The efficient power generator of present embodiment (hereinafter to be referred as " generator ") 10 is 3 cross streams generators.Generator 10 has rotor 12 and stator 14.Rotor 12 rotatably is disposed to devices spaced apart the interior week of stator 14.
In addition, in the present embodiment, each permanent magnet 18 is along the outer peripheral face that axially and respectively is disposed at rotor 12.But, being not limited to this formation, each permanent magnet 18 also can be embedded in respectively in the hole that is formed at rotor 12 to extending axially.In addition, in the present embodiment, although the situation that rotor 12 stacked electromagnetic steel plates are consisted of describes, be not limited to this formation, rotor 12 also can be for by the ferrocart core formed thereby.
In addition, in the present embodiment, although the situation that stator 14 stacked electromagnetic steel plates are consisted of describes, be not limited to this formation, stator 14 also can be for by the ferrocart core formed thereby.
Between the T-shaped tooth 22 that adjoins each other, form the wire casing (slot) 24 as groove shape space.By wire on one side is wound in T-shaped tooth 22 on one side by wire casing 24, thereby form stator coil 26(as shown in Figure 3).
In the generator 10 that consists of like this, by acting on the rotating magnetic field that rotation was produced of rotor 12 and the electromagnetic induction effect between the stator coil 26, bring out voltage and generation current is mobile at stator coil 26, thereby generate electricity.
Being characterized as of the generator 10 of present embodiment, stator coil 26 constitutes unequal phase configuration.Unequal phase configuration refers to such as the configuration of generating for the stator coil 26 of the electric power of asymmetric 3 cross streams, is the formation different from the described impartial phase configuration of prior art.Adopt the generator 10 of the unequal phase configuration of such stator coil 26, because than impartial phase configuration, can suppress the reaction for the rotor 12 of rotation, namely suppress the increase for the opposing torque of each permanent magnet 18, the rotating speed of rotor 12 is increased and the realization high output.Below, describe for the concrete formation of the unequal phase configuration of stator coil 26.
In Fig. 1, T-shaped tooth 22 for the stator coil 26 that is wound with the U phase, deasil sequentially indicate the address (address) till U1 to U8, similarly, for the T-shaped tooth 22 of the stator coil 26 that is wound with the V phase, indicate the address till V1 to V6, in addition, for the T-shaped tooth 22 of the stator coil 26 that is wound with the W phase, indicate the address till W1 to W5.In addition, in stator 14 as shown in Figure 1, there are 5 without the T-shaped tooth 22 of the address that indicates stator coil 26.
In the stator coil 26 of U phase, coil U1 to U6 and U7 to U8 separate the T-shaped tooth 22 of 2 phase parts and are wound in T-shaped tooth 22, coil U6 to U7 separate 3 mutually part T-shaped tooth 22 and be wound in T-shaped tooth 22, and coil U8 to U1 separate 1 mutually part T-shaped tooth 22 and be wound in T-shaped tooth 22.In the stator coil 26 of V phase, coil V1 to V2, V3 to V4 and V5 to V6 separate the T-shaped tooth 22 of 2 phase parts, coil V2 to V3 separation 5 is the T-shaped tooth 22 of part mutually, and coil V4 to V5 separation 6 is the T-shaped tooth 22 of part mutually, and then V6 to V1 separates the T-shaped tooth 22 of 1 phase part and is wound in respectively T-shaped tooth 22.In addition, in the stator coil 26 of W phase, coil W1 to W2 and W3 to W4 separation 2 be the T-shaped tooth 22 of part mutually, and coil W2 to W3 separates the T-shaped tooth 22 of 5 phase parts, coil W4 to W5 separation 6 is the T-shaped tooth 22 of part mutually, and then coil W5 to W1 separates the T-shaped tooth 22 of 4 phase parts and is wound in respectively T-shaped tooth 22.
In the generator of existing example, the stator coil of each phase separate 2 mutually part T-shaped tooth and be wound in T-shaped tooth, make each phase difference between mutually with 120 ° equably mode dispose.But in generator 10 of the present utility model, stator coil 26 is not such as the equalization that is respectively 120 ° above-mentionedly at each phase difference between mutually, but at least a portion disposes in unequal mode.By such formation, can realize the unequal phase configuration of stator coil 26.
In addition, as shown in Figure 1,19 quantity that are wound on the stator coil 26 of T-shaped tooth 22 are less than the quantity of 24 T-shaped teeth 22.Then, these stator coils 26 dispose in the unequal mode of phase difference between each phase.Even by such formation, also can realize the unequal phase configuration of stator coil 26.Such unequal interval ground configuration stator coil 26 is at the structure of circumferencial direction, corresponding to unequal load configuration described later.At the utility model, also can give combination such as aforementioned unequal phase configuration with stator coil 26 and unequal load configuration.
