Capability For Stamping Rotor Iron Core Laminations

Stamping rotor laminated is a precise and essential process in the manufacturing of electric motors. We provide rotary notching, compound, and progressive stamping process.

This technique involves cutting, shaping, and punching lamination steel sheets to create the laminated cores of the rotor, which are crucial for the motor’s performance and efficiency.

Punching ensures uniformity and accuracy in the size and shape of each laminated, allowing for tight tolerances and minimal energy loss due to eddy currents.

Our punching laminated needs stacking and bonding to form complete motor lamination stacks. The rotor is a vital component of motors. Our fabrication and assembly service includes laser welding, TIG+MIG welding, cleating, riveting, self-bonding, gluing, etc.

Laser Cutting Rotor Core laminations

Laser cut laminations are a highly precise manufacturing method that employs a focused laser beam to cut, engrave, or shape electrical steel lamination materials with exceptional accuracy.

This process excels at creating complex laminated shapes, making it ideal for applications that require specific geometries to optimize motor performance. It is a non-contact process, which reduces the material risk of contamination or damaged magnetic properties enhancing the efficiency of electric motors and generators.

Laser Cutting Company is renowned throughout the motor and generator industry for manufacturing high-quality parts per customer specifications with the highest quality control standards.

Our engineers and designers can iterate designs rapidly, accelerating the development process. It is suitable for both prototyping and small-scale production.

Rotor Laminations FAQs

Motor laminated forms the core of an electric motor’s stator and rotor. They consist of thin metal sheets that are welded, or bonded together. By making them from individual pieces of metal rather than solid pieces.

Reduced Eddy Current Losses
Rotor laminated are typically made from thin, insulated sheets of metal. The insulation between the laminate helps minimize current losses, which occur when magnetic fields induce circulating currents in the metal.

Improved Magnetic Properties
Laminates are precisely punched or laser-cut to shape, ensuring consistent dimensions and alignment of the magnetic cores. This results in improved magnetic properties and a more efficient conversion of electrical energy to mechanical energy.

Lower Noise and Vibration
The laminated’s tight stacking and uniformity reduce electromagnetic noise, contributing to quieter and smoother operation.

Enhanced Heat Dissipation
The thin and stacked nature of laminates allows for efficient heat dissipation. Heat generated during operation can be more effectively conducted away from the core, preventing overheating and prolonging the life of the motor or generator.

Our motor laminations are used in a wide range of applications including industrial, power generation, manufacturing, aerospace, and transportation. These rotor laminations serve an essential purpose by powering heavy machinery with superior efficiency.

We know what rotor and stator laminate are, so let’s dive into the key differences between stator and rotor of electric motors.


The stator core is located in the stationary part of the motor core, known as the stator. The stator surrounds the rotor and remains fixed in place.

Rotors are situated within the rotating part of the motor, which is the rotor. The rotor spins within the stator.


Stator laminations play a primary role in generating a rotating magnetic field when electrical current flows through the stator windings. This magnetic field interacts with the rotor to induce motion.

Rotor laminations serve to provide a magnetic path for the magnetic field generated by the stator. As the magnetic field rotates, it exerts a force on the rotor laminations, causing the rotor to turn and produce mechanical output.


The increased thickness helps stator laminations withstand higher mechanical loads as they remain stationary.

The rotor’s reduced thickness allows for efficient magnetic flux generation and response to the changing magnetic field from the stator.


Stator motor laminations are typically made from the same material as rotor laminations, which are often silicon steel, cobalt, and nickel alloys. This material exhibits excellent magnetic properties and low electrical conductivity.

Rotor motor laminations are also typically crafted from high-grade silicon steel. The choice of silicon steel helps reduce core losses and enhances motor efficiency.


Stators usually have a more complex and larger shape, as they need to surround the rotor and create a rotating magnetic field. The stator laminations are designed to accommodate stator windings and provide a path for the magnetic field.

Rotors tend to have simpler shapes, often circular or rectangular.
