The main properties of permanent magnet materials
Author：
The magnetic induction intensity value of the permanent magnet material when the external magnetic field is zero after the material is magnetized to saturation. This index data is directly related to the magnetic density of the air gap in the motor. The higher the magnetic induction intensity value, the higher the air gap magnetic density of the motor may be, the torque constant, back potential coefficient and other main indicators of the motor will reach the best value, the electrical load and magnetic load value relationship of the motor may be the most reasonable, and the efficiency can reach the best.
