Description

Technical Field

[0002] At present, watches, especially pointer-type quartz watches, are easily affected by magnetic fields and stop watches. According to the characteristics of the magnetic field, the external magnetic field will strengthen or offset the original magnetic field. Since the pointer-type quartz watch is realized by the stepper motor, the stepper motor rotor is made of magnetic steel and the stator is made of soft magnetic material. Its magnetic field is generated by the inductor coil and has a certain direction, which always reverses with the reverse direction of the coil current. The superposition effect is most obvious when the direction of the magnetic field generated by the coil is consistent with the direction of the external magnetic field. Therefore, considering the magnetization direction of the external magnetic field, the influence on the pointer-type quartz watch is greater.

Therefore, it is necessary to design a watch anti-magnetic performance detection device. Utility Model Content