In the present embodiment, although be that 19 situation describes to the quantity of stator coil 26, the quantity that the utility model does not limit this stator coil 26 is 19.Stator coil 26 also can be less than 19, also can be for whole T-shaped teeth 22 are reeled 24.More than any formation, all can be so that the unequal mode of phase difference between each phase will be arranged at the stator coil 26 and outlet side wiring of T-shaped tooth 22, perhaps with the stator coil 26 of part and the mode of not wiring of outlet side, realize the unequal phase configuration of stator coil 26.
Then, use Fig. 3 to describe for the output circuit of generator 10.The output circuit of generator 10 of the present utility model, as shown in Figure 3, the stator coil 26 that connects respectively each phase is U1, U2, U3 for example ... each lead-out terminal of U8 and the rectification circuit corresponding with these lead-out terminals 28, and at the outlet side of these rectification circuits 28, consist of in the mode of the output of the stator coil 26 of the homophase that is connected in parallel.By as output circuit, than the existing output circuit that connects respectively rectification circuit at 3 terminals of Y wiring or delta connection, can realize increasing the output current of each phase.On the other hand, in this output circuit, than existing output circuit, reduce the output voltage of each phase.But, by the unequal phase configuration of aforesaid stator coil 26, than conventional example, increase the rotating speed of rotor 12, therefore can realize the Towards Higher Voltage of each stator coil 26.Therefore, the formation according to generator 10 with its output circuit of present embodiment than existing example, can positively obtain high output, especially is of value to direct when output power is charged to the charger of secondary cell etc.In addition, in the time will charging to charger by the electric power of generator 10 generatings, connect respectively the lead-out terminal of each stator coil 26 and the rectifier 28 corresponding with lead-out terminal, and at these outlet sides, mode with the output of the stator coil 26 that is connected in parallel consists of, and namely constitutes good by the single-phase way of output.
In the present embodiment, the situation of interior rotary type generator that is disposed at the inboard of stator 14 for generator 10 for rotor 12 describes, but the utility model is not limited to this formations, also can be the outward rotation type generator of rotor configuration outside stator.
Then, use Fig. 4 to describe for the generator 30 of another execution mode.Fig. 4 shows the figure of formation of stator of the efficient power generator of another execution mode.In addition, the inscape identical with above-mentioned execution mode indicated identical symbol.In addition, formation and Fig. 2 of the rotor corresponding with the stator of this execution mode are same.
Being characterized as of the generator 30 of this execution mode, stator coil 26 constitutes unequal load configuration.Unequal load configuration refers to the reaction that produces for the permanent magnet that moves at circumferencial direction, i.e. the configuration of the stator coil 26 of the residual quantity of opposing torque is the formation different from the described impartial load configuration of prior art.Adopt the generator 30 of the unequal load configuration of such stator coil 26, because than impartial load configuration, can suppress the reaction for the rotor 12 of rotation, namely suppress the increase for the opposing torque of each permanent magnet 18, the rotating speed of rotor 12 is increased and the realization high output.Below, describe for the concrete formation of the unequal load configuration of stator coil 26.
The stator coil 26 of this execution mode is configured in the circumferencial direction of stator 14 in the mode of biasing.Refer to deflection in the zone of the regulation of circumferencial direction in the circumferencial direction biasing.As shown in Figure 4, T-shaped tooth 22 disposes 9 from the center-biased of power shaft 16 in the fan-shaped zone that is impaled by the angle (for example 120 °) of stipulating.Then, on each T-shaped tooth 22, reel respectively and be not shown in the stator coil 26 of Fig. 4.Like this, the zone of the regulation of stator coil 26 deflection circumferencial directions and disposing.In addition, the quantity of 9 T-shaped teeth 22 and stator coil 26 is an example, and the utility model is not limited to this quantity.In addition, in the present embodiment, although the situation to the T-shaped tooth 22 of biasingization formation describes, but the utility model is not limited to this formation, also can be at circumferencial direction uniformly-spaced to form T-shaped tooth 22, and be offset to mode in the circumferencial direction with stator coil 26, be wound on the part of these T-shaped teeth 22 and dispose.
