Problems solved by technology

[0002] The traditional single-phase permanent magnet motor usually consists of stator core, winding and rotor, such as figure 1 and 2 As shown, the shape of the stator core is roughly U-shaped, which includes a yoke 1 and two separate arms 2, the yoke 1 is provided with a dovetail slot 1a, and the arm 2 is provided with a dovetail block 2a, In this solution, the yoke 1 and the arm 2 are connected through the cooperation of the dovetail groove 1a and the dovetail block 2a, and the connection and matching direction is parallel to the plane where the arm 2 is located, which will cause the length of the stator to increase, and further , so that the length of the motor increases

Embodiment Construction

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0034] In the present invention, the terms "first", "second", ..., etc. are only used to distinguish different technical features, and are not used to limit the priority of the technical features. Where necessary, these technical features The effect that can be achieved is basically the same.

[0035] Reference Figure 3 to Figure 11 As shown, the present invention first provides a stator core, which includes a yoke 1 and two opposite arm portions 2. The arm portion 2 includes a connecting arm 21 and a pole claw 22 arranged at the end of the connecting arm 21. The pole claws 22 on the arm portion 2 are opposed to each other to form a space for accommodating the rotor. The tw...

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...
