Embodiment Construction

[0010] Such as image 3 As shown, the outer rotor type motor of the washing machine provided by the present invention includes: a rotating frame 21 connected to the drive shaft 26 at the center; a stator 24 located inside the rotating frame 21 and fixedly arranged on the lower side of the motor cover 27; and The rotor 22 is located on the inner side of the rotating frame 21, is arranged radially opposite to the stator 24, and is made of permanent magnets. Corresponding connecting holes 30 are respectively formed on the stator 24 and the motor cover 27 , and one end of the screw 28 is fastened with a nut 29 after passing through the connecting holes 30 , so that the stator 24 can be fixed on the lower side of the motor cover 27 . In addition, in order to fix the rotor 22 on the inner peripheral surface of the rotating frame 21, the upper end of the rotating frame 21 is inwardly The shape is bent to press the upper end of the rotor 22. A coil 25 is wound on the outer peripher...

Abstract

The motor includes following parts: stator enwound wire of making current passing through; rotor setup outer side of the stator, and keeping up a certain internal between rotor and stator, rotor is rotated when stator is connected to power source; rotative frame connected to rotor, the frame including an integrated connection part for fixing the rotor. In the invention, rotor is fixed on internal side face of rotative frame without need of individual connection part. Thus, structure of the motor is simplified, and assembling steps and time are reduced. The invention reduces defective rate.

Description

technical field [0001] The present invention relates to an outer rotor type motor installed in a washing machine, in particular to an outer rotor type motor of a washing machine in which the rotor of the outer rotor type motor can be directly fixed by a rotating frame without a separate connecting part. Background technique [0002] Generally speaking, a washing machine is a device for washing, rinsing, and dehydrating clothes by using a washing tub or a mechanical rotational force generated by a pulsator arranged at the bottom of the washing tub. The method of transmitting the power of the driving motor in the washing machine to the washing tub or the pulsator mainly includes: the indirect transmission method through the motor pulley; Rotation A method of directly transmitting the rotational power of a motor to a rotating shaft. figure 1 It is a sectional view of the longitudinal structure of a washing machine in the prior art. figure 2 It is a sectional view of an outer...
