Abstract

The invention generally relates to the technical field of motors, in particular to a stator punching sheet, a stator core, a stator, a motor and an air conditioning device. The stator punching sheet comprises a plurality of punching sheet single bodies which are connected in sequence, and a connecting bridge is arranged between every two adjacent punching sheet single bodies; grooves are formed between the radial outer side of the connecting bridge and two adjacent punching sheet single bodies, the connecting bridge comprises a first side end face located on the radial outer side and a secondside end face located on the radial inner side, and the first side end face comprises a first buffer surface protruding towards the radial outer side. The second side end face comprises a second buffer surface recessed towards the outer side in the radial direction, and the first buffer surface and the second buffer surface are used for bending buffer of the connecting bridge to reduce damage of the connecting bridge during circle forming. According to the scheme, the stator punching sheet can be folded reversely, wire winding is convenient, and the wire winding full tank rate is improved, andthe first buffer surface can reduce the bending of the connecting bridge when the stator punching sheet is reversely folded.

Description

technical field [0001] The present application generally relates to the technical field of motors, and in particular, relates to a stator punch, a stator core, a stator, a motor and an air conditioner. Background technique [0002] With the country's requirements for the energy efficiency level of household products such as air conditioners and refrigerators, and the improvement of people's living standards, the compressor is the core component of the refrigeration device. The chain stator punching in the prior art includes multiple sequentially connected punching units. body, and two adjacent punching pieces are connected by a yoke connecting bridge. [0003] However, the existing connecting bridge has a straight-edge structure, which is easily deformed and damaged when the stator core is rounded, and the chain-type stator punches are easily broken due to reciprocating bending, and the structural strength of the connecting bridge is weak. Contents of the invention [000...
