1、The front cover, middle shell and back cover of brushless motor are mainly the overall structural parts, which play the role of building the overall structure of the motor. But the outer rotor brushless motor shell is also the magnetic pathway of the magnet, so the shell must be the composition of the material of magnetic conductivity. The casing of the inner rotor is only a structural part, so it is not limited in material. But the inner rotor motor is more than the outer rotor motor a rotor iron core, the role of this rotor iron core is also to play the role of magnetic pathway.
2, magnet: is mounted on the rotor, is an important part of the brushless motor, brushless motor performance parameters are mostly related to the magnet, including power, speed, torque, etc..
3, silicon steel sheet: is an important part of the slotted brushless motor, of course, the slotless brushless motor is no silicon steel sheet, but the vast majority of brushless motors are currently slotted. Its role in the whole system is mainly to reduce the magnetic resistance, participate in the magnetic circuit operation.
4, shaft: is the direct force part of the motor rotor, the hardness of the shaft must be able to meet the requirements of high-speed rotation of the rotor.
5, bearing: is the smooth operation of the motor to ensure that the bearing can be divided into sliding bearings and rolling bearings, and rolling bearings can be subdivided into deep groove ball bearings, needle bearings and angular contact bearings and other ten categories, and most of the brushless motor is currently using deep groove ball bearings.
