Motor and electric system elaborate.
A kind of permanent magnet direct driving motor that at least one embodiment of the utility model provides, including：Magnetic shoe 100, protection ring
200, shaft 300 and adhered layer 400；
Magnetic shoe 100 is fixed on by adhered layer 400 on 300 outer wall of shaft；
The fixing groove 500 for fixing magnetic shoe 100 is provided on protection ring 200；
Protection ring 200 is set in the outside of shaft 300, and the end of magnetic shoe 100 is located in fixing groove 500, so that magnetic shoe
100 inner wall and four sides are respectively positioned in fixing groove 500.
It should be noted that being fixed on due to magnetic shoe 100 on the outer wall of shaft 300, when shaft 300 works, magnetic shoe is given
100 1 centrifugal force, therefore inevitably will appear the phenomenon that magnetic shoe 100 flies out to the direction far from shaft 300, in order to
Increase the stability of magnetic shoe 100, is then useful for the protection ring 200 of blocking magnetic shoe 100 in the end set of magnetic shoe 100, and be
The intensity for increasing protection, then be provided with fixing groove 500, so that the inner wall of magnetic shoe 100 and four sides in protection ring 200 here
Face is respectively positioned in fixing groove 500.In this way while magnetic shoe 100 is simply fixed on shaft 300, and more protect together
Barrier substantially increases safety and reduces the noise of motor.
Also, motor here is minor diameter shaft.
In addition, the number of protection ring 200 is two, and two protection rings 200 are separately positioned on the both ends of magnetic shoe 100.Tool
Body, protection ring 200 is symmetrically arranged in the end of magnetic shoe 100.
Since motor speed is excessively high, winged watt is prevented, a pair of of protection ring is made under the premise of not influencing performance and space
200, so that magnetic shoe 100 (patch 8-12 blocks magnetic shoe 100), in this way while magnetic shoe 100 is simply fixed on shaft 300, again
More one of protective barrier, substantially increase safety and reduce the noise of motor.
Here, the cross section of fixing groove 500 is c-type；
Magnetic shoe 100 is limited when shaft 300 rotates, magnetic shoe 100 is effectively prevent to fly out.
Fixing groove 500 is designed to c-type, is on the one hand that the planform of fitting magnetic shoe 100 is designed, on the other hand,
It is fixed on due to magnetic shoe 100 on the outer wall of shaft 300, when shaft 300 works, gives 100 1 centrifugal force of magnetic shoe, therefore not
Evitable to will appear the phenomenon that magnetic shoe 100 flies out to the direction far from shaft 300, the fixing groove 500 of c-type is to magnetic shoe 100
Centrifugal force plays effective counteracting.
In addition, permanent magnet direct driving motor includes：Stator 600；
Several timesharing windings 700 are wound on stator 600, and timesharing winding 700 is arranged at intervals on inside stator 600.
Here timesharing winding 700 has three-phase, respectively here to be configured in Fig. 4：A phases, B phases and C phases；Here
A phases, the spaced mode of B phases and C phases so that its formed magnetic direction as the scale of clock, therefore, here
Winding be defined as timesharing winding 700.
Using timesharing winding 700, the dosage of enameled wire is saved, cost is reduced.Under Same Efficieney compared with conventional motors, body
Product 1/5-1/7, efficiency improve 25%-55%.Compared with magneto, volume 1/5, efficiency improves 10%.
In addition, the number of magnetic shoe 100 is 8-12, and the circumferential direction of the outer wall along shaft 300 is distributed.
Here the number of magnetic shoe 100 can be 8,10,12, be not particularly limited, here magnetic shoe 100
The selection of number is mainly selected according to the use occasion of motor.
The rotor in permanent magnet direct driving motor that at least one embodiment of the utility model provides has magnetic circuit short, and magnetic effect is high,
Heat consumption is small, it is small the advantages that.
Specifically, magnetic shoe 100 is uniformly pasted onto on 300 outer wall of shaft.Magnetic shoe 100 is uniformly pasted onto in shaft 300,
So that the distribution of magnetic induction line is more uniform, to effectively raise the working efficiency of motor.
In order to enable magnetic shoe 100 is firmly pasted onto in shaft 300, the material of adhered layer 400 here is solidification glue.
It should be noted that permanent magnet direct driving motor includes：Controller；
Input voltage is converted to output DC voltage 310VDC by controller from alternating voltage 220VAC, to conveniently make
User uses.
The permanent magnet direct driving motor that at least one embodiment of the utility model provides eliminates brush, therefore most directly variation
The electric spark generated when exactly being operated without brush motor thus greatly reduces electric spark to remote-control radio electric equipment
Interference.
Also, frictional force greatly reduces when operating, and operation is smooth, and noise can be much lower, this advantage is for stable
Property is a huge support.
Brush is lacked, the abrasion of brushless motor is mainly on bearing, and from a mechanical point of view, brushless motor is almost one
The non-maintaining motor of kind when necessary, need to only do some dedustings maintenance.Upper next comparison, is known that brushless electricity
Machine relative to brush motor advantage where, but all things is not absolute, brush motor low speed torsion has excellent performance,
The performance characteristics such as torque is big are that brushless motor is irreplaceable, but with regard to the ease of use of brushless motor from the point of view of, with brushless
The cost downward trend of controller and the both at home and abroad development of brushless technology and market competition, the hair of brushless power system high speed
Exhibition and stage of popularization, this has also been greatly facilitated industrial expansion.
From using effect：
Brushless motor：Typically digital frequency conversion controls, and controllability is strong, from several turns per minute, all may be used to tens of thousands of turns per minute
To be easily achieved.
Carbon brush electric motor：Working speed is constant after old carbon brush electric motor generally starts, and speed governing is not easy to, series excited machine
20000 revs/min can be reached, but service life can be shorter.
From energy-saving square surface analysis：
In contrast, brushless motor is more energy saving than series excited machine much using the meeting of converter technique control, most typical to be exactly
Convertible frequency air-conditioner and refrigerator.
In terms of repair in the future, carbon brush electric motor needs replacing carbon brush, if replacing the damage that can cause motor not in time, and
Brushless motor, service life is very long, typically 10 of brush motor times or more, but is broken and just needs replacing motor, but daily
Maintenance does not need substantially.
In terms of noise with whether be that brush motor is unrelated, be primarily to see the mated condition of bearing and motor internal component.
Second aspect, at least one embodiment of the utility model provide a kind of electric system, including：First aspect is any
Permanent magnet direct driving motor described in.
It should be noted that electric system provided by the utility model has the advantages that all of above-mentioned permanent magnet direct driving motor,
And it is easy to use, it is safe.
The permanent magnet direct driving motor of the utility model and electric system are illustrated above, still, the utility model is not
It is defined in above-mentioned specific embodiment, without departing from the scope of the claims, various deformations or change can be carried out
More.The various modifications and change that the utility model is included within the scope of the claims.
Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it
System；Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should
Understand：It still can be with technical scheme described in the above embodiments is modified, either to which part or whole
Technical characteristic carries out equivalent replacement；And these modifications or replacements, this practicality that it does not separate the essence of the corresponding technical solution are new
The range of each embodiment technical solution of type.
