Abstract

The invention provides a stator iron core, a stator assembly, a motor, a food processor and an air supply device; the stator iron core comprises multiple layers of punching sheets, a central through hole is defined by the multiple layers of punching sheets, and the multiple layers of punching sheets are distributed outwards in a stacked mode in the radial direction of the central through hole. Thestator iron core provided by the invention comprises the multiple layers of punching sheets, and the multiple layers of punching sheets are laminated and distributed in the radial direction of the stator iron core, so that the magnetic resistance of the stator iron core can be effectively reduced, the magnetic loss is reduced, and the motor efficiency is further improved; therefore, the magneticcircuit of the stator core is shorter, the motor can be flatter and thinner, and the miniaturization of the motor can be realized.
