Abstract
The utility model relates to a permanent magnet motor rotor having a function of raising rotating speed of a motor, comprising a rotor and a tile type permanent magnet; wherein the tile type permanent magnet is coaxially and uniformly bonded on an outer wall of the rotor, a permanent magnet sheath is coaxially sleeved on an outer wall of the tile type permanent magnet, and the material of the permanent magnet sheath is stainless steel. The permanent magnet motor rotor of the utility model has the advantages of simple structure, scientific and reasonable design, low cost, capacity for effectively raising the rotating speed of the motor, and capacity for raising the performance of the permanent magnet motor.
Description
Technical field
The utility model belongs to the rotor field, and especially a kind of have a permanent magnet machine rotor that improves the motor speed performance.
Background technology
Tile type permanent magnet in magneto adopts adhesive structure usually, namely with glue, permanent magnet is fastened on the rotor core surface.The shortcoming of this structure is that permanent magnet can not bear larger centrifugal force, and motor speed is restricted.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of permanent magnet machine rotor that improves the motor speed performance that has is provided, this rotor structure for permanent magnet motor is simple, design science reasonable, cost is lower, effectively improve motor speed, promotes the magneto performance.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of permanent magnet machine rotor with raising motor speed performance comprises rotor and tile type permanent magnet, coaxial uniform being bonded on the rotor outer wall of this tile type permanent magnet, and it is at tile type permanent magnet outer wall coaxial package one permanent magnet sheath.
And described permanent magnet jacket thickness is less than 0.5mm.
Advantage of the present utility model and beneficial effect are:
Originally has the permanent magnet machine rotor that improves the motor speed performance, comprise rotor and tile type permanent magnet, coaxial uniform being bonded on the rotor outer wall of this tile type permanent magnet, it is at tile type permanent magnet outer wall coaxial package one permanent magnet sheath, this permanent magnet sheath material is stainless steel, this is simple in structure, design science is reasonable, cost is lower, effectively improve motor speed, promotes the magneto performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of permanent magnet machine rotor with raising motor speed performance, comprise rotor 1 and tile type permanent magnet 2, coaxial uniform being bonded on the rotor outer wall of this tile type permanent magnet, it is at tile type permanent magnet outer wall coaxial package one permanent magnet sheath 3, this permanent magnet sheath material is stainless steel, and the permanent magnet jacket thickness is less than 0.5mm.
Be enclosed within on the rotor that is stained with the tile type permanent magnet after permanent magnet sheath heating of the present utility model, the permanent magnet sheath but is fastened on permanent magnet the rotor outer wall surface afterwards, this fastening structure successful, and motor speed no longer is so limited.
