilitating intricate designs and maintaining tight tolerances.
On the other hand, wire cutting utilizes a thin, electrically charged wire to make accurate cuts, ideal for intricate patterns and complex geometries.
With a commitment to excellence, our brushless DC motor lamination prototypes boast a remarkable lead time of 7-15 work days, allowing for swift development and testing.
Lamination Stamping For BLDC Motor
With 10 years of experience in the industry, we employ cutting-edge techniques such as progressive stamping, compound stamping, and rotary notching to manufacture the best brushless DC motor rotors and stator core laminations.
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 BLDC motor manufacturing.
Compound stamping for brushless 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 brushless DC motor stator or rotor laminations 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.
In the production of BLDC motor lamination stacks, our bonding processes involve securely joining individual laminations to form the iron core. We offer two cutting-edge methods: glue dot bonding and self-bonding technology.
Glue dot bonding involves applying adhesive dots strategically, creating a secure bond between laminations. This method offers flexibility and efficiency in stack assembly.
On the other hand, Backlack self-bonding technology utilizes the electrical steel materials coated with bonding varnish to form a cohesive stack without additional adhesives. This process enhances durability and simplifies assembly.
