The present disclosure provides a motor including a stator, a rotor and a first circuit board. The stator includes a winding assembly including a plurality of coils. A conductive element is extended out from the winding assembly and is electrically connected to a first electrical connector. The first electrical connector penetrates through a pillow of the stator and is electrically connected to the first circuit board. The motor further includes a second circuit board electrically connected to the first circuit board, and a first insulation plate, a second insulation plate and a third insulation plate for fixing and protecting the circuit boards. The motor also includes a clip for fixing and heat dissipating an electronic component disposed on the second circuit board.

Motor

A fan rotor includes a rotating shaft, a metal body, at least one rotor magnet and a vane wheel. The metal body has at least one top surface, at least one cylindrical portion and at least one connecting portion. The top surface is disposed at an end of the cylindrical portion, and the rotating shaft is disposed in the cylindrical portion and connected to the top surface of the cylindrical portion. The connecting portion is formed at the other end of the cylindrical portion and extended from an outer wall of the opening in a direction away from the rotating shaft. The rotor magnet is disposed around an inner wall surface of the cylindrical portion. The vane wheel is detachably connected to the metal body through the connecting portion.

Fan rotor

A stator seat of a motor includes a pillow, a connector, a waterproof element and cables. A sleeve is extended from the pillow. A cap covers the pillow and sleeve. A control chamber is formed and enclosed by the cap and pillow. The pillow has a through hole communicated with the control chamber. The connector corresponsive to the through hole is installed in the control chamber and includes a first connecting structure. The waterproof element covers the through hole and includes an annular groove and an O-ring clamped between the waterproof element and pillow, and a second connecting structure. The first and second connecting structures are passed through the through hole. An insertion hole is penetrated through the waterproof element. Each of the cables has an end connected to the connector and the other end passed out from the pillow through the insertion hole and through hole.

Stator seat of motor, and connector waterproof structure thereof

A motor stator includes a bobbin bracket, a modular mounting bracket, and a modular change box. The bobbin bracket includes a plurality of bobbins circularly disposed in a radial pattern. The modular mounting bracket is disposed on the bobbin bracket. The modular mounting bracket is formed with a first slide structure. The first slide structure is perpendicular to an axial direction of the bobbin bracket. A sensing circuit board is disposed in the modular change box. The modular change box is formed with a second slide structure. The second slide structure is perpendicular to the axial direction of the bobbin bracket and slidably connected into the first slide structure, so as to assemble the modular change box to the modular mounting bracket along a radial direction of the bobbin bracket.

Motor stator

A motor rotor includes a cylindrical housing, a positioning ring and a plurality of magnets. The cylindrical housing includes a plurality of securing holes. The positioning ring is disposed on the cylindrical housing. The positioning ring is disposed with a plurality of flexible ribs and a plurality of securing ribs disposed corresponding thereto. Each of the flexible ribs is radially pressable. The flexible ribs are disposed in the cylindrical housing, and each of the securing ribs is inserted in a respective corresponding one of the securing holes. The magnets are disposed in the cylindrical housing. Each of the magnets is clamped between the adjacent flexible ribs and is arranged annularly along an inner wall of the cylindrical housing, so as to facilitate assembly.
