How Does Magnetization Of Magnet Help Attain Desired Energy?

Magnetization, also called magnetic polarization, refers to evaluating the density of induced or permanent dipole moment in a magnetic material. It helps in categorizing different magnetic materials based on their magnetic properties. Various applications need magnets with different properties. And to attain these properties, it is vital to magnetize sustainable magnets using the right techniques.

This article will discuss the significance of magnetization and how it can help create the best motors.

Risk of Using Unsaturated Magnets

Ideally, bonded magnets require high energy for magnetizing the products compared to sintered or ferrite magnets. Using less than the required energy can result in the development of unsaturated bonded magnets. Such magnets create a low airgap flux, resulting in poor performance of the motor.

Here are some major demerits of unsaturated magnets:

• Decreased motor efficiency

• Increased risk of magnet's demagnetization.

• Higher no-load speed.

• Lower stall torque

• Lower power output and more.

Hence, it is crucial to magnetize the bonded magnets properly to avoid such issues. And that's where the magnetizing process comes into play.

Understanding A Magnetizing System

Typically, a magnetizing system includes a fixture and a magnetizer. The fixture is generally custom-made based on the application, while the magnetizer doesn't necessarily need any customization. The fixture's design can be in the form of multi-pole arrangements or simple solenoids.

Magnetization can be carried out during any stage in the magnet manufacturing process. Experts conduct the magnetization process using professional FEA (Finite Element Analysis) software to produce simulated results. These results make it easy to evaluate the performance of the motor accurately, which, in turn, helps lower the motor development time.

Understanding the Motor Design Phase

As discussed above, magnetizing is analyzed by utilizing FEA software. The primary aim of this software is to accurately simulate the field and saturate a rotor magnet effectively. A fixture design begins with electromagnetic simulations. During the thermal design process, cooling and thermal requirements are calculated.

In the end, a stress analysis is carried out to analyze the forces influencing the rotor. The service provider can export the data and provide it to its customers so that they can make the necessary changes in mechanical design.

Automation of Magnetization Process

A magnetizing system can be easily incorporated into your existing automation system. This will help in faster magnetization, rotor positioning, measurement, etc. An automated magnetizing process is an excellent way to attain repeatable and fast magnetization. While large rotors can be challenging to handle, you can enjoy a faster rotor measurement with an automatic magnetizing process.

A Way to Ensure Maximum Mechanical Strength

Magnets exposed to mechanical stress regularly can face volume loss, which can cause deterioration in the magnet's magnetic field. However, by magnetizing the magnets, you can restore the magnetic field. Besides, this will also help increase the magnetic strength.

Magnetic Storage

In applications such as hard drives and magnetic tapes, magnetization is utilized for data storage. These storage devices use tiny magnetic regions on their surfaces that can be magnetized to represent binary information (0s and 1s). By applying a magnetic field, the magnetization of these regions can be altered, allowing for the recording and retrieval of digital data. This enables the storage and retrieval of information, which is a crucial aspect of modern computing and data processing systems.

Closing Thoughts

Overall, magnetization plays a significant role in energy-related applications by enabling the conversion, transfer, and storage of energy in various forms. By manipulating the magnetization of magnets, it is possible to attain the desired energy outcomes in these systems.

One of the best ways to eliminate the risk of unsaturated bonded magnets and create powerful, sustainable magnets is by accurately magnetizing the magnets. So, contact a trusted magnetizing solution provider today to know more about it and get the best magnets for your product.
