Abstract
The utility model belongs to the electromechanical equipment technology field, and provides an improved structure of a rotor of a motor comprising a rotating shaft and an iron core. The iron core is formed by overlapping silicon steel plates. Upper permanent magnets and lower permanent magnets are disposed in the iron core, and are arranged along a peripheral direction of the iron core, and can rotate along the rotating shaft. The number of the upper permanent magnets is equal to the number of the lower permanent magnets. The utility model is advantageous in that the upper permanent magnets and the lower permanent magnets are arranged along the peripheral direction of the iron core, and the adjacent polarities are opposite to each other, therefore the magnetic leakage phenomenon can be effectively reduced, the utilization rate of the magnets can be improved, and the operation stability of the motor can be guaranteed.
Description
Technical field
The utility model belongs to the electromechanical equipment technical field, and the rotor that relates in a kind of motor improves structure.
Background technology
Motor is to be the instrument of mechanical energy with electric energy conversion according to the law of electromagnetic induction, its composition generally comprises stator, rotor, support and end cap, stator is the stationary part of motor, be mainly used to produce magnetic field, rotor is the rotating part of motor, mainly is to produce electromagnetic torque, and the rotor in the existing motor is because structure arranges difference, can often produce magnet leakage field phenomenon, the utilance of magnet is lower.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple and reasonable, and the rotor in the high motor of magnet utilance improves structure.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the rotor in a kind of motor improves structure, comprise rotating shaft and iron core, described iron core is formed by silicon steel plate stacking, institute's Adopts measure is: be furnished with along rotating shaft rotation in the described iron core and along upper permanent magnet and the lower permanent magnet of circumferential arrangement unshakable in one's determination, described upper permanent magnet is identical with the quantity of lower permanent magnet.
Specifically comprise for optimizing the such scheme Adopts measure:
Rotor in above-mentioned motor improves in the structure, offers storage tank on the described iron core, and described upper permanent magnet and lower permanent magnet are embedded in the iron core by storage tank, and described upper permanent magnet is positioned at skin unshakable in one's determination, and lower permanent magnet is positioned at internal layer unshakable in one's determination.
Rotor in above-mentioned motor improves in the structure, and described two adjacent upper permanent magnet polarity are opposite, and two adjacent lower permanent magnet polarity are opposite, and are N, the setting of S interval.
Rotor in above-mentioned motor improves in the structure, and the magnetic of described upper permanent magnet is greater than the magnetic of lower permanent magnet.
Compared with prior art, the utility model has the advantage of by upper permanent magnet and the lower permanent magnet of layout along circumferential arrangement unshakable in one's determination, and the adjacent polarity that makes is opposite, has so effectively reduced the leakage field phenomenon, improve the utilance of magnet, guaranteed the stability of motor operation.
Description of drawings
Fig. 1 is that the rotor in this motor improves structural representation.
Among the figure, rotating shaft 1; Unshakable in one's determination 2; Upper permanent magnet 3; Lower permanent magnet 4; Storage tank 5.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the rotor in this motor improves structure, comprises rotating shaft 1 and iron core 2, and described unshakable in one's determination 2 silicon steel plate stackings by the 0.3-0.5 millimeter form, and has guaranteed like this reliability of motor operation.
Be furnished with in unshakable in one's determination 2 along rotating shaft 1 rotation and along upper permanent magnet 3 and the lower permanent magnet 4 of 2 circumferential arrangement unshakable in one's determination, the magnetic of upper permanent magnet 3 is greater than the magnetic of lower permanent magnet 4, two adjacent upper permanent magnet 3 polarity are opposite, two adjacent lower permanent magnet 4 polarity are opposite, and are N, the setting of S interval, can effectively reduce the leakage field phenomenon like this, improve the utilance of magnet, upper permanent magnet 3 is identical with the quantity of lower permanent magnet 4, and in the present embodiment, the quantity of upper permanent magnet 3 and lower permanent magnet 4 is 10.
In order conveniently to install and fix, offer storage tank 5 on unshakable in one's determination 2, upper permanent magnet 3 and lower permanent magnet 4 are embedded in unshakable in one's determination 2 by storage tank 5, and upper permanent magnet 3 is positioned at unshakable in one's determination 2 skin, lower permanent magnet 4 is positioned at unshakable in one's determination 2 internal layer, so just saved every accessories such as magnetic copper sheathings, effectively reduced production cost.
