Description
Technical field
The utility model relates to technical field of motors, especially a kind of safe motor.
Background technology
Motor is the conversion equipment of realizing electric energy and mechanical energy or mechanical energy and electric energy, is used widely in fields such as industrial or agricultural, building and public utilities.At 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 simple in structure, more energy-conservation characteristics; many enterprises and research institution have developed the various magneto products that can satisfy different actual demands in succession; but in existing magneto product; its application surface is narrow; and shortage safeguard measure; therefore as in use breaking down, will bring the loss that is difficult to retrieve to manufacturer.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of wide application, can protect the safe motor of motor operation, good energy-conserving effect.
The technical solution of the utility model is: a kind of safe motor; comprise protecgulum, middle cover, bonnet, rotor and stator; it is characterized in that: described middle cover is fixedly connected with bonnet with protecgulum respectively; bonnet boring, middle cover are the tubular of hollow, are provided with thermal protector outside middle cover; the middle cover inboard is provided with stator; rotor comprises rotating shaft, rotor core and permanent magnet, and described rotating shaft is arranged in rotor core by bearing, is inlaying permanent magnet outside rotor core.
Described permanent magnet is rubidium iron boron magnet ring.
The beneficial effects of the utility model are:
1. designed the bonnet that boring can be used for mounting circuit boards, the parts such as encoder can be installed according to actual needs, put forward high-revolving control precision, thereby better meet practical application request;
2. installed thermal protector additional, the temperature by the induction machine surface plays the protective effect to motor, avoids that motor breaks down under the environment such as low temperature, thereby makes troubles for people's work and life;
3. permanent magnet is rubidium iron boron magnet ring, and rubidium iron boron magnet ring belongs to the terres rares magnet ring, has advantages of that coercive force is high, anti-degaussing ability is strong, and is more superior than ferrite performance, can greatly improve electric efficiency, and energy-saving effect is better.
Description of drawings
Fig. 1 is the structural representation of safe motor described in the utility model.
In figure, 1-protecgulum, 2-middle cover, 3-bonnet, 4-rotor, 5-stator, 21-thermal protector, 22-terminal box, 41-rotating shaft, 42-permanent magnet.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
as shown in Figure 1, a kind of safe motor, 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, bonnet 3 borings, bonnet 3 outsides are provided with terminal box 22, the parts such as encoder can be installed according to actual needs, rotating speed with accurate control rotor 4, better meet the demand of practical application, middle cover 2 is the tubular of hollow, middle cover 2 outsides are provided with thermal protector 21 and terminal box 22, thermal protector 21 can induction machine the temperature on surface, prevent motor operation and breaking down under low temperature or overheated state, middle cover 2 inboards are provided with stator 5, rotor 4 comprises rotating shaft 41, rotor core and permanent magnet 42, rotating shaft 41 is arranged in rotor core by bearing, permanent magnet 42 is being inlayed in the rotor core outside, in the present embodiment, permanent magnet 42 is rubidium iron boron magnet ring, what rubidium iron boron magnet ring adopted is rare earth permanent-magnetic material, has coercive force high, the strong advantage of anti-degaussing ability, more superior than ferrite bead performance, can greatly improve electric efficiency.Therefore, the utility model can be applicable to different occasions, and fail safe is good, and is more energy-conservation than common electric machine, 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.
Claims (2)
