Description

Technical Field

[0001] The invention relates to the technical field of enhanced sinusoidal waveform magnetic rings, in particular to an enhanced sinusoidal waveform magnetic ring. Background Art

[0002] Hall induction magnetic rings are mostly homogeneous ferrite magnetic rings. This type of ferrite magnetic ring has stable magnetic properties and distinct magnetic poles, providing a stable magnetic pole signal for the Hall induction element, and is therefore widely used in speed measurement. According to the different requirements of brushless motors, there are two types of axial multi-pole magnetic rings and radial multi-pole magnetic rings. The surface magnetism of the magnetic ring is generally around 1000GS, so the magnetic properties are neither too strong nor too weak, just enough to provide a signal to the Hall induction element, and will not affect the normal operation of the motor's own magnetic ring. However, due to different industries, the professional terms for the products are also different, including Hall induction magnetic rings, multi-pole induction magnetic rings, Hall induction magnetic poles, radial induction magnetic rings, radial multi-pole magnetic rings, etc. However, after understanding the use of the product, it can mostly be determined that it is a Hall induction magnetic ring. The homogeneous radial multi-pole Hall induction magnetic ring has a low price and stable magnetic properties and is widely used in brushless motors, stepper reduction motors and other products.
