Motor

A motor comprising:

• a stator comprising:
• a pillow comprising a plate, a shaft tube extended from a side of the plate and a cylinder extending axially from an opposite side of the plate relative to the shaft tube, wherein the plate has an inner side neighboring to the shaft tube, and the inner side of the plate has a first insertion hole for a first electrical connector to penetrate therethrough;
• a winding assembly circumferentially disposed on the shaft tube and comprising a conductive element extended out therefrom to connect to the first electrical connector;
• and
• a cover covering a side of the pillow opposite to the shaft tube;
• a rotor circumferentially disposed at the outside of the winding assembly and comprising a shaft, wherein the rotor is sleeved on the shaft tube and rotates along a central axis;
• a first circuit board disposed at the opposite side of the plate and electrically connected to the first electrical connector;
• a second circuit board electrically connected to the first circuit board and having an electronic component disposed thereon;
• a first insulation plate disposed between the plate and the first circuit board;
• a second insulation plate disposed between the first circuit board and the second circuit board;
• a third insulation plate disposed between the second circuit board and the cover, wherein the third insulation plate is combined with the second insulation plate to form a space for accommodating the second circuit board;
• and
• a clip abutting against the electronic component and combining with the pillow, respectively,
• wherein the pillow further comprises a flat region concavely and inwardly formed thereon, and the clip is stretched into a trough formed between the flat region and the cylinder.
