Stator core for roller washing machine motor

Abstract

The invention discloses a stator core for a roller washing machine motor, and the stator core is formed by the jointing of a plurality of iron core blocks. Each iron core block is formed by the lamination of iron core block sheets, and each iron core block sheet consists of a strip-shaped connecting piece and a plurality of fins which are disposed at a side of the connecting piece and used for winding. Each connecting piece is located at the central parts of two fins, and is provided with a groove, wherein the direction of the groove is opposite to the extending direction of the fins. One side edge of each groove is provided with a recessed part, and the other side edge is provided with a bulged part corresponding to the recessed part. When the iron core blocks need to be bent, the stator core is easy to bend because of the existing of the avoiding grooves.

Description

technical field [0001] The invention relates to a stator iron core of a drum washing machine motor, and belongs to the technical field of accessories of washing machines. Background technique [0002] Generally speaking, the drum washing machine is a household appliance that uses the surface activity of detergent, the friction of water flow generated when the drum rotates, and the impact of the drum on the washing to remove various stains on the washing. The rotational force of the drum is usually provided by a motor including a stator, a rotor, coils and the like. However, the stator iron core used in the original drum washing machine motor is directly stamped, resulting in a huge waste of raw materials and an increase in cost. The utility model patent with the notification number CN202798179U discloses a stator core of a drum washing machine motor, and the stator core is composed of 3 to 4 segmented cores spliced ​​together. The processing method is as follows: firstly p...

Problems solved by technology

The processing method is as follows: firstly punch and press the strip-shaped iron chips, then stack several strip-shaped iron chips into a straight strip-shaped block iron core, and then use the circular tooling fixture to bend the straight strip-shaped block iron core The segmented iron core in the shape of an arc, and then 3 to 4 segmented iron cores in the shape of an arc are connected end to end and shaped to obtain the stator core. The disadvantage of this structure is that the straight When the bar-shaped segmented core is bent into an arc-shaped segmented core, there is a problem of difficulty in bending
