Brushless dc motor rotor
- Jan 26, 2019 -


The rotor of the brushless dc motor is composed of permanent magnets with a certain number of poles embedded on the surface of the core or embedded in the core.Permanent magnets are mostly made of rare earth permanent magnetic materials with high coercivity such as ndfeb and high permeability magnetic induction density.The permanent magnetic steel of the rotor is similar to the permanent magnetic steel used in the brushless motor in that it builds up enough magnetic field in the air gap of the motor. The difference is that the permanent magnetic steel of the brushless dc motor is mounted on the rotor, while the permanent magnetic steel of the brushless motor is mounted on the stator.The rotor structure of brushless dc motor mostly
