In the rare earth permanent magnet motor, some of the magnetic steel is rounded with tiles, some are directly used squares, and the two are different. What are the advantages and disadvantages of the tile-shaped magnetic steel and the rectangular magnetic steel?
The following is a comprehensive sharing of Caricie Magnet Xiaofu finishing network, I hope to help you.
The following picture shows the square magnet steel for the motor (rectangular magnetic steel)
1.Tile type magnetic steel is used for surface mount, and rectangular magnetic steel is used for built-in. A permanent magnet brushless DC motor requires a square wave waveform, and the built-in magnetic steel air gap magnetic density waveform is closer to a square wave.
2. The air gap of the tile type magnetic steel is uniform, the rectangular magnetic tile is attached, and the air gap is not uniform.
3. Even if it is a rectangular magnetic steel, the geometry of different magnetic poles is different, especially the built-in type is more complicated.
PS: At present, the main use of square magnet steel is the scooter motor, the torsion car motor, and of course some other motors are possible, which are related to the customer's specific design.
