在本实施例中,还进行了聚磁锥度设计,具体如下:In this embodiment, magnetic condensation taper design is also carried out, as follows:
在空气隙内,B0=μ0H0,由磁通连续性原理,磁路内部磁感应强度Bm值可由下式计算:In the air gap, B 0 =μ 0 H 0 , based on the principle of magnetic flux continuity, the value of the magnetic induction intensity B m inside the magnetic circuit can be calculated by the following formula:
B0=Bm·Sm/S0 B 0 =B m ·S m /S 0
式中:S0是修正后的磁极面积,磁极修正方法是在磁极的每边各加2l0,单位为mm2。公式中,若不考虑极头顶端饱和及漏磁情况,通过Sm/S0(聚磁锥度)比值设计就可获得想要的高B0,但是极头顶端最小面积处磁通量将是主体极柱的Sm/S0倍,才能实现需要的磁场。In the formula: S 0 is the corrected magnetic pole area. The magnetic pole correction method is to add 2l 0 to each side of the magnetic pole, and the unit is mm 2 . In the formula, if the saturation and magnetic leakage conditions at the pole tip are not considered, the desired high B 0 can be obtained through the S m /S 0 (magnetic concentration taper) ratio design. However, the magnetic flux at the minimum area of the pole tip will be the main pole. The S m /S of the column must be 0 times to achieve the required magnetic field.

In the design of structural parameters, the focus is on optimizing the magnetic concentrator taper, air gap area, pole area and other parts that affect linearity and magnetic field strength.
