Abstract

The invention relates to a rotor structure of an outer rotor type brushless motor, and belongs to the technical field of motors. The rotor structure comprises a shell, permanent magnetic steel and an output shaft; the shell comprises a fixing ring and a connecting cylinder, the permanent magnetic steel is symmetrically fixed on the connecting cylinder about the axis of the connecting cylinder, the fixing ring is fixed at one end of the connecting cylinder, a shaft sleeve coaxially arranged on the fixing ring is slidably connected into the fixing ring, a fixing part used for detachably connecting the shaft sleeve into the fixing ring is arranged between the shaft sleeve and the fixing ring, and the output shaft is coaxially arranged in the shaft sleeve and slidably connected into the shaft sleeve; and a connecting assembly used for detachably connecting the output shaft into the shaft sleeve is arranged between the output shaft and the shaft sleeve. The structure has the effect that the shell and the output shaft are independently detached, so that resource waste is reduced.

Description

technical field [0001] The present application relates to the technical field of motors, in particular to the rotor structure of an outer rotor type brushless motor. Background technique [0002] At present, brushless motor is a typical electromechanical integration product. With the increasingly mature and perfect technology, it has developed rapidly. In recent years, it has become a driving force for rapid development in the field of models. It has been widely used in many fields such as automobiles; the outer rotor motor has the characteristics of saving space, compact design and high specific power. [0003] The existing outer rotor type brushless motor includes a stator and a rotor. The stator includes multiple sets of winding coils. The rotor includes a casing, permanent magnets and output shafts. The casing wraps the winding coils inside itself, and the permanent magnets are fixed on the On the circumferential inner wall of the shell, the output shaft is fixed on the...
