Helical Stamping Electrical Steel Laminations Manufacturing Capabilities
The helical stamping process for an electric lamination core involves several steps to create the desired shape and properties in the metal.
The process starts with the selection of high-quality electrical steel (often referred to as silicon steel) that has the appropriate magnetic properties for the application.
In the first step of the helical stamping stator core lamination process, a stacked plurality of long bands of sheet steel is punched to create strip laminations. These strips have distinct tooth portions and core back portions.
Unlike conventional square-sheet punching methods, helical stamping significantly minimizes iron waste. It is estimated to only require 30 to 40% of the material typically needed. This reduction in material waste is a significant advantage of the helical stamping process.
The punched strip laminations are then spirally wound and integrated, forming a unique helical pattern. This process is integral to achieving the “Slinky” configuration, which is characterized by its helical shape.
By intermeshing the protrusions and recesses of tooth portions, the helical stamping technique enhances efficiency.
Throughout the process, quality control measures are implemented to ensure the iron cores meet the required specifications for dimensions, tolerances, and magnetic properties.
Benefits of Slinky Stamping Electric Motor Laminations
Slinky stamping electric motor laminations offer numerous benefits, primarily due to their unique helical shape and the innovative manufacturing process used to create them. These benefits include:
Reduced Material Waste
The helical stamping process significantly minimizes iron waste, estimated to be only 30 to 40% of the material typically required. This reduction in material waste is cost-effective.
Improved Efficiency
By intermeshing the protrusions and recesses of tooth portions, slinky stamping enhances the efficiency of electric motors. This can lead to better performance, reduced energy consumption, and longer lifespan of the motor.
Enhanced Magnetic Properties
The helical pattern achieved through stamping can improve the magnetic properties of the motor cores. This can result in motors that operate more quietly and at lower temperatures.
Materials Used In Helical Punching Stator
The stator helical punching materials typically include silicon steel, which is a type of electrical steel specifically designed for use in magnetic devices such as motors and transformers. Its high silicon content helps reduce eddy current losses, making it ideal for efficient motor operation.

Laminations Helical Punching FAQS
Slinky stator core laminations differ from traditional laminations primarily in their helical shape, achieved through a unique spiral-winding process. Unlike conventional square-sheet punching methods, the helical stamping process for slinky laminations minimizes waste, making it more efficient and environmentally friendly.
Slinky stator core laminations are versatile and suitable for various applications, including but not limited to electric vehicles (EVs), alternators, and hub motor cores for EVs. Their helical design enhances motor efficiency, making them ideal for any application where high-performance electric motors are required.
The expected lifespan of motors using slinky stator core laminations can vary depending on factors such as usage, maintenance, and operating conditions. However, due to their high efficiency and reduced waste, motors with slinky laminations can potentially have a longer lifespan compared to those using traditional laminations.
