Abstract

The invention relates to the field of fan motor technology, and more particularly to a DC three-phase brushless motor for a household fan. The DC three-phase brushless motor includes a winding group, a magnetic frame, a bearing and a PCB, and also includes a magnet and a base. The magnetic frame is provided with a shaft core. The winding group is arranged on the shaft core. The magnetic frame is arranged on the outer surface of the winding group. The magnet is located between the magnetic frame and the winding group. The winding group is connected with the PCB. The base is arranged in the shaft core in a sleeving manner and in an inner hole of the winding group in a penetrating manner. One end of the base is in contact with the magnetic frame, and the other end of the base protrudes from the PCB. The bearing is arranged in the shaft core in a sleeving manner and mounted in the base. The invention is capable of converting an AC voltage of 220 V to a DC voltage of 5V, and ensures that the invention can be driven by the 5V voltage to achieve the running speed and air pressure and volume of an AC motor, thereby saving energy and also meeting the cooling effect.

Description

technical field [0001] The invention relates to the technical field of fan motors, in particular to a DC three-phase brushless motor for household fans. Background technique [0002] At present, the existing household fans all use 220V alternating current (AC) motors, which have high power consumption, excessive power loss, and excessive noise, which can no longer meet the high standard requirements of users in terms of power supply; and the current household The space for installing the motor of the fan is limited, the heat dissipation effect is poor, and the service life of the motor is easily affected. [0003] And the existing direct current (DC) motor that is used for fan can only be used for some miniature, miniature fans, and the power that provides is limited, can't be used for the big household fan of power. Contents of the invention [0004] The purpose of the present invention is to provide a DC three-phase brushless motor that can convert AC current into 5V DC...
