Permanent Magnet

Permanent magnet materials, also known as "hard magnetic materials", refer to materials that can maintain constant magnetism once magnetized. In practice, the permanent magnet material works in the second quadrant of the hysteresis loop after deep magnetic saturation and magnetization. Commonly used permanent magnet materials are divided into rare earth permanent magnet, ferrite permanent magnet, metal permanent magnet, composite permanent magnet, etc. The magnets we mention generally refer to permanent magnet.

Soft Magnet

Magnetic materials with low coercivity (Hc≤1KA/m) and high permeability are called soft magnet. Soft magnetic materials are easy to magnetize and demagnetize, are widely used in electrical equipment and electronic equipment. It is mainly used for the conversion and transmission of magnetic and electromagnetic energy. The most widely used soft magnetic materials are FeSi alloy (silicon steel lamination), FeNi, FeCo and various soft ferrite.

Magnetic Assembly

Magnetic devices (assembly) refers to the assembly of magnets and other components together to achieve some specific functions including magnetic coupling, Halbach Array etc. We can provide magnetic simulation and also the precision fixture designing service for customer in the R&D stage. That’s why we are good at making the assembly with high-precision and complex magnetic and geometric requirements.


Motor can be divided into DC motor, asynchronous motor, synchronous motor according to the structure and working principle.

1) DC motor can be divided into brush DC motor and brushless DC motor.

2) Synchronous motor can be divided into permanent magnet synchronous motor, reluctance synchronous motor and hysteresis synchronous motor.

3) Asynchronous motor can be divided into: induction motor and AC commutator motor.

Kede mainly produces all kinds of brush motor rotor&rotor, EPS motor, Coreless motor and other customized motors. Furthermore we have a motor production line in Vietnam for better serving global customers.
