Lamination Bonding And Stacking For Brushless Motor

BLDC motor lamination bonding and stacking involve a single stator rotor lamination stacked together to form a complete motor core.

electrical steel lamination stacking

Glue bonding uses the adhesive applied to the lamination sheets, which are then stacked to the desired height for assembly. Self-bonding laminations eliminate the need for additional adhesives, streamlining the manufacturing process while ensuring structural integrity.

The interlocking motor lamination process involves the interlocked points of each single lamination being pressed down into the one underneath it in the progressive die.

For more robust bonding, we employ laser welding and TIG welding technique ensuring a strong and durable bond between laminations. We also offer riveting and cleating processes for securing laminations, providing mechanical reinforcement in high-stress areas.

BLDC lamination stacks FAQs

Laminations are crucial in brushless motors because they provide a path for the magnetic flux generated by the stator windings. By laminating the core, eddy current losses are minimized, improving motor efficiency and reducing heat generation.

Silicon steel (also known as electrical steel) and iron are the most commonly used materials for BLDC motor laminations due to their magnetic properties and low electrical conductivity, which helps minimize eddy current losses.

We also offer amorphous alloy materials, nickel alloys, and cobalt alloys.

The stacking factor refers to the ratio of the actual cross-sectional area of the core to the total cross-sectional area available for the core. A higher stacking factor indicates better space utilization and can contribute to higher motor efficiency.

Precise alignment during lamination stacking is achieved through automated stacking machines or fixtures that hold the laminations in place during assembly. Additionally, precision cutting techniques and quality control measures ensure uniformity and alignment accuracy.

Selecting brushless motor laminations for multi-rotor drones, like those crafted from silicon steel, ensures optimal efficiency and performance. These laminations minimize energy loss from eddy currents, optimizing magnetic flux for smoother operation and longer flight times. Quality materials are essential for maximizing power output while minimizing heat generation and energy consumption.
