Stator tooth 11ta shown in Fig. 8 (B) forms the shape corresponding with the rotor tooth 12ta shown in Fig. 8 (A) (roughly L word shape).Rotor tooth 12tb shown in stator tooth 11tb shown in Fig. 8 (C) and Fig. 8 (A) forms accordingly along the symmetric shape of Zhou Fangxiang symmetry.Stator tooth 11tc shown in Fig. 8 (D) forms the shape as the enantiotropy that becomes stator tooth 11ta.Consist of according to this, in specific position or the zone before and after it, magnetic flux is easily by flange shape position due to rotor 12, and this magnetic flux increases the magnetic resistance magnetic flux, so can improve the torque of electric rotating machine 10.In addition, owing to observing from rotor 12 integral body, magnetic flux distribution is inhomogeneous, so the magnetic resistance magnetic flux increases in magnetic flux distribution high zone, revolving force (rotating torques) improves, and increases at the rotating speed of the low regional rotor 12 of magnetic flux distribution.
In addition, for the ease of understanding, figure 8 illustrates the shape of 3 kinds, but in fact be not limited to 3 kinds.That is, be set as the species number of the best at the flange shape position that magnetic flux easily forms by each leading section at stator tooth 11t and rotor tooth 12t.Although also depend on the quantity of formed tooth, can be 2 kinds, also can be 4 kinds, can also be for 5 more than kind.In addition, according to the specification of electric rotating machine 10, require characteristic etc., also have tooth group Tg1(stator tooth 11ta) with tooth group Tg3(stator tooth 11tc) be configured in opposite position, situation about forming with the shape of mirror image with Fig. 8 (A).
In addition, the shape of stator tooth 11ta～11tc is not limited to the shape shown in Fig. 8 (B)～Fig. 8 (D).For example, can be also the shape shown in Fig. 7 (C), can also be the shape shown in Fig. 7 (D), can also be other shape.In a word, for the magnetic resistance magnetic flux increases, just magnetic flux easily gets final product by the shape at flange shape position.
With reference to Fig. 9, in above-mentioned such dynamo-electric machine system that consists of 1, the example of controlling the running of electric rotating machine 10 describes.Fig. 9 with flowcharting an example of step that control to process of running.This running is controlled and processed is one of control processing by control device 20 execution, is repeated to carry out.Wherein, in Fig. 9, step S11 is equivalent to magnetic flux control part 21 and winding switching part SW, and step S14, S17 are equivalent to exciting current control part 22.
Control in processing in running shown in Figure 9, at first differentiate whether received any signal (step S10) from external device (ED).This signal comprises above-mentioned rate signal, operation mode signal etc.If receive any signal (no) from external device (ED), do not carry out any action, return to running and control processing.On the other hand, when receiving any signal from external device (ED) (being), carry out the later processing of step S11 described later.
In addition, as shown in parantheses, also can differentiate and whether satisfy for the controlled condition of carrying out the control relevant to the running of electric rotating machine 10.Controlled condition can be according to the specification of electric rotating machine 10, require characteristic etc. to set condition arbitrarily.For example, above-mentioned from external device (ED) receive any signal, the detected value etc. that utilizes the detected detected value of detecting sensor to reach regulation that carries out before the execution of step S10 meets.
In step S11, based on rate signal and the operation mode signal the signal that receives from external device (ED), the magnetic flux that produces in rotor 12 is controlled.Specifically as described above, control the stator current Is flow through stator winding 11a size, flow through the size of the exciting current Ir of excitation winding 12a.Because the size of stator current Is, exciting current Ir changes because of this control, so in step S14 described later, stator current Is is differentiated.In addition, because excitation winding 12a is connected to heterogeneously, so transmit switching command Sc to winding switching part SW shown in Figure 2, carry out mutually the switching of excitation winding 12a by each.
With the control of above-mentioned steps S11 together, utilize detecting sensor to detect the state (step S12) of electric rotating machine 10.For the detected object that detects with detecting sensor, such as comprising more than of current values such as magnitude of voltage, exciting current Ir or stator current Is such as rotating speed, temperature, induced electromotive force (regenerated energy) or phase voltage etc.Utilizing the detected detected value of detecting sensor in the recording medium that is recorded in control device 20 and possesses, also as required as shown in double dot dash line to external device (ED) transmission (output) (step S13).This transmission for example externally device need to be grasped inferior the carrying out of situation of the state of current electric rotating machine 10.
Whether differentiation detected stator current Is in step S11 is (step S14) more than the rated current value.The rated current value as described above for example for vehicle, be for obtain when the starting, when acceleration, the required torque of philosophy and the current value that flows through etc. when climbing is travelled.If stator current Is does not return to running with less than rated current value (no), not carrying out any action and controls processing.
On the other hand, when stator current Is is rated current value when above (being), obtain the exciting current Ir(step S15 corresponding with the amount of the magnetic resistance magnetic flux that is produced by stator current Is).The method of asking for exciting current Ir is arbitrarily.For example, can be with reference to mapping graph that is pre-stored within recording medium etc., perhaps use the functional expression of the relation of material (meaning that comprises material, material) the regulation stator current Is of the magnetic that adopts according to stator core 11b, rotor core 12b and exciting current Ir to calculate.
Will be in step S12 detected exciting current Ir(detects the exciting current value) calculate the exciting current value with the exciting current Ir(that asks in step S15) compare, whether differentiate is to detect the exciting current value〉calculate exciting current value (step S16).If detect exciting current value≤calculating exciting current value (no), do not return to running with not carrying out any processing and control processing.On the other hand, when detecting the exciting current value〉when calculating the exciting current value (being), after having suppressed to flow through the exciting current Ir of excitation winding 12a (step S17), returning to running and controlling and process.
