EV Motor Core FAQs

The core of electric vehicles is the three-electric technology, motor, battery, and electronic control technology. Motor stator and rotor lamination stacks are core components of electric vehicle motors. They consist of laminated sheets or strips of electrical steel and play a crucial role in converting electrical energy into mechanical motion in EVs.


High-quality motor lamination stacks are designed to minimize core losses, which include hysteresis and eddy current losses. Reduced core losses mean that more of the electrical energy supplied to the motor is converted into mechanical energy, improving overall motor efficiency. This efficiency is critical for maximizing the range of electric vehicles and minimizing energy consumption.


Quality lamination stacks are engineered to optimize magnetic properties, ensuring that the motor can generate the necessary magnetic fields for propulsion efficiently. This results in improved torque, acceleration, and overall vehicle performance.

Heat Management

Lower core losses in high-quality laminations lead to reduced heat generation within the motor. Excessive heat can degrade insulation materials and affect motor performance and longevity. Quality lamination stacks help manage heat more effectively, contributing to motor reliability and longevity.

Noise and Vibration Reduction

Well-designed lamination stacks can help minimize electromagnetic noise and vibration in the motor, contributing to a quieter and smoother ride for electric vehicle occupants. This is particularly important for enhancing passenger comfort.

At present, there are the following types of drive motors for electric vehicles: DC motors, AC induction motors, permanent magnet brushless DC motors, permanent magnet synchronous motors, and switched reluctance motors. Our motor lamination stacks are suitable for a wide range of electric vehicles, including electric cars, electric bikes, electric buses, and other EV applications that require efficient and reliable electric motors.

There are several types of thin gauge electrical steel available, each with its unique properties and applications. Understanding these varieties is essential in making the choice of the right materials for your EV application.

Electrical Steel (Silicon Steel)

Electrical steel, often referred to as silicon steel, is the most common material for stator and rotor laminations in EV motors. It is specifically designed for electric motor applications due to its excellent magnetic properties. Electrical steel is typically alloyed with silicon to enhance its electrical resistivity and reduce eddy current losses, making it ideal for use in laminations.

Grain-Oriented Electrical Steel (GOES)

In some high-efficiency electric motors, particularly those used in premium or high-performance EVs, grain-oriented electrical steel (GOES) may be used. GOES has a crystalline grain structure oriented in the direction of magnetic flux, further reducing core losses and improving motor efficiency.

Non-Grain-Oriented Electrical Steel (NGOES)

Non-grain-oriented electrical steel is used in motors where the magnetic field direction varies, such as in some induction motors. While it may have slightly higher core losses compared to GOES, it is well-suited for certain EV applications.
