Lamination Stacks for Linear Motor Stator Manufacturer

At Sino, we know that the most important part of a powerful linear motor is its set of linear motor stator laminations. We design our advanced linear motor stator laminations to give you unmatched power, very little jerky movement, and excellent energy use. This directly leads to better accuracy, higher speed, and a longer life for your machines.

We do more than just sell parts. We provide the basic magnetic structure that helps you create new things. This is true for many different fields, from making computer chips to building fast trains. We are dedicated to careful manufacturing, using the best materials, and understanding how you will use our products. This makes sure that every set of linear motor stator laminations we make gives you a real edge over your competition.

Expertise Across All Linear Motor Types

Choosing the right type of linear motor is a very important first step. This choice decides the basic design needs for the linear motor stator laminations. Sino is an expert in making the best linear motor stator laminations for the three main types of linear motors. We handle the special problems of each type by choosing the right materials and using specific making processes.

Permanent Magnet Synchronous Linear Motors (PMSLM)

PMSLMs give you the most power and use energy very well. Because of this, they are used in the toughest jobs. Our linear motor stator laminations for PMSLMs are made to focus the magnetic field and reduce energy waste. They work for both powerful iron-core motors (used in factory machines, packaging, and large movers) and very smooth ironless (slotless) motors (used for making computer chips and precise measuring).

Linear Induction Motors (LIM)

LIMs are popular because they are strong, reliable, and have a simple second part. This makes them perfect for systems that travel a long way, like airport trams, roller coasters, and factory conveyor belts. When we design linear motor stator laminations for LIMs, we focus on cutting down energy waste. We also improve the magnetic path to lessen problems at the ends of the motor. This helps them work reliably, even when there is a wider gap between parts.

Linear Reluctance Motors (LRM)

LRMs don’t use magnets. This makes them strong and reliable in very hot places. They are also a lower-cost option for moving things. Our linear motor stator laminations for LRMs are designed to get the most out of their special magnetic properties (saliency). At the same time, we control magnetic overload and reduce uneven force by shaping the teeth perfectly. This makes them great for tough, dependable movers.

We can make a sample, or prototype, for you very quickly. When you are ready for more, we can make thousands of parts for you.

Made for Tough Working Conditions

Sino’s products are built to work well in many kinds of difficult situations.

  • Temperature Extremes: We choose special coatings (like C-5 inorganic) and insulation for our linear motor stator laminations. These can handle very high heat (like Class F and H systems). This keeps the insulation safe and reduces unwanted electrical currents, even when it gets very hot.
  • Duty Cycle: Our linear motor stator laminations are designed to handle quick changes from hot to cold. They also prevent magnetic overload when there is a sudden burst of power. This protects the magnets, even when the motor is working 3 to 6 times harder than normal for a short time.
  • Ingress Protection (IP): Our linear motor stator laminations can be treated with special sealants, coatings, and protective shells. This helps them meet high protection standards like IP65, IP67, and even IP69K. This means they are safe to use in wet or dirty places where they might be washed down.
  • Vibration and Shock: For parts that move very fast (at 5 to 10 g’s of acceleration), our bonded linear motor stator laminations (using Backlack) are a great choice. They are stronger and better at absorbing shakes than parts that are just locked together. This makes them quieter and more durable.
  • Chemical Exposure: We choose coatings and treatments for our linear motor stator laminations that can resist damage from chemicals. This includes things like coolants, oils, and cleaning fluids.
  • Cleanroom/Vacuum: For making computer chip e area clean. It also makes them suitable for super-clean rooms (ISO Class 1–3) and vacuum spaces.

The Heart of Your Motor: Our High-Quality Materials

The material we use for your linear motor stator laminations is the most important choice. It decides how strong and fast your motor can be. A good material lets the magnetic field flow easily with very little wasted energy. This waste is also called core loss or iron loss. Sino offers many kinds of materials to fit your needs.

We carefully pick our metals so they have the best magnetic properties. This means they can create strong magnetic fields with little effort. They also don’t hold on to magnetic energy after the power is turned off.

Our Material Choices:

  • Silicon Steel Sheets: This is a very popular choice. It is strong and works very well. We offer both non-grain-oriented (NGO) steel and grain-oriented (GO) steel. We have many grades like M19, M27, and M36. We also use thin-gauge electrical steel for high-speed jobs. These cold-rolled linear motor stator laminations are very reliable.
  • Cobalt and Nickel Alloys: For the most powerful motors, we use special metals. Cobalt alloys, similar to those known as Hiperco 50, are great for motors that need huge power in a small space. Nickel alloys, like HyMu 80, are perfect for sensitive tools. These materials have a very high saturation flux density.
  • Advanced Modern Materials: Sino is always looking for what is next. We use amorphous metals and nanocrystalline materials for motors that spin very, very fast. We can also use soft magnetic composites (SMCs). We work with material science leaders, including those who pioneered amorphous metals, to source the best options. We get our steel from top suppliers in North America and Asia, ensuring it meets standards set by major steel corporations.

Built with Perfect Precision: Our Making Process

Sino uses the latest making processes to produce high-quality linear motor stator laminations. We find the right balance between being exact, affordable, and able to make large amounts. Our process ensures every piece has very tight tolerances. This means each part is almost exactly the same size and shape. A good stacking factor means we fit many layers in a small space.

Manufacturing Capabilities:

  • Stamping (Progressive Punching): This is the best method for making a lot of parts cheaply. Our fast machines create parts that are very precise (within ±10–20 μm) and have very small rough edges (less than 5–10 μm).
  • Laser Cutting: This method is perfect for making samples, small batches, or tricky shapes. With laser cutting, there are no extra costs for tools. This lets us make changes quickly. The parts are accurate to within ±20–50 μm.
  • Wire EDM (Electrical Discharge Machining): This uses a spark to cut the metal. It is very, very exact.

Preparing the Layers: Each metal sheet gets a special insulation coating. This stops electricity from jumping between the layers. We can also use injection molding insulation. This is key for reducing unwanted electrical currents (eddy currents). We also perform an annealing process, which is a heat treatment that makes the metal’s magnetic powers even better. This is part of our standard surface treatment.

Bonding and Assembly Methods

  • Backlack/Bonding: This is the method we like best for top-performing linear motor stator laminations. It makes them very strong, reduces shaking, and ensures all layers stick together evenly.
  • Interlocking: A fast, low-cost assembly method for making a large number of parts.
  • Lamination Welding/Laser Perimeter Welding: This method makes the stack of linear motor stator laminations strong. We are very careful in our design to not create paths that would let unwanted electrical currents flow.

Finally, we perform encapsulation to protect the stator winding and core. This makes the whole unit, or forcer, strong and safe.

Powering the Future: Where Our Laminations Are Used

Sino’s linear motor stator laminations are trusted in many areas. They are used in machines that need to react quickly and do the exact same motion over and over. Our parts help build everything from tiny robots to giant trains. Because our parts create a direct drive motor, there is no need for gears, which means no backlash.
