Abstract

The invention discloses a motor, a household appliance and a manufacturing method of the motor. The motor comprises a rotor iron core which comprises a shaft ring part and a plurality of fan-shaped parts arranged around the shaft ring part at intervals, wherein a containing groove is formed between every two adjacent fan-shaped parts, and the shaft ring part is provided with a shaft hole; and a stator iron core which sleeves the periphery of the rotor iron core. The magnet is arranged in the containing groove, and the axial length of the magnet is larger than or equal to the axial length of the rotor iron core; the end face covering part covers the end face of the rotor iron core so as to cover and wrap the magnet, so that the axial fixing effect on the magnet is achieved, and the stability of the motor performance is guaranteed; and the length of the rotor iron core in the axial direction of the shaft hole is set to be larger than the length of the stator iron core in the axial direction, the first end of the rotor iron core protrudes out of or is flush with the first end of the stator iron core, and the second end of the rotor iron core protrudes out of the second end of the stator iron core, so that the performance of the motor can be improved with relatively low cost.

Description

[0001] This application is a divisional application with the filing date of "2019.09.26", the application number of 201910920218.1, and the application title of "Motors, Household Appliances, and Motor Manufacturing Methods". technical field [0002] The present application relates to the technical field of motors, in particular to a motor, a household appliance and a method for manufacturing the motor. Background technique [0003] In recent years, DC brushless motors for air-conditioning fans are increasingly pursuing high efficiency and miniaturization. Some manufacturers gradually adopt rotors with tangential built-in magnet structures to replace traditional surface-mounted magnet rotors. In the production process of the tangential built-in magnet rotor structure, there are still some problems in the magnetization of the magnet. At present, there are mainly two methods for tangential built-in magnet magnetization. The first method is: the magnet is magnetized in pieces f...
