Motor Lamination
High-Efficiency Motor Laminations for Electric Motor Performance
Modern electric motors must run faster and use less energy. Therefore, motor lamination quality becomes very important.
Because energy loss often starts inside the magnetic core, good laminations help motors work better. As a result, efficiency increases and heat drops.
Our motor laminations are designed for OEM customers in Europe and North America. Moreover, they support both prototype and mass production projects.
What Is Motor Lamination?

laminated motor core
Motor lamination is a thin steel sheet used inside motor stators and rotors.
In the past, solid steel cores were common. However, solid metal created strong current loss. Therefore, laminated sheets are now used instead.
Each sheet has an insulation layer. Because of this layer, electric current cannot flow easily between sheets. As a result, energy loss becomes much lower.
In simple terms, laminations help magnetic flow while stopping wasted energy.
Why Motor Laminations Matter
First, laminations guide magnetic flux.
Next, they reduce heat.
Finally, they keep the motor stable during operation.
Because these effects work together, overall motor efficiency improves.
Moreover, better laminations help reduce vibration. At the same time, motor noise becomes lower.
For this reason, motor makers focus strongly on lamination quality.
Key Benefits of Our Motor Laminations

Our Motor Laminations
1. Low Core Loss Design
We use high-grade electrical steel. Therefore, magnetic loss stays low.
Because thinner sheets limit circulating currents, heat generation drops. As a result, motors run cooler.
In addition, cooler motors last longer. Consequently, maintenance cost decreases.
This advantage is especially useful for:
-
Electric vehicle motors
-
Industrial drives
-
High-speed systems
2. High Precision Production
Accuracy affects performance. Therefore, tight control is required.
We control:
-
Sheet thickness
-
Slot size
-
Flatness
-
Burr height
Meanwhile, automated inspection checks every batch.
As a result, magnetic balance improves. Furthermore, torque output becomes smoother.
3. Stable Magnetic Performance
Motor output depends on magnetic stability. Therefore, lamination shape must be optimized.
We adjust:
-
Tooth width
-
Slot opening
-
Back iron size
Because geometry affects flux flow, even small changes matter.
Thus, efficiency improves while loss decreases.
4. Strong Mechanical Stability
Motors often run at high speed. However, weak cores may deform.
For this reason, our laminations use strong interlock structures.
In addition, stacking pressure stays uniform. As a result, the core remains stable over time.
Especially in EV motors, this stability is critical.
Motor Lamination Types

Lamination Types
Because motor designs vary, different lamination types are required.
Stator Laminations
Stator laminations hold motor windings.
Therefore, slot accuracy is very important.
Better slot design allows more copper fill. As a result, torque increases.
Rotor Laminations
Rotor laminations rotate at high speed.
Thus, balance accuracy must remain high. Consequently, vibration stays low.
Segmented Laminations
Segmented designs simplify winding work.
Because segments are easier to handle, automation improves.
As a result:
-
Production speed increases
-
Cost decreases
-
Quality stays stable
