Abstract
A permanent magnet fixing device with an outer rotor structure comprises a cylindrical magnet yoke and tile-shaped permanent magnets arranged on the inner surface of the cylindrical magnet yoke. An N electrode of each tile-shaped permanent magnet is adjacent to an S electrode of another tile-shaped permanent magnet adjacent to the tile-shaped permanent magnet. The permanent magnet fixing device is characterized in that through holes are formed at the middle parts of the tile-shaped permanent magnets; conical countersunk holes are formed on the inner sides of the through holes; radially distributed circular holes are formed on the circumference of the cylindrical magnet yoke and are aligned with the through holes on the tile-shaped permanent magnets; an annular groove is formed on the excircle surface of the cylindrical magnet yoke, and the center thereof is aligned with the circular holes; and a countersunk screw is connected with a nut in the annular groove after passing through tile-shaped permanent magnets and the cylindrical magnet yoke. Compared with the prior art, the permanent magnet fixing device has the advantages of simple structure and good process and can ensure that the permanent magnets can be stably fixed on the inner circle surface of the magnet yoke so as not to generate displacement.
Description
Technical field
The utility model relates to a kind of p-m rotor of motor outer rotor structure.
Background technology
The p-m rotor of outer-rotor structure, permanent magnet is generally a watt shape structure, the periphery of permanent magnet and the inner headed face of yoke are close to, for preventing that permanent magnet from displacement occurring under the electromagnetic force effect, generally all use the bonding method of glue to be fixed on the inner headed face of yoke, the problem that this kind rotor exists is: in a single day glue lost efficacy or be aging, and permanent magnet very easily comes off.
Summary of the invention
The purpose of this utility model is to provide a kind of manufacturing process simple, and cost is low, but can guarantee that the permanent magnetism physical efficiency fixedly secures a kind of fixture on the inner headed face of yoke.
The utility model purpose is achieved in that and comprises the cylindrical shape yoke, be arranged on watt shape permanent magnet on the cylindrical shape yoke inner surface, the N utmost point of each watt shape permanent magnet is extremely adjacent with the S of another watt shape permanent magnet that is adjacent, its special feature is: the middle part of watt shape permanent magnet is processed with a through hole, through hole is inboard to be the taper counterbore, the circumference of cylindrical shape yoke has radially-arranged circular hole, the through hole of this circular hole and watt shape permanent magnet over against, the periphery of cylindrical shape yoke is processed with a cannelure, align with circular hole in the cannelure center, sunk screw passes after watt shape permanent magnet and the cylindrical shape yoke with nut in the cannelure and is connected.
For convenient fastening, the cannelure width and the nut opposite side of the periphery of cylindrical shape yoke are measure-alike, and like this, when twisting screw, nut just spins.
Compared with the prior art the utility model has simple in structurely, and good manufacturability can guarantee that the permanent magnetism physical efficiency fixedly secures the advantage that can not occur displacement at the inner headed face of yoke.
