Abstract

The invention discloses an outer rotor motor, which comprises a stator component, a rotor component (12) and a rotating shaft (7), wherein the rotor component (12) is sleeved outside the stator component; the rotor component (12) and the rotating shaft (7) are arranged and connected together; and the rotating shaft (7) is supported and arranged on the stator component through a bearing (6). The outer rotor motor is characterized in that the stator component comprises a stator core (1) and a coil winding (2); the coil winding (2) is wound on the stator core (1); an insulating shell (3) is injection-molded outside the stator core (1) and the coil winding (2); and the insulating shell (3) encloses the stator core (1) and the coil winding (2) to realize the isolation from the external world. The invention has good insulator performance, solves the problems of water resistance, dust prevention, corrosion resistance, the prevention of the oxidation of nonferrous metal wires, and end insulation, improves the safe reliability, reduces the weight of the motor and the cost for the motor, improves the cooling effect of a stator, reduces the temperature increase of the motor, and has more convenient motor installation and higher production efficiency.

Description

Technical field: [0001] The invention relates to an outer rotor motor. Background technique: [0002] At present, the stator structure in an external rotor motor includes an end cover, a stator core, a coil winding and an insulator. The coil winding is wound on the stator core, and an insulator is installed on the coil winding exposed at both ends of the stator core. Then it is pressed tightly with the aluminum alloy end cover, and the bearing chamber and screw holes are processed on the aluminum alloy end cover. The bearing chamber is used to support the rotation of the motor, and the screw holes are used to install and fix the stator parts. This stator structure has the following disadvantages: no waterproof, no anti-oxidation, no dustproof, poor insulation performance, heavy weight, high cost, poor integrity, many production processes, low production efficiency, many bearing chamber processing procedures, bearing chamber Dimensional accuracy is low.
