Abstract

The invention provides a rotor structure and a motor with the same. The rotor structure comprises a magnetic ring and a rotor disc, wherein the magnetic ring is connected with the rotor disc, the surface of the rotor disc is provided with convex edges, the convex edges extend outwards in the radial direction of the rotor disc, and the convex edges are used for increasing the width of the magneticcircuit in the thickness direction of the magnetic ring. The convex edges are arranged on the rotor disc, so that the width of the magnetic circuit formed on the rotor disc can be effectively increased. Therefore, the situation that the magnetic ring magnetic circuit is easily saturated can be avoided, the reliability of the rotor structure is effectively improved, and the performance of the motorwith the rotor structure is improved.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure and a motor having the same. Background technique [0002] In the prior art, the permanent magnet rotor core of conventional axial field motors is usually a disc-shaped structure. In order to save materials, the thickness of the chassis is often designed to be relatively thin, the magnetic circuit will be relatively narrow, and magnetic saturation is likely to occur, causing motor Poor performance issues such as figure 1 As shown, 11' is a permanent magnet, 20' is a rotor disc, S is the S pole of the permanent magnet, and N is the N pole of the permanent magnet. Contents of the invention [0003] The main purpose of the present invention is to provide a rotor structure and a motor with it, so as to solve the problem of poor motor performance in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invent...
