The ring magnet in the ceiling fan motor is one of the important components of the motor, its function is to provide a static magnetic field, so that the rotor of the motor can rotate under the magnetic field.
If the ring magnet of the ceiling fan motor is 10 poles, there are 10 pole pairs on the magnet. On the magnet, the two adjacent magnetic poles have opposite north and south polarity and are 180 degrees apart. Such a number of polar pairs is also known as the "polar logarithm", is a key parameter in motor design, the increase of the polar logarithm will reduce the speed of the motor, and the torque will increase.

In short, the ring magnet of ceiling fan motor is one of the most important parts in the motor, which provides the rotating static magnetic field and determines the main performance parameters of the motor. In the design and manufacture of ceiling fan motor, it is necessary to determine the specific number of poles and magnet materials according to the need to meet the needs of different applications.
