Stator Laminations FAQS

Stator laminations are used to reduce eddy current losses, which occur when a magnetic field induces circulating currents in the conducting material. By using laminations, these losses are significantly reduced, leading to improved motor efficiency.

Electrical steel, also known as silicon steel, is the most common material for stator laminations. It has high magnetic permeability and low electrical conductivity, making it ideal for minimizing eddy current losses. Other soft magnetic materials, such as nickel and cobalt alloys, may also be used for specific applications.

In EVs higher up the performance scale and in heavy-duty commercial vehicles, where the application requires higher torque and power density, high-induction and low-loss cobalt-iron alloys come to the fore.

Yes, various types of stator laminations are available to suit different applications and requirements. The choice of material, lamination design, and manufacturing process may vary based on factors such as motor speed, power rating, and environmental conditions.

The prototyping process for the stator laminate core typically takes 7-15 days, considering the need for precision in design, material selection, and manufacturing methods to ensure optimal performance and efficiency.

Stator laminates find widespread use in various industries, including automotive for electric vehicles, power tools, power generation, renewable energy, industrial machinery, and household appliances.
