Brushless motor to magnet performance shape and pole number requirements

The magnet in the brushless motor is mounted on the rotor and is one of the important parts of the brushless motor.

Magnet performance reguirements for brushless motors:The brushless motor mainly uses high performance NdFeB strong.   magnels, Because the power of the motor is closely related to the performance of the magnet,itcan bebasically understood that the volume and grade of the neodymium magnet determine the maximum power of the motor

Magnet shape reguirements for brushless motors:

The shape of the brushless motor magnet mainly includes rectangle, arc, sector,trapezoid, ring magnet, and a bread shaped magnet

The fewer the poles, the higher the rotational speed

Adyantages of Sauare-shaped magnet: simple processing, relatively cheap price, a good choice for the pursuit of cost motor. Advantages of cuved magnets: The arc shape ensures that the air gap behween the magnet and the silicon steel sheetis always the same, and it seems that the power andefficiency are better than the square maqnet.

Advantages of bread-shaped magnets: There are professionals who think that this magnet is better than a curved magnet

Advantages of the ring magnet.  Easy to install, superior performance, High-end generals use rings.

The number of poles of the brushless motor requires: the fewer the pole pairs, the higher the speed

For permanent magnet motor magnet, our company has a strong strength and a larger price advantage, looking forward to your consultation.
