China Neodymium And Ferrite Magnets Manufacturer & Supplier 
In many types of motors (such as brushless motors, DC motors, fan motors, vacuum cleaner motors, and robot motors), magnets are one of the core components. Some netizens may ask, "What is the magnet inside the motor actually called?" In reality, depending on the material, structure, shape, and other factors, the magnet inside the motor can be referred to by various names. Below are some commonly call names.
The First Commonly Used Term - Permanent Magnet
This is a relatively universal designation. Permanent magnets in motors generate electromagnetic force by providing a stable magnetic field, thereby enabling rotation. Common materials include: sintered neodymium iron boron, bonded neodymium iron boron, injection-molded neodymium iron boron, sintered ferrite, injection-molded ferrite, and samarium cobalt.
Second Way of Calling It - Magnetic Tile
This designation is based on the magnet's shape, resembling a tile while possessing magnetic properties. Magnetic tiles are also known as curved arc magnets, curved magnetic blocks, fan-shaped magnets, segmented magnets, etc., and are typically mounted on motor stators or rotors. Currently, the market primarily features sintered neodymium arc magnets and ferrite arc magnets.
The accompanying illustration shows the curved magnets commonly used in electric motors.
The third naming convention - magnetic ring
Also known as multi-pole magnetic rings, these are integrally molded and primarily magnetized with multiple poles. They are particularly suitable for brushless motors and encoder motors. Based on material, they can be categorized into ferrite multi-pole magnetic ring and neodymium iron boron multi-pole magnetic ring.
The fourth naming convention - rotor magnet/stator magnet
According to the different installation positions of magnets, if installed in the rotating part of the motor, it is called rotor magnet, and if installed in the fixed part, it is called stator magnet, among which rotor magnet is more common.

The fifth naming convention - Magnetic Steel
Unrestricted shape and material, such as motor magnet steel, high-performance magnet steel, usually referring to sintered neodymium iron boron.
The sixth naming convention - adhesive magnetic ring/injection molded magnetic ring
If the motor uses bonded neodymium iron boron or injection molded ferrite, it is often referred to as bonded magnetic ring, injection molded magnetic ring, or injection molded rotor magnet. Among them, injection molded magnetic rings are not fragile, easy to process complex structural shapes, and have more magnetic poles.
