Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a permanent magnet motor and an air conditioner, wherein the permanent magnet motor comprises a rotor and a stator arranged in a way of surrounding the rotor; the ratio D1 / D2 of the outer diameter D1 of the rotor to the outer diameter D2 of the stator is 0.56 to 0.63. The technical scheme has the advantage that the efficiency of the permanent magnet motor can be improved.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a permanent magnet motor and an air conditioner. Background technique [0002] A permanent magnet motor is a motor that uses permanent magnets to establish a magnetic field. Compared with an electric excitation motor, a permanent magnet motor eliminates the excitation winding and excitation power supply. It has simple structure, reliable operation, no excitation system loss, and the size and form of the permanent magnet motor Flexible and diverse, it has a wide range of applications in air conditioners, especially fans of air conditioners. According to the different arrangements of permanent magnets, permanent magnet motors can be divided into two types: surface mount type and built-in type. Among them, the built-in type permanent magnet motor is compared with the surface mount type permanent magnet motor by placing more permanent magnets to improve The air-gap magnetic dens...
