Progressive Stamping

progressive stamping for motor lamination

In progressive stamping for motor laminations, a continuous strip of metal, usually made of silicon steel due to its magnetic properties, is fed through a series of dies and presses.

The dies are strategically designed to perform multiple operations sequentially with each stamping press stroke. These operations include cutting, bending, and shaping the metal strip to form the desired motor lamination shape.

The reduced material waste and increased production rates make progressive stamping a preferred choice for industries seeking to meet high-volume production quantities while maintaining cost efficiency.

Unlike traditional methods, the compound stamping process involves the simultaneous operation of tools on a single press stroke, enabling the creation of intricate and complex shapes.

This technique is particularly advantageous for motor laminations with intricate designs or shapes, enhancing efficiency and reducing production time.

The resulting motor laminations exhibit excellent flatness and concentricity, meeting the stringent requirements of medium and large electric motor applications.

Compound Stamping

Rotary Notching

rotary notching for motor lamination

Rotary notching is a cost-effective solution for large electric motor laminations and low-to-medium volume production.

This process eliminates the high tooling costs and extended lead times associated with traditional stamping methods.

Our CNC Rotary Notching press utilizes a servo-driven indexer capable of reaching speeds up to 1,200 strokes per minute. This high-speed capability, combined with precise position indexing tolerance, can produce fixed rotor laminates with a maximum outer diameter of 1250mm.

Hybrid Stamping combines various stamping techniques to achieve a balance of speed, precision, and flexibility. It is suitable for low-to-medium volume production.

This process meet motor lamination for stringent industry tolerances for concentricity, flatness, and hole locations.

The hallmark of efficiency, our tooling is designed for rapid manufacturing, providing a quick turnaround in weeks, not months, to meet the demands of dynamic production schedules.

Helical Stamping

helical stamping for motor lamination

The procedure involves punching elongated bands of sheet steel to create strip laminations with tooth and core back portions. These strip laminations are then spirally wound and integrated, forming a stator core with enhanced structural integrity.

This helical stamping approach not only streamlines production but also optimizes the stator’s magnetic properties, showcasing a novel technique that combines precision punching and spiral winding for superior performance in electric motors.

Materials Used In Motor Laminations Stamping

Silicon Steel

This is the most widely used motor lamination material. Its high magnetic permeability and low core loss make it ideal. Silicon steel is often coated to minimize eddy current losses during operation. We provide 0.1mm – 1mm thickness lamination steel.

Cobalt Alloys

These cobalt alloys offer excellent wear, corrosion, and heat resistance and are known for their high saturation magnetization, making them suitable for high-performance motors where space and weight constraints are critical.

Nickel Alloys

We use nickel alloys to stamp parts. Because they’re highly permeable at low to moderate inductions, and they also do not possess high core losses, nickel-based alloys effective in shielding applications and certain types of transformers.

Thin-Gauge Electrical Steel

Motor laminations are produced by thin-gauge electrical steel employed for applications where minimizing core losses is crucial. Thinner gauges help reduce eddy current losses, improving motors’ overall efficiency.
