Wind Power Employs Asynchronous Generator Lamination Cores

In the realm of renewable energy, wind power stands out as a key player in the transition towards a sustainable future. Among the various components of wind turbines, the asynchronous generator lamination core emerges as a crucial element, offering a plethora of advantages that contribute to the efficiency and reliability of wind energy generation. Let’s delve deeper into the benefits of asynchronous generators and their significance in the context of wind power.

What Is Asynchronous Motors?

Asynchronous motors, also known as asynchronous generators or induction generators, are utilized to convert the kinetic energy of the wind into electrical energy. These motors operate on the same principles as conventional asynchronous motors but are configured to function as generators in wind turbine systems.

In the realm of wind power generation, asynchronous motors, often referred to as asynchronous generators or induction generators, serve as vital components within wind turbines. These motors, operate on the same fundamental principles as traditional asynchronous motors, converting the kinetic energy of the wind into usable electrical power.

The stator of an asynchronous motor in a wind turbine comprises a stationary core with a series of wire windings. When connected to an alternating current (AC) power supply, the stator windings produce a rotating magnetic field.

Within the asynchronous motor, the rotor is a rotating component that interacts with the magnetic field generated by the stator. As the wind turbine’s blades turn, they drive the rotor’s rotation. The rotor can be of the squirrel-cage or wound-rotor type, but in wind turbines, the squirrel-cage rotor is commonly used due to its simplicity and reliability.

Advantages of Asynchronous Generators

Simplicity And Stability

Asynchronous generators are prized for their straightforward design and exceptional stability. Unlike synchronous generators, they operate without the need for excitation control, simplifying their construction and enhancing their reliability.


One of the standout features of asynchronous generators is their ability to adapt to a wide range of wind speeds. Whether operating at low or high speeds, these generators can effectively harness wind energy and maintain stable power output.

Efficiency and Cost-effectiveness

Asynchronous generators boast high efficiency and low manufacturing and maintenance costs, making them a cost-effective solution for wind power generation. Their uncomplicated design reduces production expenses, while their minimal maintenance requirements contribute to long-term savings.

Lamnow is a professional manufacturer of motor, generator, and transformer laminations. Our high-quality rotor and stator core packs are widely used in various applications. In wind power areas, we employ advanced techniques and processes to ensure lamination superior performance and reliability. 

We offer segmented stamping, compound stamping, and single-slot notching processes to meet customer needs.  The segmented stator laminates stamping is suitable for large and mass-production generator laminations. Compound stamping allows for the simultaneous formation of multiple features on a single lamination steel. It is ideal for medium and large lamination cores. Single-slot notching technology is cost-effective for large laminations and prototypes.

In lamination prototyping, we offer laser cutting and wire EDM technology to create custom-shaped slots and channels within silicon steel laminations.

After stamping and cutting, Lamnow carefully stacks the individual laminations to form the core of the asynchronous generator. Various techniques may be employed for lamination stacking, including glue bonding, self-bonding, riveting, cleating, and welding, depending on the specific requirements of the design.

Once the core is assembled, we proceed with stator winding, where insulated copper wires are carefully wound around the slots in the laminations. Our automation winding process is conducted with precision to ensure uniform distribution of coils and optimal electrical performance.

Whether it is prototyping or mass production, we can provide a complete solution. Contact us today to discuss your project needs.
