Embodiment
Embodiment 1
A kind of generating set with mixed excitation device as shown in Figure 1, comprise housing 1, rotor 2 and stator 3, rotor 2 is provided with magnet 20 and power coil 21, magnet 20 on described rotor is all corresponding power coil 21 of alternately arranged single pole magnet 200 and two pole magnet 201, static single pole magnet 200 and two pole magnet 201.
Concrete, described stator 3 is provided with multiple consequent pole 30, multiple short magnetic pole 31 and multiple coil assembly 32; Described consequent pole 30 is arranged on the inner side of housing 1, and the spacing of some consequent poles 30 is identical; In the present embodiment, taking the quantity of consequent pole 30 for three. At this, these three consequent poles 30 are called specific consequent pole; Specific consequent pole 30 on average is arranged on inside housing 1, and any two consequent poles 30 in three consequent poles 30 are all 120 ° with the central point angle in the cross section of housing 1.
Described multiple short magnetic pole 31 is all fixed on the inner side of housing 1, on average is distributed between consequent pole 30, makes stator have the magnetic pole structure of a pole formula; In the present embodiment, the quantity of described short magnetic pole 31 is 69, and every 23 short magnetic poles 31 on average are arranged between two consequent poles 30; Described coil assembly 32 is setting corresponding to consequent pole 30 respectively, and between consequent pole 30 and short magnetic pole 31.
Between described any two adjacent short magnetic poles 31, it is provided with the first spacing 310, it is provided with the 2nd spacing 300, first spacing 310 between each consequent pole 30 and adjacent short magnetic pole 30 and is less than the 2nd spacing 300; By such setting, the quantity summation of consequent pole and short magnetic pole is 72, and first spacing be less than the 2nd electric saw, therefore the angle of the kernel of section point of two adjacent short magnetic poles and housing is 5 °, through test, when the coil assembly that consequent pole is corresponding is energized, the magnetic line of force that the coil assembly that consequent pole is corresponding produces can extend effectively, and its magnetic line of force distributes as shown in Figure 2. Due to the magnetic pole structure of pole formula between stator use, therefore, the setting of short magnetic pole can reduce the magnetoresistance effect of air between two consequent poles, and improves the magnetic force decay of stator, make magnetic line of force distribution more evenly intensive, namely effectively improve rotor and stator magnetic flux density and magnetic force.
Described consequent pole 30 can need according to magnetic force to add or reduce, and in another one embodiment of the present invention, this consequent pole 30 is set to 6, and any two consequent poles 30 are all 60 ° with the central point angle in the cross section of housing 1.
More specifically, on described rotor, the quantity summation of single pole magnet 200 and two pole magnet 201 equals the quantity summation of consequent pole 30 and short magnetic pole 31 on stator.
More specifically, described power coil 21 and coil assembly 32 are three-phase generation coil, three-phase generation coil often alternates spread configuration, comprise A phase power coil, B phase power coil and C phase power coil, power coil in every phase power coil is forward and reverse to be alternately connected in series, just referring to that all power coils are sequentially connected in series end to end to series connection power coil, oppositely series connection power coil refers to that adjacent two power coil head's tail tails are sequentially connected in series.
When rotor relative stator is moved, in A phase power coil, magnetic field is still N pole, and B phase then changes into N pole by S pole, and C phase is still then S pole. Such A phase iron core inducedmagnetic field will repel the N pole on adjacent magnetic pole, forms a two-way repulsive force, cancels out each other. B phase then changes into N pole because S pole goes out N pole, repels and attracts adjacent magnets and the rotation of rotor is formed resistance. C phase still keeps S pole, produces to attract and repulsive force to rotor magnetic pole, and drive rotor rotates. Between ABC three-phase generation coil, just create attraction and repulsive force that part is cancelled out each other like this, make last formation hinder the less with joint efforts of rotor turns.
More preferably, the length of described stator 3 is the 1/3 ~ 1/2 of rotor 2; By such setting, it is possible to reduce magnetoresistance effect further, improve the magnetic force decay of stator, then can improve energy consumption, promote outward current.
