Traditional low speed and high-speed permanent magnetic generator is three-phase generation winding i.e. three-phase star and Y connection, is connect above
Method there was only two groups of generating windings acting i.e. numerical value equal direction when cutting magnetic induction line is done in rotor rotation on the contrary, another set then not
Power generation (being powered two-by-two) is to greatly reduce generated output.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides permanent magnet generator stator structure, with
The generating efficiency and generating voltage of permanent magnet generator are provided.
Technical solution: to achieve the above object, technical scheme is as follows:
Permanent magnet generator stator structure, including stator core and the two-phase being mounted on the stator core power generation around
Group；The stator core includes 2N wire casing, and N is positive integer；The two-phase generating winding include 2N be wound on respectively it is adjacent
Coil between two wire casings, the preceding N-1 coil of coiling is to enter line from the slot that is at the front, in rear wire casing since the 1st wire casing
Outlet, N coil enter line, the outlet of N wire casing and wire jumper from N wire casing and rewind to N+1 wire casing simultaneously around to N+2 wire casing, again
Wraparound N+2 wire casing enters line, in rear wire casing outlet from the slot that is at the front around N+1 coil, rear N-1 coil is produced.
Further, N=9.
Further, the coil turn of all coils is equal.
The utility model has the advantages that permanent magnet generator stator structure of the invention has the advantages that
(1) permanent magnet generator generating efficiency and generated energy are improved；
(2) symmetrical generating winding keeps the rotation of its rotor balanced smooth；
(3) symmetrical generating winding greatly reduces its rotor rotary resistance；
(4) structure operation simply easy to produce.
Detailed description of the invention
Attached drawing 1 is the developed winding diagram of two-phase generating winding.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
Permanent magnet generator stator structure, including stator core and the two-phase being mounted on the stator core power generation around
Group；The stator core includes 2N wire casing, and N is positive integer；The two-phase generating winding include 2N be wound on respectively it is adjacent
Coil between two wire casings, i.e. 2N coil be wound on respectively between the 1st wire casing and the 2nd wire casing, the 2nd wire casing and the 3rd wire casing
Between ..., between 2N-1 wire casing and 2N wire casing, between 2N wire casing and the 1st wire casing, the coiling since the 1st wire casing
Preceding N-1 coil is to enter line from the slot that is at the front, in rear wire casing outlet, and N coil enters line, the outlet of N wire casing simultaneously from N wire casing
Wire jumper is rewound around to N+2 wire casing, again to N+1 wire casing and wraparound N+2 wire casing is around producing N+1 coil, rear N-1 coil
Enter line, in rear wire casing outlet from the slot that is at the front.In order to guarantee that each coil generation torque is equal in magnitude, the circle of above-mentioned all coils
Number is equal.
Below by taking the stator core with 18 wire casings as an example, thereon around to there is 18 coils, as shown in Fig. 1 for 18
The developed winding diagram of the two-phase generating winding of a coil, as shown, the 1st coil is since the 1st wire casing in the 1st wire casing and
Coiling between 2 wire casings, from the 2nd wire casing outlet after the completion of coiling；Then using the 1st coil from the outlet of the 2nd wire casing as the 2nd coil
The 2nd coil of carry out coiling, the 2nd coil between the 2nd wire casing and the 3rd wire casing coiling and from the 3rd wire casing outlet ... with this
Analogize, until completing the 8th coil；9th coil enters line from the 9th wire casing, then lays out from the 9th wire casing and wire jumper is to the 11st slot, and
From the 11st slot reversely around to the 10th slot, further around returning the 11st slot, reciprocal coiling is around producing the so between the 10th slot and the 11st slot
11 coils；12nd coil to the 18th coil continues the coiling rule of the 1st coil to the 8th coil until around complete 18th coil, and the 18th
Coil enters line from the 18th wire casing, from the 1st wire casing outlet.
In above-mentioned 18 coils, the two whole structures respectively of the 1st coil to the 9th coil and the 10th coil to the 18th coil
At two symmetrical generating windings of two-phase generating winding, when winding scheme coiling, has distinguished the electric current side of two generating windings
To the positive and negative anodes for the voltage that two-phase generating winding generates are distinguished, symmetrical generating winding is met and does work equal side
To opposite requirement.Simultaneously as two generating windings also significantly reduce the resistance of magnetic gap bring the reason of symmetrically acting
Power keeps the rotation of its rotor balanced smooth.
The advantages of technical solution of the present invention, embodies as follows:
(1) permanent magnet generator generating efficiency and generated energy are improved；
(2) symmetrical generating winding keeps the rotation of its rotor balanced smooth；
(3) symmetrical generating winding greatly reduces its rotor rotary resistance；
(4) structure operation simply easy to produce.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
