Lamination stacks have become an essential component in the manufacturing of high-performance electric motors, especially in the electric vehicle and emerging electric aircraft industries. This blog will discuss what lamination stacks are and why they are crucial for effective motor function. We will also explore several reasons you should choose lamination stacks, especially those offered by Carpenter Electrification.
What Are Lamination Stacks?
Lamination stacks are thin layers of soft magnetic alloys stamped into a designed shape, i.e. a lamination, and stacked together to create a magnetic core for an electric motor. These lamination materials are either silicon steel or iron cobalt and are coated with an insulating material to prevent eddy currents and losses. This core is used to direct and control the flow of magnetic fields, which creates the motion required for the motor to operate.
Why Are Lamination Stacks Used in Motors?
Lamination stacks are used in motors to reduce losses, increase efficiency, and improve performance. Thinner laminations have lower losses and help to improve motor responses at high frequencies. Stacks from iron-cobalt laminations such as Hiperco® 50 can provide the highest power and torque density.
Reasons You Should Use Lamination Stacks
The highest-performing lamination stacks result in a more efficient motor, reducing operating costs, increasing performance, and improving durability. Several reasons to consider lamination stacks are as follows:
-
Reduced energy loss: Lamination stacks minimize energy loss by reducing the eddy currents within the motor.
-
Increased efficiency: By improving the losses in the motor lamination stacks increase overall efficiency and performance.
-
Improved performance: Lamination stacks using iron cobalt materials enhance performance by allowing for higher power and greater torque generation.
-
High frequency motors: As one tries to go towards higher speed, the operating motor frequencies increase. Thinner laminations have lower eddy currents and can run at high frequencies with lower losses than thicker laminations.
-
Customizable: Lamination stacks can be customized to meet the specific needs of each application, making them ideal for a wide range of applications.
-
Reduced size: By using Hiperco lamination stacks, the weight and size of the motor can be reduced, making it more compact and easier to install in tight spaces. This makes them ideal for applications where space is limited.
