Abstract

A method of assembling a motor unit (55), the method including mounting of the motor unit (55) on a washing machine body, where the motor unit (55) has a stator holding part (33) to be mounted on the washing machine body, a stator (5a), and a rotor (5b) having a magnet and fitted to a rotating shaft (4a) journalled on the washing machine body. The method has a first step for assembling the stator (5a) and the rotor (5b), the stator (5a) being in a state where it is not yet mounted on the stator holding part (33), the rotor (5b) being in a state where it is not yet mounted on the rotating shaft (4a) and has magnetized magnets, a second step for mounting the rotor (5b) on the rotating shaft (4a), and a third step for mounting the stator (5a) on the stator holding part (33). Assembly of the motor unit (55) to be mounted on the washing machine can be easily made with high workability and without requiring skill.

Description

technical field [0001] The present invention relates to a method of assembling a motor unit, a method of assembling a washing machine equipped with the motor unit, a motor unit of a washing machine using these assembling methods, and a washing machine equipped with the motor unit having a stator attached to the washing machine , and a rotor with magnets mounted on a drive shaft supported by bearings on the washing machine. Background technique [0002] A conventional washing machine equipped with an electric motor of the washing machine has, for example, Figure 9 , Figure 10 The structure of front-loading-type washing machine 100 (hereinafter referred to as washing machine 100 ) as shown is shown.
