Abstract

The invention discloses an insulation frame, a stator and a motor used for household appliances. The insulation frame comprises an upper insulation frame and a lower insulation frame which are installed in a butt joint mode, and a yoke part supporting platform is arranged on the outer side wall of the lower insulation frame. According to the insulation frame, it is avoided that an extra location tool is used in splicing of a stator teeth and a stator yoke, the manufacturing efficiency is improved, and stator manufacturing cost is reduced.

Description

technical field [0001] The invention relates to motor manufacturing technology, in particular to an insulating frame, a stator and a motor for household appliances. Background technique [0002] In order to improve manufacturing efficiency, the stator cores of DC motors used for electric fans and other small household appliances mostly adopt a segmented structure, so that the outer winding method can be used in the winding process, which is convenient for quick winding with automatic winding equipment . [0003] Generally, before winding, it is necessary to install an insulating frame on the stator core to separate the stator core and the stator winding, so as to ensure that the stator core will not become a charged body; among them, the stator winding is generally wound by copper wire The stator core is generally made of laminated silicon steel sheets. For a stator with a block structure, it is the stator teeth made of silicon steel sheets that need to be separated from th...
