The magnetic field of the motor is generated by the magnets in motors. The greater the working flux produced by the magnets, the total number of armature conductors required by the rotor can be reduced correspondingly, which is very beneficial to the motor. On the one hand, the armature resistance of the motor can be correspondingly reduced, so that the copper wire loss of the motor can be correspondingly reduced, and the efficiency can be correspondingly improved. On the other hand, the total number of conductors required by the motor rotor is reduced accordingly, and the slot slowness rate of the motor is reduced accordingly, so that the embedding of the motor rotor becomes easy. If the motor flux is improved on the premise of the same magnet, the volume of magnet will increase, the volume of magnet is determined by the thickness and length of the magnet, the length of the magnet is determined by the length of the rotor, now mainly to determine the thickness of the magnet. The thickness of magnet is thin, the magnet is easy to demagnetization, the process is not good. The thickness of magnet is thick, the magnetic properties of the motor can not be greatly improved, but more consumption of magnetic
materials, the cost is greatly increased, so it is necessary to determine the thickness of magnets. Tel. of Hangzhou Xinfeng magnetic materials Co., Ltd. : 0571-86817293.
