Problems solved by technology

[0026] However, since the insulator 29 is arranged on the upper and lower surfaces of the core 37 inside the coil 38 except for the portion where the coil 38 is wound, the coil 38 of the stator of the motor of the washing machine of the related art is exposed outside the stator 32
[0027] Therefore, there is a risk of electric shock from the power applied to the coil 38, as well as a risk of damage to the coil 38 during transportation, assembly and maintenance of the stator 32

Abstract

The present invention is related to a motor (60) for a washing machine, in which an insulator (116) structure is changed so as not to expose a coil (114) to an outside of the stator (110) for preventing accidents of electric shock caused by negligence of safety from occurring in advance, to enhance safety of the motor (60), and damage to the coil (114), and which enables to reduce magnetic attraction force and prevent interference between the stator (110) and the rotor (120) caused by the non-uniform gap between the stator (110) and the rotor (120). To achieve this, the present invention provides a motor (60) for a washing machine including a stator (110) including a substantially annular core (112) having a stack of steel pieces (1129), a coil (114) wound on the core (112) having an AC power applied thereto, and an insulator (116) mounted on an outside surface of the core (112), the insulator (116) having one edge extended to cover the coil (114), wherein a plurality of the coils (114) are wound along the circumference of the core (112), and connected in parallel.

Description

technical field [0001] The present invention relates to an outer rotor type induction motor of a washing machine, and more particularly, to an outer rotor type induction motor of an improved structure for a washing machine, which improves performance, ensures safety, and prevents damage to stator coils. Background technique [0002] Generally, a washing machine washes clothes through steps of washing, rinsing, centrifugal spinning, drying, etc., and removes dirt from clothes and bedding (hereinafter referred to as clothes) held in a washing tub by the action of water and detergent. [0003] FIG. 1 illustrates a section of a washing machine to which a related art motor is applied, and FIG. 2 illustrates a perspective view of a related art washing machine motor. [0004] Referring to FIG. 1 , a washing machine of the related art is provided with a cabinet 2 forming its exterior; an outer tub 4 with a supporting member 4a suspended inside the cabinet 2, which has a space for ho...
