Description

Technical Field

[0001] The invention belongs to the technical field of magnetic field stability detection, and in particular relates to a device for detecting magnetic field stability after rotor magnetization. Background Art

[0002] The stability of the magnetic field is affected by many factors, including the type of magnet, design quality, ferromagnetic materials near the magnet, ambient temperature, and the stability of the magnet power supply. For example, the presence of ferromagnetic materials near the magnet may interfere with the magnetic field, causing changes in the magnetic field uniformity and field strength. Changes in ambient temperature may also affect the stability of the magnetic field, especially for permanent magnets and conductive magnets. In order to check the stability of the magnetic field, a magnetic field stability test is required. The magnetic field stability test is an indicator of the degree of drift of the magnetic field strength. When the magnetic field is detected after the rotor is magnetized after production, a magnetic field detection device needs to be applied.

The device overcomes the shortcomings of existing conventional magnetic field detection devices, and has the advantages of low power consumption, high sensitivity, high measurement accuracy, and high stability. At the same time, due to the use of a flexible substrate, it can be widely used in occasions such as the human body that require a flexible magnetic field detection device.
