Embodiment Construction
[0013] In conjunction with accompanying drawing, provide embodiment of the present invention as follows:
[0014] Such as figure 1 The one shown adopts a set of two-phase demagnetization pole groups, which is composed of demagnetization pole A and demagnetization pole B. The coil 1 installed on the iron core 2 is connected to the two-phase power supply. The two demagnetization poles are on the same plane, and the included angle is 90 degrees. .
[0015] Such as figure 2 As shown, two groups of demagnetization pole groups are used, and each group of demagnetization poles is composed of three demagnetization poles. The demagnetization coils are arranged in a "Y"-shaped array, and can also be arranged in a "△"-shaped array, forming A1 and B1 on the S surface. , C1 three demagnetization poles, there are A2, B2, C2 three demagnetization poles on the X surface, the three demagnetization poles form a plane rotating magnetic field, and the coils on the three magnetic poles are conn...
