Neodymium Arc Segment Shape Lamination Magnet For Motor

Introduction of Laminated Magnet

High efficiency demands the best materials, and the Arnold L Type laminated magnets are proven to reduce eddy current losses in high-efficiency motors. Less eddy current loss means less heat and less waste.  In the aerospace, automotive, motorsport, and industrial markets are turning to laminated rare earth magnets, and are working to balance the tradeoff between power and heat.  Arnold minimizes the tradeoff by offering best-in-class materials with:

1. The thinnest available insulating layers, <20 um

2. Performance at temperatures up to 200˚C

3. Magnet layers from .5 mm and up in custom shapes and sizes in neodymium iron boron or samarium cobalt

MODELING WITH L TYPE MAGNETS

Calculation of eddy current losses with and without lamination are shown below. Our engineers can help to select an appropriate material and lamination thickness to perform optimally in your application, given your temperature and frequency requirements.

Application of laminated magnets:

Laminated magnets are often used in electric motors, generators, transformers, and other electromagnetic devices where controlling energy losses is essential.

WHAT SIZE LAMINATE DO YOU NEED?

Validated by an independant, outside laboratory, 1mm L Type RECOMA 33E separated by 18 micron polymer lamination, the thinnest available, offers both optimal magnetic performance and lowest resistance for high ef ciency motor applications.

ACHIEVE OPTIMUM PERFORMANCE

The optimal lamination for your application is a balance of the need for the greatest electrical resistance at the operating frequency and the best magnetic performance in the physical envelope of your application. Matching the right L Type insulation and magnet layer thickness to your application makes all the difference.

Essential Manufacturing Process of Laminated Magnets

NdFeB blanks are sliced into equal-thickness single pieces and then laminated with insulation glue. The fully laminated blank is then cut, sliced, and ground to the desired geometry and size, creating a complete laminated NdFeB magnet. The bonding adhesive typically achieves a maximum insulation rate of 95%. However, due to the adhesive, electroplating is not possible, as the magnet body is no longer electrically conductive. As an alternative, common coating solutions include epoxy-painting (usually black) or phosphorization.

FAQ

Q. Why is the price of sample higher than that of batch?

A: For samples we don't have any profit. We only charge the cost of materials and labor. As a manufacturer, the more quantity produced, the lower the unit cost.

Q. Do you support exchange and return service?If I buy a magnet and I can't use it.

A: We do not support return or exchange service. As you know, the magnet is a custom product, which is completely customized according to your requirements. This product cannot be resold to others.
