Description
Technical field
The utility model relates to technical field of motors, especially a kind of energy-saving electric machine.
Background technology
Along with the development of China's economic, the demand of the energy is constantly increased, because energy prices rise steadily, and the energy resource consumption meeting causes environmental pollution, energy-saving and cost-reducingly becomes the problem that government department and various circles of society all take much count of.Present Chinese motor account for national power consumption 60% and industrial electric weight 80%, under the commercial power intense situation, developing energy-saving motor becomes the task of top priority.Because magneto has better energy-saving effect, many enterprises and research institution conduct in-depth research this, and have developed the magneto product of various satisfied different actual demands.But in existing magneto product, structural design is reasonable not, and production efficiency is low, is difficult to fully satisfy the demand of practical application.
Summary of the invention
For the deficiencies in the prior art, the utility model provides that a kind of production efficiency is high, the energy-saving electric machine of good combination property.
the technical solution of the utility model is: a kind of energy-saving electric machine, comprise protecgulum, middle cover, bonnet, rotor and stator, it is characterized in that: described middle cover is fixedly connected with bonnet with protecgulum respectively, middle cover is the tubular of hollow, the middle cover inboard is provided with stator, be provided with a plurality of line embedding grooves be used to winding is set in stator, rotor comprises rotating shaft, rotor core and permanent magnet, described rotating shaft is arranged in rotor core by bearing, and the rotating shaft front end stretches out outside protecgulum, the rotating shaft rear end is stretched in bonnet, the permanent magnet of being made by rare earth permanent-magnetic material is being inlayed in the rotor core outside, permanent magnet is comprised of a plurality of arc-shaped permanent magnet piecemeals.
Described middle cover two ends are equipped with a plurality of louvres.
Described permanent magnet is rubidium iron boron magnet ring.
The beneficial effects of the utility model are:
1. permanent magnet can use rubidium iron boron magnet ring, and coercive force is high by adopting, the strong rare earth permanent-magnetic material of anti-degaussing ability, can reduce volume and the quality of motor, has greatly improved the conversion efficiency of motor;
By in cover and set up a plurality of louvres, can effectively reduce the temperature of intraware, can make motor stable, noise is little, and long service life;
3. reasonable in design, simple in structure, all parts is easy to assembling, and production efficiency is high, good combination property.
Description of drawings
Fig. 1 is the structural representation of energy-saving electric machine described in the utility model.
In figure, 1-protecgulum, 2-middle cover, 3-bonnet, 4-rotor, 5-stator, 21-louvre, 41-rotating shaft, 42-rotor core, 43-permanent magnet, 51-line embedding groove.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
as shown in Figure 1, a kind of energy-saving electric machine, comprise protecgulum 1, middle cover 2, bonnet 3, rotor 4 and stator 5, middle cover 2 is fixedly connected with bonnet 3 with protecgulum 1 respectively, middle cover 2 is the tubular of hollow, middle cover 2 two ends are equipped with a plurality of louvres 21, when motor moves, the heat that produces on each assembly can effectively be distributed to the outside by cross-ventilation, thereby motor is operated steadily, noise is low, long service life, middle cover 2 inboards are provided with stator 5, be provided with a plurality of line embedding grooves 51 be used to winding is set in stator 5, rotor 4 comprises rotating shaft 41, rotor core 42 and permanent magnet 43, rotating shaft 41 is arranged in rotor core 42 by bearing, and rotating shaft 41 front ends stretch out outside protecgulum 1, rotating shaft 41 rear ends are stretched in bonnet 3, the permanent magnet 43 of being made by rare earth permanent-magnetic material is being inlayed in rotor core 42 outsides, permanent magnet 43 is comprised of a plurality of arc-shaped permanent magnet 43 piecemeals, in the present embodiment, permanent magnet 43 is rubidium iron boron magnet ring, by adopting coercive force high, the strong rare earth permanent-magnetic material of anti-degaussing ability, make the size of motor little, quality is light, and has higher conversion efficiency.Therefore, the utlity model has good structural design, all parts is easy to assembling, and production efficiency is high, and good combination property is a kind of magneto product of high-quality.
That describes in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.
