10 poles neodymium Ring Magnet 45.9x41.4x13mm Physical picture

Brushless motor ring magnet refers to the magnet used in the rotor of brushless motor, which can be different designed and selected according to the construction and performance requirements of the motor.

Usually, there are several or dozens of strong and good magnetic permanent magnet magnets on the rotor of a brushless motor. These magnets will generate a magnetic field when the motor is running and interact with the coil in the stator to realize the rotation of the rotor.

Ring magnet is a common brushless motor magnet shape, which can effectively reduce the rotor inertia of the motor and enhance the response and dynamic characteristics of the motor. At the same time, the ring magnet can better realize the magnetic field distribution control and magnetic circuit design, so as to improve the efficiency and performance of the motor.

The types and specifications of ring magnets are also very diverse, which can be selected and applied according to the specific motor construction and working requirements. It should be noted that in the operation of the motor, the ring magnet will be affected by greater thermal stress and vibration, so it is necessary to pay attention to the selection of materials, processing technology and installation details in the design and production process.
