Circuit board fixed structure and motor that constructs including this fixed knot

The utility model discloses a circuit board fixed structure and motor that constructs including this fixed knot relates to the motor component field, and fixed knot constructs including bearing frameand sleeve, the bearing frame is connected with motor stator, and the sleeve assembles on the bearing frame, and the circuit board assembles on the sleeve. The bearing frame divide into upper end, thefirst axle body, the second axle body and third axis body, and the first axle body passes through rotation -proof structure with the sleeve to be connected, and motor stator passes the third axis body through the recess to interference fit is connected with the second axle body. The sleeve passes through the positioning column structure or the back -off structure of outside setting and is connected with the circuit board. This fixed knot structure has substituted the structure of wire frame among the prior art, and simple structure constructs the second axle body of axis bearing and is connected with motor stator thro
