Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of novel tangential magnet-steel hybrid exciting synchronous motor.
Background technology
Magneto has outstanding advantages: without excitation loss, efficiency is high, adopts rotor permanent magnet structure can realize non-brushing.But excitation field is difficult to regulate become and limits it at bottleneck high-power and high reliability applications and popularization.Hybrid exciting synchronous motor adds electric excitation to control winding to realize the effective adjusting to air-gap field on magneto basis, causes the extensive concern of Chinese scholars as a kind of New-type electric machine.The air-gap field of rotor Splittable HESM is that the circumferential component stack by permanent magnet flux and electro-magnetic flux obtains, and therefore when the optimum Working of motor, the permanent magnetic potential of generator is substantially equal with electric excitation magnetic potential effect, and power of motor density is lower.And air gap flux density and no-load electromotive force on the low side, inherent voltage regulation is higher, the exciting current while making motor nominal load is larger, efficiency is not high, is difficult to be applied to large-power occasions.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of efficiency height and the adjustable novel tangential magnet-steel hybrid exciting synchronous motor of excitation are provided.
The utility model technical scheme adopting of dealing with problems is: novel tangential magnet-steel hybrid exciting synchronous motor, comprise stator and rotor, also comprise casing, annular magnetic bridge a, excitation winding, armature winding, armature core, rotor S utmost point pole shoe, permanent magnet, rotor N utmost point pole shoe, rotating shaft, annular magnetic bridge b, rotor N utmost point pole shoe and rotor S utmost point pole shoe extend axially in opposite direction and form rotating pole-piece structure, stator cage is provided with annular magnetic bridge a and annular magnetic bridge b, the upper embedding of annular magnetic bridge a and annular magnetic bridge b is around excitation winding, described stator comprises armature core and the upper and lower two-layer armature winding embedding in armature core groove, described rotor comprises rotor N utmost point pole shoe, rotor S utmost point pole shoe and tangential magnetization permanent magnet.
The beneficial effects of the utility model are: the utlity model has efficiency height and the adjustable advantage of excitation, tangential-set magnet permanent synchronization motor rotor structure is " poly-magnetic " effect, has the remarkable advantage that air gap flux density is high, is specially adapted to high-power applications occasion.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides a kind of novel tangential magnet-steel hybrid exciting synchronous motor, comprise stator and rotor, also comprise casing 1, annular magnetic bridge a2, excitation winding 3, armature winding 4, armature core 5, rotor S utmost point pole shoe 6, permanent magnet 7, rotor N utmost point pole shoe 8, rotating shaft 9, annular magnetic bridge b12, rotor N utmost point pole shoe 8 and rotor S utmost point pole shoe 6 extend axially in opposite direction and form rotating pole-piece structure, casing 1 is provided with annular magnetic bridge a2 and annular magnetic bridge b12, the upper embedding of annular magnetic bridge a2 and annular magnetic bridge b12 is around excitation winding 3, described stator comprises armature core 5 and the upper and lower two-layer armature winding 4 embedding in armature core 5 grooves, described rotor comprises rotor N utmost point pole shoe 8, rotor S utmost point pole shoe 6 and tangential magnetization permanent magnet 7.
Different from traditional magneto, in the utility model, both there is radial flux path, there is again axial magnetic flux path, radial flux is through main air gap, and linkage armature winding 4 is effective air gap magnetic flux.Axial magnetic flux path is as shown in phantom in Figure 1: the S utmost point of the N utmost point → rotor N utmost point pole shoe 8 → the first additional air gaps 10 → annular magnetic bridge a2 → magnetic conduction casing 1 → annular magnetic bridge b12 → the second additional air gap 11 → rotor S utmost point pole shoe 6 → permanent magnet 7 of permanent magnet 7.
Visible, during excitation winding 3 excitation-free current in magnetic conduction bridge, the magnetic field under main pole is in weak magnetic state.Can by adjusting main gas length and additional air gap length and main pole axial length and excitation pole axial length, regulate the degree of weak magnetic, reduce the possibility that permanent magnet is demagnetized.In excitation winding 3, pass into exciting current, excitation magnetic potential has hindered the magnetic flux of additional air gap magnetic circuit, and main air-gap flux is increased, and plays the effect that main air-gap field is increased to magnetic.
The utlity model has efficiency height and the adjustable advantage of excitation, tangential-set magnet permanent synchronization motor rotor structure is " poly-magnetic " effect, has the remarkable advantage that air gap flux density is high, is specially adapted to high-power applications occasion.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection range of the claims in the present invention.
