Stator core, single-phase permanent magnet motor and household appliance

Abstract

The invention relates to the technical field of motors, and discloses a stator core, a single-phase permanent magnet motor and a household appliance. The stator core comprises a yoke part and two arm parts which are opposite; each arm part comprises a connecting arm and a polar claw which is arranged at an end of the connecting arm; the polar claws on the two arm parts are opposite to each other to form space for accommodating a rotor; the two arm parts are separately connected to the yoke part through the corresponding connecting arms, and are connected so that the yoke part is located in an extension length range of the connecting arms. The space of an end of a coil winding is utilized, under the condition that the yoke part is located in the extension length range of the connecting arms, the yoke part is connected with the connecting arms, the length of the motor cannot be increased by the settings, and the structure of the motor is compact.

Description

Technical field [0001] The present invention relates to the technical field of motors, in particular to a stator core, a single-phase permanent magnet motor and household appliances. Background technique [0002] The traditional single-phase permanent magnet motor usually consists of a stator core, windings and a rotor, such as figure 1 with 2 As shown, the shape of the stator core is roughly U-shaped, which includes a yoke 1 and two arms 2 separately provided. The yoke 1 is provided with a dovetail slot 1a, and the arm 2 is provided with a dovetail block 2a, This solution connects the yoke 1 and the arm 2 through the cooperation of the dovetail slot 1a and the dovetail block 2a, and the connection and cooperation direction is parallel to the plane where the arm 2 is located, which will increase the length of the stator, and further , To increase the length of the motor. Summary of the invention [0003] The purpose of the present invention is to overcome the problem in the prior...
