Wholesale Discount Rare Earth Permanent Magnet - Lamination Neodymium magnet can reduce the eddy current loss – Xinfeng Detail:

PRODUCT INTRODUCTION

Laminated rare earth magnets can reduce eddy current losses in high-efficiency motors. Smaller eddy current losses mean lower heat and higher efficiency.

In permanent magnet synchronous motors, the eddy current losses in the rotor are ignored because the rotor and stator are rotating synchronously. In fact, stator slot effects, non-sinusoidal distribution of winding magnetic forces and harmonic magnetic potentials generated by harmonic currents in the coil winding also cause eddy current losses in the rotor, rotor yoke and metal permanent magnets binding the permanent magnet sheath

Since the maximum operating temperature of sintered NdFeB magnets is 220 ° C (N35AH), the higher the operating temperature, the lower the magnetism of the NdFeB magnets, the lower the conversion and power of the motor. This is called heat loss! These eddy current losses can lead to elevated temperatures, leading to local demagnetization of permanent magnets, which is particularly severe in some high speed or high frequency permanent magnet synchronous motor.

Heat loss is mainly caused by electromagnetic eddy current during motor operation. Therefore, multiple stacking methods (which require insulation between each magnet) to reduce this heat loss.

TECHNICAL REQUIREMENTS

1.The thinnest insulation, < 20 microns;

2.Performance at temperatures up to 220˚C;

3.Magnet layers from 0.5 mm and above are custom shaped and sized neodymium magnets.

SCOPE OF APPLICATION

High-speed permanent magnet motors, aerospace, automotive, motorsport and industrial markets are turning to laminated rare earth magnets and are working to balance the tradeoff between power and heat.

Advantages: it can reduce the energy loss caused by electromagnetic eddy current.
