Let Sino's Lamination Stacks Empower Your Project!
To speed up your project, you can label Lamination Stacks with details such as tolerance, material, surface finish, whether or not oxidized insulation is required, quantity, and more.
Motor Core Lamination Stacks Manufacturer
At Sino, we specialize in manufacturing the motor lamination stack that forms the very heart of high-performing, reliable electric motors. Our manufacturing processes are geared towards producing motor lamination stack components with exceptional thinness, uniform insulation, and precise stacking, ensuring those eddy currents are minimized right from the design stage.
Sino's Material Advantage in Taming Hysteresis
Beyond Basic Iron: At Sino, we utilize specialized electrical steels, often referred to as silicon steel. Adding a small percentage of silicon (typically ranging from 1% to 4%, though sometimes higher for specific needs) to iron does a couple of wonderful things. Firstly, it significantly increases the material’s electrical resistivity, which gives an extra helping hand in suppressing eddy currents. Secondly, it alters the steel’s crystalline structure, making it easier for those tiny magnetic domains to flip back and forth. This reduced “magnetic friction” directly translates to lower hysteresis losses.
The Grain Game – Oriented vs. Non-Oriented
- Non-Oriented (NO) Electrical Steel: These steels have magnetic properties that are largely uniform in all directions within the plane of the lamination. They’re widely employed in rotating machines like motors and generators where the magnetic flux doesn’t always follow one neat path. Sino produces countless motor core lamination components from various grades of NO steel.
- Grain-Oriented (GO) Electrical Steel: This is the premium stuff. During its production, GO steel is processed to align the crystallographic grains in a specific direction. This gives it exceptionally good magnetic properties (like low hysteresis loss and high permeability) along that “easy” direction of magnetization. It’s the go-to for transformer cores, but also sees employment in certain high-efficiency motor designs where the flux path is highly predictable. Sino has the capability to process GO steels when the scenario demands peak performance along a defined axis.
Let’s look at a simplified comparison:
Table 1: Sino’s Perspective on Core Material Choices & Their Impact
Feature & Sino Focus | Standard Carbon Steel (Solid – Hypothetical for Motors) | Sino Non-Oriented Silicon Steel Laminations | Sino Grain-Oriented Silicon Steel Laminations (Thinner) |
Lamination Thickness (Sino Range) | N/A (Solid & Inefficient) | 0.35mm – 0.65mm (Common Sino Offerings) | 0.18mm – 0.35mm (Sino High-Performance Options) |
Eddy Current Losses (Relative) | Sky High | Low | Very Low |
Hysteresis Losses (Relative) | High | Low to Moderate | Ultra Low (in grain direction) |
Sino’s Contribution to Core Loss Reduction | (Baseline – Not Recommended) | Excellent | Superior (for specific flux paths) |
Typical Sino Motor Scenarios | — | Versatile: Industrial Motors, Appliances | High-Efficiency Motors, Specialized Applications |
(This table is illustrative. Sino offers a wide range of material grades and thicknesses tailored to specific customer requirements.)
The selection of the right grade of electrical steel, its careful handling to preserve magnetic properties (avoiding undue stress, for example), and precision stamping or laser cutting are all part of Sino’s commitment to delivering a superior motor core lamination.

The Sino Effect – Powering Up Performance, Extending Lifespans
Skyrocketing Efficiency
Less energy wasted as heat directly translates to more electrical energy being converted into useful mechanical work – the actual turning of the shaft. For any scenario where motors run for extended periods, from factory automation to your home air conditioning, the energy savings from a high-efficiency motor built with quality motor lamination stack components from Sino can be substantial over its lifetime.
Reduced Operating Temperatures
Lower core losses inherently mean less heat generation.This means the insulation on the copper windings lasts longer, as excessive heat is a primary cause of insulation breakdown and motor failure.It can reduce or even eliminate the need for bulky and expensive cooling systems (like fans or liquid cooling), making the overall motor design more compact and cost-effective.Motors can operate more reliably in hotter ambient environments without derating or premature failure.
Increased Power Density
Because a motor built with Sino's high-quality motor laminations wastes less energy as heat, engineers can often coax more power out of a given motor size. Alternatively, they can design a smaller, lighter motor to deliver the same power output.
Steadier Performance
Excessive heat can cause the magnetic properties of the core material to degrade over time, leading to a gradual decline in motor performance. By keeping things cooler, Sino’s motor laminations contribute to more stable and predictable motor operation throughout its service life.
Sino's Dedication to Your Unique Motor Needs
At Sino, we understand that “one size fits all” rarely works in the world of advanced motor design. That’s why we’ve built our capabilities around not just producing high-quality motor laminations, but also around providing tailored solutions.
Precision Manufacturing Toolkit
We employ a range of manufacturing techniques to create the perfect motor core lamination for your scenario:
1
Stamping
For high-volume production, our precision stamping presses create laminations with tight tolerances and excellent repeatability.
2
Laser Cutting
When you need prototypes, complex geometries, or smaller batches, our advanced laser cutting systems offer incredible flexibility and precision without the need for expensive tooling.
3
Annealing
This critical heat treatment process, performed in controlled atmosphere furnaces, relieves stresses induced during stamping or cutting and optimizes the magnetic properties of the electrical steel. Sino’s annealing cycles are meticulously controlled for each material grade.
4
Interlocking, Welding, or Bonding
We offer various methods to join the individual motor laminations into a robust and dimensionally stable motor lamination stack, including interlocking (creating small mechanical joins between laminations), laser welding along the outer diameter, or bonding with specialized adhesives. The choice depends on the motor’s operational demands and design.
Your Vision, Our Expertise
Do you have a specific slot design? A unique pole count? Are you targeting an unprecedented efficiency level? Bring it on. Our engineering team thrives on collaboration. We work closely with our clients to understand their specific performance targets, operating conditions, and assembly requirements. We can advise on material selection, lamination thickness, insulation types, and stacking methods to create a motor lamination stack that is perfectly optimized for your motor.
Quality at Every Step
From incoming raw material inspection to final dimensional checks on the finished motor lamination stack, quality is embedded in Sino’s DNA. We utilize advanced metrology equipment and rigorous process controls to ensure that every lamination and every stack meets or exceeds your specifications. This meticulous attention to detail is what ensures the consistent performance our customers have come to expect.
Sino in Action: Real-World Success
The Electric Vehicle
In an electric vehicle, every ounce of battery power is precious. High-efficiency motors, built with top-tier motor core lamination stacks, mean more miles per charge. Sino's laminations contribute to making EVs a more practical and appealing option for drivers everywhere by maximizing range.
Industrial Robotics
A factory floor packed with robotic arms working 24/7. If those motors overheat, production stops. Sino’s motor laminations help these critical components run cooler, ensuring higher uptime and productivity. A single line stoppage can cost thousands, so reliability here is paramount.
Power Tools & Appliances
You want a cordless drill to be powerful but also lightweight and comfortable to hold. Or consider a modern, sleek washing machine that needs to fit into a tight space but still have a powerful motor for spinning heavy loads. Improved power density, facilitated by excellent motor lamination stack design, makes this possible.
