Axial Permanent Magnets

Alnico magnets are composed of aluminum, nickel, and cobalt. They may also include small quantities of copper and iron. These permanent magnets are usually highly resistant to corrosion. Also, they have high mechanical strength. Alnico magnets are most often anisotropic. Alnico magnets are used for microphones, electric motors, and sensors.

Selection Criteria of Axial Permanent Magnets

• Capacities that commonly determine burden depths.

• Separation objective: Should you prioritize the recovery or removal of ferrous materials as your main separation goal?

• If you prioritize recovery, consider your purity target for the metal you are recovering.

• If you prioritize removal, consider the separation target of the ferrous component.

• What is the particle size of the ferrous and non-metallic metals you are handling.

Permanent Magnets Types

Ferrite Magnet

Ferrite magnets are a non-metallic magnetic material, also known as magnetic ceramics. They have a wide range of applications. Ferrite magnets do not have high magnetic properties. Typically, the magnetic energy product (one of the parameters to measure the performance of magnets) can only be slightly higher than 4MGOe.

Rubber Magnet

Rubber magnet is one of the series of ferrite magnetic materials. It is a flexible, elastic, and twistable magnet made by bonding ferrite magnetic powder and synthetic rubber and extruding, calendering, injection molding, and other processes. Generally, its magnetic energy product is 0.60～1.50 MGOe. Rubber magnets can be processed into strips, rolls, sheets, blocks, rings, and other various complex shapes.

SmCo Magnet

The main components of SmCo magnets are samarium and cobalt. Since the above two materials are expensive, SmCo magnets are one of the most expensive magnets available on the market today.

Neodymium Magnet

Due to their excellent magnetic properties and ease of processing, relatively low price, neodymium magnets, or NdFeB magnets are currently widely used and rapidly-developing magnet products.

AlNiCo Magnet

AlNiCo magnet is an alloy composed of metals aluminum, nickel, cobalt, iron, and other trace metal elements, and its magnetic energy product can reach 9MGOe. AlNiCo magnets are widely used in the field of sensors.

Advanced magnetic material technology

Precision manufacturing process

Features of Permanent Magnets

High-performance permanent magnetic materials: High-performance rare-earth permanent magnetic materials (such as NdFeB or NdFeB) or ferrite permanent magnetic materials are used to ensure the strength and stability of the magnetic field.

Precise structural design: Through precise mechanical design, it realizes the rotation and transformation of the magnetic field, and at the same time ensures the structural strength and stability of the product.

High-efficiency conversion: Efficiently convert magnetic energy into mechanical or electrical energy to improve energy utilization efficiency.

Customized service: Provide diversified customized service, adjusting the magnetic field strength, rotation speed and other parameters according to customer needs.

Application of Permanent Magnets

Hard drives, motors, vehicles, generators, TVs, phones, headphones, speakers, transducers, and sensors all require permanent magnets. A magnet's most common purpose is to attract other magnetic things, but it also serves a variety of tasks in electrical devices.

The majority of speakers use a permanent magnet that interacts with a wire coil (an electromagnet, really). The audio signal travels along the cable and causes the speaker to move. The speaker creates sound by moving air.

Magnetic hooks or closures are frequently found on cabinets or other furniture doors. Typically, they are manufactured using a cheap ceramic magnet sandwiched between two steel plates that attract and touch a steel “strike plate” on the door.

FAQ

Q: What is an axial magnet?

A: Axially Magnetized. Axially magnetized means the material is magnetized through the length of the magnet. In disc and block magnets, for example, this provides the largest surface area for holding.

Q: Is Axial the same as Radial?

A: A simple way to compare radial vs axial loads is to consider the direction of force. Specifically, if force is applied perpendicularly to a shaft, the load is radial. If the force is applied in the same direction as a shaft, the load is axial.

Q: What are the two types of permanent magnet motors?

A: Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor.

Q: Why are magnets polarized?

A: Magnetic polarization occurs when an external magnetic field is applied to a material with elementary magnets. Because the magnetic moments then add up, the external magnetic field H0 becomes around the magnetic field constant μ reinforced (corresponds to the magnetic permeability).

Q: What is the axial position of a magnet?

A: The line joining the North Pole and the South Pole of a bar magnet is called the axial line of the bar magnet.

Q: What is the axial magnetic effect?

A: The axial magnetic effect, i.e., the generation of an energy current parallel to an axial magnetic field coupling with opposite signs to the left- and right-handed fermions, is a nondissipative transport phenomenon intimately related to the gravitational contribution to the axial anomaly.

Q: What is the service life of rotating field permanent magnets?

A: The service life of rotating field permanent magnets depends on a variety of factors, such as the conditions of use, maintenance and so on. Under normal use and maintenance, the service life of a product is usually long. We provide detailed usage and maintenance guidelines to help customers extend the service life of their products.

Q: Can rotating field permanent magnets be customized?

A: Yes, we provide customized service for rotating magnetic field permanent magnets. Customers can adjust the magnetic field strength, rotation speed and other parameters according to their needs. Our professional team will design and manufacture according to your needs to ensure the products meet your requirements.

Q: In which fields are rotating magnetic field permanent magnets applied?

A: Rotating field permanent magnets are widely used in motors and generators, sensors and measuring devices, automation equipment and medical equipment.
