Abstract
The invention provides an axial magnetic-flux dual salient pole generator. A stator and a rotor are salient pole structures; the number of the magnetic pole pair of the stator is two times of that of the rotor; a stator yoke sheet which is formed by circumferential piling of strip-shaped silicon steel sheets is fixed on a shell; the side surface of the stator yoke sheet facing to the rotor is provided with an armature winding which is wound by leads in the circumferential direction; two sides of the armature winding with polarity staggered are arranged in a magnetic tile with magnetism filled along the radial direction on the stator yoke sheet; a salient pole rotor is formed by the piling and embedding of the strip-shaped silicon sheets along the circumferential direction. The stator yoke sheet, the armature winding, the magnetic tile and the salient pole rotor assemble a unit motor; the multi-phase motor is formed by the serial connection of all unit motors coaxially; each phase motor is not provided with magnetic passage coupling independently. The magnetic tile (3), the salient pole rotor (1), the stator yoke sheet (2) and the air clearance form a magnetic passage and surrounds the armature winding (4); an alternative magnetic field is formed by the rotation of the salient pole rotor (1) to cut the armature winding (4), thus outputting the alternating current.
Description
Technical field:
The invention belongs to electrical generator fields, particularly a kind of axial magnetic flux double-salient-pole generator.
Background technology:
Present known generator is the rotor-exciting formula, but because the limitation of rotor space structure, that gives magnet steel fixedly causes very large difficulty, can't further improve the rotating speed or the linear velocity of generator therefrom, also more magnetic pole can't be installed, when adopting electric excitation, rotor need use slip ring and carbon brush, this cause the generator lost of life or safeguard inconvenience and reliability not high.
Summary of the invention:
The objective of the invention is to solve existing generator rotor structure than complicated problems, proposed a kind of axial magnetic flux double-salient-pole generator, simplify rotor structure, simplified manufacturing technique improves generator performance.
Technical solution of the present invention is: the axial magnetic flux double-salient-pole generator of the present invention's design, and each is independent mutually, does not have the magnetic circuit coupling, and it comprises stator and rotor two parts composition.It is characterized in that: stator and rotor are salient-pole structure; The magnetic pole of the stator number of pole-pairs is two times of rotor with salient pole number; Circumferentially pile up the stator yoke iron of forming and be fixed on the casing by the strip silicon steel sheet; Stator yoke iron is equipped with the armature winding of the circumferential coiling of lead towards the side of rotor; The magnetic shoe of the radial magnetizing of armature winding both sides polarity interlaced arrangement on stator yoke iron; Circumferentially pile up by the bar shaped silicon steel sheet and to inlay the field spider of forming.The above constitutes a unit motor, and polyphase machine promptly is composed in series by the unit motor coaxle, and each does not independently have the magnetic circuit coupling mutually.
Advantage of the present invention is that the silicon steel sheet that stator and rotor adopt all is bar shaped, has improved the utilance of material greatly; Stator is magnet steel and rotor is the silicon steel sheet of axial magnetic conduction fixedly, and this has fixedly reduced difficulty for magnet steel, and the reliability of rotor is improved during high rotating speed; When adopting electric excitation to substitute permanent magnetism, generator need not carbon brush, and designs simplification reduces cost.

Embodiment:
In Fig. 1, Fig. 2, the stator yoke iron (2) that circumferentially piles up by the bar shaped silicon steel sheet, by the armature winding (4) of the circumferential coiling of insulated conductor and polarity interlaced arrangement in the armature winding both sides and be fixed on radially magnetic shoe (3) above the stator yoke iron (2) and constitute stator jointly and be installed in the casing, circumferentially pile up the field spider (1) that is set into by the bar shaped silicon steel sheet and be installed in the casing by bearing and stator are coaxial.Magnetic shoe (3), field spider (1), stator yoke iron (2) and air gap constitute magnetic circuit and surround armature winding (4), along with the rotation formation alternating magnetic fields cutting armature winding (4) of field spider (1), thus output AC.Using the present invention when making low-speed generator, can directly make stator yoke iron (2) and field spider (1) and need not to use silicon steel sheet, processing simpler with electrician's soft iron.
