What are laminated magnets?

Laminated permanent magnets are specially designed magnetic components that are made by cutting a whole magnet into many smaller magnets, which are then glued together with a specific glue, and which are insulated from each other to minimize electromagnetic eddy currents. For example, rare earth magnets are glued to each other or to a steel plate, with the entire stack having the same polarity.

Characteristics of laminated magnets

1. Good surface magnetic consistency;

2. The unique production method increases the competitive advantages of production efficiency, manufacturing precision and cost control;

3. The magnet adopts integral plating surface protection technology, which has excellent resistance to high temperature, humidity and corrosion;

4. Insulating these small magnets from each other by means of insulating stitching;

5. The thickness of the insulating layer is within 0.04mm;

6. The bonding strength of the insulating layer at room temperature can reach more than 50Mpa;

7. Maximum working temperature up to 200°C;

8. The geometric tolerance of laminated magnets is within ±05mm;

9. They are available in samarium cobalt and neodymium iron boron materials;

10. Customized sizes and shapes are also acceptable.

Why choose laminated magnets?

Laminated magnets reduce eddy current losses in high efficiency motors. High efficiency requires the best materials, and Arnold L-Type laminated magnets have been proven to reduce eddy current losses in high-efficiency motors. Less eddy current loss means less heat and less waste.

Key Applications for Laminated Magnets：

The aerospace, automotive, motorsports and industrial markets are now turning to laminated rare-earth magnets in an effort to balance the trade-off between power and heat.

Question 1: What are the benefits of using laminated magnets?

A: Laminated magnets reduce eddy current losses, increase flux density, improve thermal stability and reduce magnet size.

Question 2: How are laminated magnets made?

A: Laminated magnets are made by stacking thin layers of magnetic material with insulating layers and then bonding them together using processes such as hot pressing or epoxy bonding.

Question 3: What are laminated magnets used for?

A: Laminated magnets are used in applications such as electric motors, generators, transformers and magnetic sensors.

Question 4: What types of magnetic materials are used to make laminated magnets?

A: Laminated magnets can be made from a variety of magnetic materials, including neodymium-iron-boron (NdFeB), samarium-cobalt (SmCo), and ferrite.

Question 5: What are the key design considerations for laminated magnets?

A: Design considerations for laminated magnets include the thickness and number of magnetic and insulating layers, as well as the bonding process used.

Q6: Are laminated magnets environmentally friendly?

A: Laminated magnets are generally considered to be more environmentally friendly than solid magnets because they require less magnetic material and produce less waste during the manufacturing process.