Phase place at the stator coil 26 of this execution mode can at random be set.That is, can at each stator coil 26, by independence (single-phase) way of output that connects respectively output circuit, thereby take out output power.Perhaps, stator coil 26 equally spaced disposes in the tactic mode of U, V, W phase, and namely impartial phase place is disposed at circumferencial direction, also can connect respectively the 3 cross streams way of outputs of output circuit respectively communicating, thereby takes out output power.Perhaps, stator coil 26 in circumferencial direction with order differently U, V, the W mode of arranging mutually dispose, also can connect respectively the 3 cross streams way of outputs of output circuit respectively communicating, thereby take out output power.Owing at each stator coil 26 lead-out terminal is set, and the mode of connection that only changes this lead-out terminal just can at random set the phase place of stator coil 26, so promoted the design freedom of stator 14, and makes the adjustment of output power also become easy.
Like this, in this embodiment, T-shaped tooth 22, the stator coil 26 corresponding with T-shaped tooth 22 dispose in the mode of the circumferencial direction that is offset to stator 14.In the generator of existing example, the stator coil that equally spaced is configured in circumferencial direction is configured to the opposing torque stipulated for each mobile in a circumferential direction permanent magnet, i.e. offered load equally spaced.But in generator 30 of the present utility model, because stator coil 26 disposes in the mode that is offset to circumferencial direction, so the suffered load when circumferencial direction moves of each permanent magnet is not equalization, and becomes unequal.Like this, by the biasing at the stator coil 26 of circumferencial direction, can realize the unequal load configuration of stator coil 26.
In the present embodiment, although to the biasing by stator coil 26, the situation that consists of the unequal load configuration of stator coil 26 describes, and the utility model is not limited to this formation.As long as make in the load of circumferencial direction unequally, the wire diameter that also can constitute the stator coil 26 that is wound in certain T-shaped tooth 22 is different from the wire diameter of stator coil 26 that other is wound in T-shaped tooth 22.The coil number that in addition, also can constitute the stator coil 26 that is wound in certain T-shaped tooth 22 is different from the coil number of stator coil 26 that other is wound in T-shaped tooth 22.Perhaps, even with these formations that consists of combination, also can realize the unequal load configuration of stator coil 26.In addition, different from the magnetic force of other permanent magnet 18 by the magnetic force that constitutes certain permanent magnet 18 that is disposed at rotor 12, thus the suffered load when circumferencial direction moves of these permanent magnets is not equalization, that is, can form unequal yet.
Get back to Fig. 4, being characterized as of the stator 14 of this execution mode is the drum with power shaft 16 off-centre.Particularly, the center of the periphery of stator 14 and different from the center in concentric interior week of power shaft 16.The formation of such stator 14, particularly useful during the biasing of stator coil 26 in being implemented in circumferencial direction, realized the miniaturization of stator 14.Consist of by this, produce and make the diametrically large zone of length change of stator 14, in this zone, can guarantee the width of yoke 20, and form radially long wire casing 24 and T-shaped tooth 22.Wire casing 24 and T-shaped tooth 22 by such formation, than the identical existing stator of external diameter, at least one that can make the quantity of the wire that is wound in per 1 T-shaped tooth 22 or wire diameter becomes large, can realize the increase of the capacity of stator coil 26.In addition, along with the increase of wire diameter, reduce the quantity of coiling, for example just can obtain larger output current with 1.In addition, have in the situation of same outer diameter as in stator 14 and the conventional example of present embodiment, the wire with the employed length of stator coil that uniformly-spaced is disposed at circumferencial direction of conventional example all can be wound on the above-mentioned larger T-shaped tooth 22.
Then, use table 1 to the output characteristic of table 3 for the generator 30 of this execution mode describes.

The condition of bar is measured.This measured value is that the rotating speed of rotor 12 is that 785rpm, output voltage are that 2.2V, output current are 18A.Be 1 by making coiling, and at this coiling large electric current that flows, and increase wire diameter, can more increase output current.
In table 3, the condition of conventional example is that number of turns is that the quantity of 65T, stator coil is that 24, wire diameter are
Bar.That the rotating speed of rotor is that 428rpm, output voltage are that 0.37V, output current are 1.5A at the measured value of this condition.On the other hand, in the utility model, measure with the condition of changing into 9 of number of turns 56T, stator coil 26 quantity from the condition of conventional example.This measured value is that the rotating speed of rotor 12 is that 935rpm, output voltage are that 17V, output current are 17A.
Shown in these output characteristic, generator 30 can increase the rotating speed of rotor 12 than existing generator, and obtains high output.That is, constitute unequal load configuration by stator coil 26, thereby increase the rotating speed of rotor 12, and can reach high output.On the other hand, in generator 30, than existing example, owing to reduce the quantity of stator coil 26, therefore can reach the saving material.
In the present embodiment, the situation of interior rotary type generator that is disposed at the inboard of stator 14 for generator 30 for rotor 12 describes, but the utility model is not limited to this formations, also can be the outward rotation type generator 32 of rotor configuration outside stator.
