A simple and fast method for distinguishing magnesium zinc and nickel zinc ferrite ferromagnetic rings There are also many answers online about how to distinguish between magnesium zinc and nickel zinc ferrite magnetic rings. Most of them talk about manganese zinc ferrite and nickel zinc ferrite, rather than magnesium zinc. Magnesium and zinc may have less contact and may not be very clear. Below, the editor will share a simple and quick method to distinguish magnesium zinc and nickel zinc ferrite, hoping to be helpful to you!Adobepdff: The simplest way is to estimate the density. Magnesium zinc density is much smaller than nickel zinc density, or it can measure high-frequency inductance. At high frequencies, nickel zinc has obvious advantages.T2Q: Using detection element frequency, the difference between the two is the content of ironWonshen: Nickel and zinc are non-conductive, while magnesium and zinc are conductive. There is a significant difference in the breakdown voltage of the magnetic core when these two materials are used as withstand voltage wires.: 25

Application and magnetic properties comparison of barium ferrite and strontium ferrite Everyone is familiar with ferrite, which can be divided into isotropy and anisotropy. According to different molding processes, anisotropic ferrite can be divided into dry pressing and wet pressing. According to the main components, ferrite permanent magnets are mainly divided into two types: barium ferrite (BaO · 6Fe2O3) and strontium ferrite (SrO · 6Fe2O3). Below, we will introduce the directionality, characteristics, and magnetic properties of barium ferrite and strontium ferrite.In recent years, due to environmental and health reasons, barium based ferrites have been discontinued, and currently strontium based ferrites are mainly used in the market.The main uses of barium ferrite and strontium ferrite;The main products of permanent magnet ferrite are anisotropic series, which are particularly suitable for use as permanent magnets for small generators and motors. They can replace aluminum nickel cobalt permanent magnets and are used for making permanent magnet ignition motors, perma: 25

What are the performance characteristics of soft magnetic ferrite? The maximum magnetization can be achieved with the smallest external magnetic field, which has low coercivity and high permeability, making it easy to magnetize and demagnetize. Generally, soft magnetic materials have narrow hysteresis loops with coercivity below 100A/m.Special Introduction to the Segmentation Problem of Permanent Magnets (Magnetic Tiles) in Electric Motors1. What happens when the magnetic tile segments of a permanent magnet motor are different in length?This depends on the specific situation, depending on whether the indexing is different on the circumference or the thickness is different in the axial direction? If the indexing on the circumference is not the same, it will definitely not be possible, as it will result in different numbers of poles and magnetic flux per pole of the motor. This is not allowed or necessary. If the axial size of the magnetic tile is inconsistent, it is acceptable, as long as it is fully arranged in the length of the iron core.2. What is t: 25

Anisotropic ferrite radial multipole magnetic ring The production of Y30BH anisotropic ferrite radial multipole magnetic rings has always been a technical challenge in the magnet industry. Ferrite radial bipolar magnetic rings are easy to produce, and most magnet factories can produce and process them. However, the production process of ferrite radial multipole magnetic rings is limited by their strict technical advantages, especially for ferrite radial magnetic rings with large product specifications, which require strong technical support.The figure below shows an 8-pole magnetic ring filled outward with sintered ferrite, with a surface magnetism of over 1900, which can basically reach a peak of ferrite magnetic strength.After the anisotropic ferrite magnetic ring undergoes mold pressing production, a matching magnetization fixture is required to achieve radial multipole magnetization. Usually, the mold cost of a conventional ferrite radial multipole magnetic ring and the magnetization fixture cost vary from 18000 to 25000 yuan, and: 25

Notes on the Processing of Oil Sprayed Paint Magnetic Rings and Introduction to the Function of Spraying 1. When choosing paint, it is important to ensure that it is environmentally friendly. If it is not environmentally friendly, even if it is cheap, no one dares to use it. Paint belongs to a class of solid chemical products, and many people know that chemicals have an odor, and long-term contact can also be harmful to human health. Even when spraying magnetic rings, it is necessary to wear a gas mask to operate.2. When spraying paint, it is necessary to process the magnetic rings according to the color chosen by the customer, including black, white, yellow, red, blue, green and other colors available on the market. However, the quantity must be completed according to the customer's purchase order.3. Operational issues. Nowadays, many large spraying factories use automated spraying, which is very convenient and faster than manual spraying. They can also spray more uniform magnetic rings, unlike manual spraying, which is not as complex and has multiple processes, and the spraying is s: 25

The multipole magnetic ring of the motor is also divided into internal and external charging Many novice friends are not familiar with magnets, so they are not very clear about one of their magnetization methods. They mistakenly believe that magnets only have axial and radial magnetization, but in fact, there are many other magnetization methods for magnets. Today, we are talking about two types of magnetization methods for motor magnetic rings: internal and external.What does it mean? Simply put, internal charging, that is, internal charging, external charging, that is, external charging. So, if the magnet is charged internally, the strongest part of the magnetic field is on the inner R surface of the magnet, and vice versa, on the outer R surface.The magnetic ring of an external rotor motor is generally internally charged, such as commonly used internally charged 14 poles, internally charged 10 poles, internally charged 8 poles, and so on.Magnet radial internal charging and radial external charging come from this way, so it is best to be clear when inquiring with the magnet: 25
