Stator punching sheet, stator iron core, stator, motor and air conditioning device

The invention provides a stator punching sheet, a stator iron core, a stator, a motor and an air conditioning device, relates to the technical field of motors, and solves the technical problem of relatively high magnetic energy loss of a chained stator punching sheet at a yoke joint in the prior art. The stator punching sheet comprises a plurality of punching sheet units which are connected in sequence, wherein the two adjacent punching sheet units are connected through a yoke connecting bridge; and when the plurality of punching sheet units form the stator punching sheet by circle forming, the yoke connecting bridge can be positioned on the outer side of an outer circle of the stator punching sheet formed after circle forming. According to the stator punching sheet, the two adjacent punching sheet units can have sufficiently long fitting surfaces during circle forming, so that the magnetic energy loss is reduced to the minimum, and the performance of the motor is further improved. 本发明提供了一种定子冲片、定子铁芯、定子、电机及空调装
