High Powerful Samarium Cobalt (Rare Earth) Bomatec Magnets, High Power Density Motor Laminated Magnet Arc-Type, Snake Line Laminated SmCo Magnet Arc, Eddy Current Loss Permanent Laminated Type Magnets, magnet segmentation technology
High Powerful Samarium Cobalt (Rare Earth) Bomatec Magnets N45H, N40SH, N38SH, N50, N48H – Laminated magnets are made by bonding several pieces of thin magnets together via special isolation glue which also be called magnet segmentation technology, and thus dramatically reduce the eddy flux loss of the magnets without changing the structure and performance of the motors. Actually, puzzles existing in the development of laminated magnets are the assembly process and consequently high costs. HSMAG has collected much experience via some axial flux motor projects. Snake Line Laminated Magnet Arc
1.The thickness of insulating layers is within 0.04mm.
2. In normal temperature, the bond strength of insulating layers can reach more than 50Mpa.
3. The maximum working temperature can reach 200 ℃.
4. The whole geometric tolerance is within 0.05mm.
5. These small magnets are insulated from each other.
In most cases, the eddy current loss of permanent magnets is much lower than iron loss and copper loss of the motor, but it will generate a large temperature rise in the high-speed motor and the high power density motor.
Ideally, stator magnetic field and rotor magnetic field of PMSM are rotating synchronously, or relatively static, thus permanent magnets without eddy current loss in such case. In fact, there are a series of space and time harmonics are existing in the air gap magnetic field, and these harmonic components are stemming from cogging effect, non-sinusoidal distribution of magnetomotive force and phase current. The harmonic magnetic field will link with rotor magnetic field and hence generated eddy current and caused relevant eddy current loss. It should be also noted that the harmonic magnetic field and eddy current loss will rise with increasing motor speed. High Power Density Motor Laminated Magnet Arc-Type
