Why did you come across Hellomag while looking for a magnet company?
Recently, as I had the opportunity to use industrial magnets, I started comparing several companies. At first, I was just trying to compare prices, but I found out that the performance and application areas of each type of magnet are quite different.
Then I found Hellomag . When I looked at the
homepage, the first thing that caught my eye was that was a company that not only sold magnets, but also handled Nd Sintered, Nd Bonded, Nd Injection, SmCo, and Ferrite magnets and motors.
In particular, the characteristics and magnetic data for each product were disclosed in relatively detailed detail, making it easy to determine which product was suitable for which purpose. What kind of product is
Ferrite Magnet?
Ferrite Magnet is one of the most commonly seen permanent magnets. The black magnet visible when disassembling the
speaker is called a Ferrite Magnet.
The features of Ferrite Magnet introduced by Hellomag are summarized as follows.
- Ceramic permanent magnet using iron oxide (Fe₂O₃) as the main material
- Material that does not use rare earth elements
- Highly price competitive product with low cost
- Structure that does not require separate plating
- Maximum operating temperature approximately 250~300℃
- Widely used in motors, speakers, sensors, etc.
In addition, the website provides a table of magnetic characteristics for various grades from FB5B to FB13B, making it convenient to select the required performance.
It was announced that custom grades tailored to customer requirements could also be manufactured. What is the difference between
Ferrite Injection Magnet? We also looked at the
Ferrite Injection Magnet.
This product is a composite magnet produced by mixing ferrite powder and thermoplastic resin such as PA6, PA12, and PPS and then injection molding.
The biggest difference compared to regular Ferrite Magnet is the manufacturing method. Based on the
website, the main features are as follows.
- Manufactured by injection molding method
- High dimensional precision
- Insert can be injected at the same time as the shaft
- Suitable for small motors and sensors
- Operating temperature approx. 100~150℃
- BHmax 1.0~2.5MGOe
product grades also varied depending on the resin used, such as Nylon6, Nylon12, and PPS. Why is the
product data disclosed in detail?
When looking at the websites of various companies, many of them only had product photos.
On the other hand, Hellomag has
- Magnetic Properties
- Grade
- Br
- Hcj
- Hcb
- BHmax Magnetic data such as
was also provided.
It seemed helpful for technical or purchasing personnel to be able to compare required performance in advance.
A PDF download is also provided so you can check all grade information at once. Is this a company that only sells
magnets?
What was surprising while looking around was that they also run a motor business.
In addition to magnets, Hellomag also introduces the following motor areas:
- BLDC motor
- PMSM
- Step motor
- Servo motor
Application areas include
- Electric vehicle (EV)
- Industrial Robot
- Smart Factory
- Automation Equipment
- We were providing guidance on home appliances ,
- ,
,
, etc.
It was introduced that since it handles both magnets and motors, it also proposes designs tailored to customer applications.
How is Hellomag’s business structured? I also checked the
company introduction page.
Hellomag is introduced as a company that provides technical solutions focusing on magnets and motors.
product lineup is as follows:

- Ferrite Magnet
- Ferrite Injection Magnet
From raw materials
- Sintering and injection
- Magnetization
- The process from
- quality control (QA)
- supply to
was introduced and the vision of growing into a global general trading company was also presented.
What did you feel while looking into the actual consultation?
When I looked at the website to find out about products, the most impressive thing was that the data was organized relatively systematically.
The difference between Ferrite Magnet and Ferrite Injection Magnet could be compared at a glance, and magnetic data by grade could also be checked, making it easy to review the product you needed.
They also introduce not only magnets but also motors, giving me the impression that this is a company that considers not only parts supply but also application areas.
If you are looking for a company related to industrial magnets or motors, I thought this was a company worth checking out for product information.
