laminated magnets
Electric motors and generators with high efficiency demands are used in heavy-duty applications, such as industry, automotive, motorsport, and space exploration. In these motors, it is desirable to reduce heat loss to the lowest possible level. Permanent magnets can play a major part in losses generated by the presence of eddy currents.
laminated magnets
Eddy currents can be efficiently reduced in permanent magnets by lamination, sometimes also referred to as segmentation. This technology splits the permanent magnet into smaller, electrically isolated parts. Various magnet shapes can be laminated to produce various widths of the partial segments. Common magnetic materials for lamination are NdFeB and SmCo.
characteristics of laminated magnets
- reduction of eddy currents and heat loss
- lamination width from 1 mm
- applicable for NdFeB and SmCo
lamination design
The appropriate choice of magnet lamination is a key task of optimal structural design. The lamination method affects the eddy current reduction effect and the resulting magnet price. Contact us for a consultation on your project.
