Get more power from your machines with Sino CRNGO Lamination Stacks. Our CRNGO lamination stacks are like the strong heart of your electric motors and generators. We make special Cold Rolled Non-Grain Oriented (CRNGO) steel layers. These layers provide real, measurable improvements in how well your machine works, how much power it has, and how long it lasts. These CRNGO laminations give you great performance without a high price tag. This makes them a smart choice that is a very good value for your money. Think of us as your helpful partner, here to solve your toughest engineering problems.
Our CRNGO lamination stacks are made to prevent energy loss. This means your equipment runs cooler. It also saves you money on electricity bills. Our CRNGO laminations are the perfect choice for any machine with a spinning magnetic field, such as AC or DC motors. We use the best non-oriented electrical steel, which is also called silicon steel. This lets us make a product you can always trust. Our carefully made parts are designed to lower energy waste. They also increase your power and give you performance you can count on. This gives your motors and transformers a real edge over the competition around the world.
With Sino CRNGO lamination stacks, you get a powerful set of advantages that make your products better. Our making process focuses on the things that are most important to engineers. This brings real, helpful benefits to the product you are building.
To understand why our CRNGO lamination stacks are the best choice, let’s look at the details. The performance of a CRNGO lamination stack starts with the steel we use. We offer many different types of CRNGO steel. Each type is designed for certain performance levels and budgets.
Product Feature | Sino’s Simple Explanation | Why It Matters for Your Machine |
Material Grade | We offer many grades of steel, like M270-50A5 and M400-50A5. You can pick between semi-processed and fully processed electrical steel. | Choosing the right grade gives you the best mix of power and price. High-quality steel is great for very efficient motors, like the ones in electric cars (EVs). |
Lamination Thickness | Our steel sheets are very thin. You can choose a lamination thickness of 0.35mm or 0.5mm. | Thinner steel sheets are better at stopping a type of energy waste called eddy current loss. This is very important for machines that spin very fast, like power tools. |
Insulation Coating | Each steel sheet has a special insulation coating. We offer different types, like a C-3 coating (Organic) or a C-5 coating (Inorganic). This is part of the C-coating classification (ASTM A976). | This special coating acts as a barrier. It stops electricity from jumping between the steel layers of the CRNGO lamination stack. This makes your machine safer and more efficient. We can also use a C-6 coating, varnish, or other coatings. |
Magnetic Power | Our CRNGO lamination stacks have a high magnetic power capacity. This means they can hold a lot of magnetic power before they get full. | More magnetic power means your motor is stronger. This is great for big factory machines and the powerful compressors in things like refrigerators. It’s a key part of making strong electromagnets. |
Electrical Resistance | The steel we use resists the flow of electricity well. | This feature helps stop wasteful eddy currents from forming inside the steel. It is one more way our CRNGO laminations help you save energy and get better performance. |
Stacking Factor | We pack our CRNGO laminations tightly together. The stacking factor measures how much steel is in the stack. A higher number is better. | A high stacking factor means we pack more steel into a small space. This lets you get more power from a smaller stack. It helps you build machines that are smaller, lighter, and more powerful. |
Table 1: Sino CRNGO Grade Overview (Example)
Grade Designation | Nominal Thickness (mm) | Max Core Loss (W/kg) @ 1.5T, 50Hz | Key Characteristics & Primary Applications |
Sino-EC530 | 0.50 | ≤ 5.30 | Go-To Grade: A great mix of performance and price for everyday motors and appliances. |
Sino-EC470 | 0.50 | ≤ 4.70 | High Efficiency: Less energy waste, for IE2/IE3 motors and power transformers. |
Sino-EC350 | 0.35 | ≤ 3.50 | For High Speeds: Thin layers to greatly reduce energy loss in high-speed motors and EV motors. |
Sino-EC270 | 0.35 | ≤ 2.70 | Top Performance: Very little energy waste for the toughest jobs, like in IE4/IE5 motors. |
Sino-HS400 | 0.50 | ≤ 4.00 | Extra Strong: Built to be stronger for parts that spin very fast and face a lot of force. |
Making the perfect stator or rotor core takes a lot of care. We control every step of the making process, from start to finish. We turn the best raw steel into a finished CRNGO lamination stack that has been tested for great performance.
We start with a large roll of CRNGO steel. We use a special machine to cut it into smaller strips. We are very careful to make sure the edges are clean and smooth, with no rough spots.
We use high-speed machines to punch and stamp out the shapes for the CRNGO laminations. For very complex designs, we use laser cutting. We can make any shape you need, from a UI lamination to a complex round core.
The stamping process creates stress in the steel, which can weaken its magnetic power. After stamping, we use a very careful heating process called Stress Relief Annealing. This step is very important because it:
We carefully put the CRNGO laminations together to build the final stack. We offer different high-quality insulation coatings and ways to hold the stack together. This makes sure your core is strong and works well magnetically.
Table 2: Sino Lamination Bonding Method Comparison
Bonding Method | Key Advantage | Best Suited Applications |
Laser/TIG Welding | Very strong, good price. | Best for jobs that need the strongest and stiffest parts. |
Interlocking | No extra parts needed, low cost. | Good for motors where saving money is important. |
Adhesive Bonding | Best magnetic performance, makes less noise. | Perfect for high-performance motors, like in EVs and robotics. |
Sino CRNGO lamination stacks are used in thousands of different products all over the world. We design special solutions for many different industries.
