Embodiment Construction

[0028] In this application, unless stated to the contrary, the used orientation words such as "up, down, left, and right" generally refer to up, down, left, and right with reference to the drawings. "Inner and outer" refer to inner and outer relative to the outline of the part itself. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0029] The application provides a rotor, such as Figure 1-9 As shown, it includes a rotating shaft 100 , a magnet 300 , a rotor core 200 , and an overmolding portion 400 for covering the rotor core 200 . At le...

Abstract

The invention relates to the electromechanical field, and discloses a rotor and a motor. The rotor comprises a rotating shaft (100), a magnet (300), a rotor core (200), a plastic-coated part (400) used for coating the rotor core (200), wherein at least part of the rotor core (200) is exposed from the plastic-coated part, thereby facilitating the improvement of the magnetism gathering ability of the rotor, being capable of reducing the plastic consumption of the plastic-coated part, and improving the performance of the plastic-packaged rotor.

Description

technical field [0001] This application relates to the electromechanical field, in particular to rotors and motors. Background technique [0002] Because of its simpler structure, more reliable operation, higher efficiency and power density, brushless DC motors are increasingly used in various electrical devices. Among them, the rotor magnetic field and the stator magnetic field are coupled to generate torque, the stator generally generates a magnetic field by passing current through the winding, and the rotor generally provides a magnetic field by a permanent magnet. According to the position where the rotor pole structure is installed, it can be divided into surface type and built-in type. Among them, the tangential magnet built-in rotor is an important direction. [0003] In order to fix the magnets, plastic packaging is usually used, but the plastic packaging easily affects the magnetic gathering ability of the rotor. How to improve the plastic packaging structure and ...
