Abstract
The invention discloses a kind of motor, including stator core and rotor core, it is characterised in that: one of axial length and the axial length of rotor core of the stator core are design standard length, another is longer than design standard length.
Description
Technical field
The present invention relates to a kind of stator core motor different from rotor core length.
Background technique
In production and living, common middle-size and small-size motor applications are very extensive, stator and rotor in this motor
Length is identical, if axile displacement does not occur for stator core and rotor core, i.e. stator core is matched with rotor core in assembly
It closes length to be consistent with design value, the performance of motor can be played fully.
Summary of the invention
The object of the present invention is to provide a kind of motor, can make the stator core and rotor core length of fit of motor
It is identical as Theoretical Design value.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of motor, including stator core and rotor
Iron core, one of axial length and the axial length of rotor core of the stator core are design standard length, another
It is a to be longer than standard design length.
Using motor of the invention, since one of stator core and rotor core axial length are designed greater than standard
Length causes the two length of fit to change it is possible to prevente effectively from rotor core axile displacement occurs for stator core, thus
Stablize motor performance.
Detailed description of the invention
Fig. 1 is the broken section structural schematic diagram of the embodiment of the present invention 1.
Specific embodiment
As shown in Figure 1, a kind of motor, including stator core 10 and rotor core 20,
One of axial length and the axial length of rotor core 20 of the stator core 10 are design
Full-length, another is longer than design standard length.One of stator core 10 or rotor 20 are set as standard design
Length meets the prime design requirement of motor, and two end faces for being longer than the iron core of standard design length protrude from standard respectively and set
One segment length of iron core both ends of meter can make up the axial mistake that the external factor such as dimensional tolerance and rigging error may cause
Position guarantees that the length of fit of stator core 10 and rotor core 20 is design standard length.Below in conjunction with attached drawing to of the invention
Two embodiments elaborate.
Stringent control installation accuracy is needed when assembling compared to the stator core of conventional motors and rotor core, it is of the invention
Motor in assembly, due to longer iron core both ends there are surplus it is more, installation accuracy requires lower, therefore motor exists
It is also more convenient when assembly.
For those skilled in the art, technical solution documented by foregoing embodiments can still be carried out
Modification or equivalent replacement of some of the technical features, it is all within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
