Embodiment Construction

[0028] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0029] It should be noted that when an element is “fixed” to another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the descrip...

Abstract

The invention discloses a rotor structure and a motor, the rotor structure comprises magnets, the number of the magnets is at least two, and each magnet is provided with a first clamping part; at least two mounting holes are formed in a rotor disc at intervals and correspond to the magnets, first matching parts are arranged on the first side walls of the mounting holes, and the first matching parts are matched with the first clamping parts in a clamped mode; the number of abutting assemblies is at least two, the abutting assemblies correspond to the magnets, each abutting assembly comprises afirst abutting piece, each mounting hole is further provided with a second side wall opposite to the first side wall, and the first abutting pieces abut against the positions between the magnets and the second side walls. During assembly, the magnets are placed in the mounting holes, so that the first clamping parts match with the first matching parts in a clamping manner; afterwards, the first pressing pieces are arranged in the mounting holes, and the two ends of each first pressing piece are pressed against the magnets and the rotor disc respectively, so that the magnets are tightly pressedagainst the interiors of the mounting holes, the assembly is simple, and the operation is easy; due to the pressing effect of the first pressing pieces, the assembling reliability is improved, and looseness is avoided.

Description

technical field [0001] The invention relates to the technical field of motor installation, in particular to a rotor structure and a motor. Background technique [0002] The disc motor is also called the axial permanent magnet motor. The rotor disc of the disc motor is relatively thin, and the circumference of the rotor disc is inlaid with corresponding pole pairs of magnets. The magnets and the sides of the rotor disc are usually fixed by screws or welded on both sides Thin steel sheet pipe string, and glue is applied at the same time to assist in fixing. [0003] The rotor disk is fixed through the cooperation between the hole and the magnet, and the magnet and the hole are easy to loosen. When the rotor rotates at a high speed, it is easy to break down and cause a safety hazard; it is fixed by glue, and the operation is cumbersome. Contents of the invention [0004] Based on this, it is necessary to provide a rotor structure and a motor; the rotor structure is simple to...
