Motor iron core structure

Abstract

The invention discloses a motor iron core structure. The motor iron core structure comprises a core body (10), the core body (10) comprises annular yoke parts (11), and tooth parts (12) are annularlydistributed outside the yoke parts (11); the tooth parts (12) are of a cuboid structure, the tooth parts (12) sleeves insulating shells (20) in the radial direction, and winding wires are wound aroundthe insulating shells (20). Insertion pieces (30) are used for limiting the radial positions of the insulating shells (20), axial grooves (13) are formed in the side faces of the tooth parts (12), and the grooves (13) are matched with the insertion pieces (30). The motor iron core structure has the characteristics of being easy to assemble and good in stability.

Description

technical field [0001] The invention relates to a large washing machine motor iron core, in particular to an independent winding type motor iron core. Background technique [0002] Some washing machine motors have the structure of inner stator and outer rotor. Among them, the rotor is similar to a disc structure, and the magnets are distributed on the inner ring wall of the disc, and the stator includes a ring-shaped iron core body, and the teeth are distributed in a ring shape outside the iron core, and the teeth have umbrella-shaped tops, and the teeth are wound with windings through an insulating structure. Wire. The iron core of the conventional structure often adopts manual embedding, which leads to high work intensity, low efficiency, and easy to cause quality problems. Therefore, the automatic embedded wire stator core came into being. The iron core of this structure is mainly divided into two forms. One is to divide the iron core body into several sectors, and eac...

Problems solved by technology

The latter has better assembly difficulty and manufacturability, but there are corresponding problems in the insert structure

If there is an interference fit between the insert and the groove, the friction force will be large when the insert is assembled. If the insert and the groove are not an interference fit, the insert will not be strong enough and there is a risk of falling off under vibration conditions
