In addition, the side in female connector or male adapter can also be for example assemblied in the both ends of winding 141
141A, 141B, by the opposing party in female connector or male adapter located at the line inner peripheral surface for enclosing 150, with these female companies
Connecing device and male adapter carries out the line of armature coil 140.In such a situation it is preferred to female connector and male adapter are from rotation
The chimeric structure in the axial direction of rotating motor 1.So, by using female connector and male adapter, armature line can more simply be carried out
The line of circle 140.
Line circle 150 is integrally formed with motor casing (not shown), or embedded motor casing internal face and
Fixed.Thus, motor casing can be suppressed to maximize.
(magnetic flux distribution of stator)
Fig. 9 is the figure of the magnetic flux distribution for illustrating the stator 100 obtained by electromagnetic field parsing.In fig .9, for the ease of saying
It is bright and stator core 110 and rotor 200 are designated as linearly.In addition, in fig .9, the 1st stator tooth 131, the 2nd stator are not differentiated between
Tooth 132 or the 3rd stator tooth 133, are only meant as stator tooth 130.Additionally, Fig. 9 is illustrated is set to reference value by the current amplitude of V phases
1, the current amplitude value of U phases, W phases is set to into -0.5 and the analysis result in the case of being powered.
In fig .9, when the side in stator tooth 130 in the circumferential adjacent pair armature coil 140 is for V+ phases
When the opposing party is V- phases, the magnetic flux produced from a pair of armature coils 140 is towards the stator tooth clipped by a pair of armature coils 140
130, in stator tooth 130 occur to assemble.Then, the direction of the magnetic flux for being produced from stator tooth 130 is just changed into stator yoke 120
The direction of friendship, tends to rotor 200 from stator tooth 130.
Then, after rotor core described later 210 of the part for the magnetic flux of trend rotor 200 by rotor 200, tend to
The stator tooth 130 clipped by a pair of armature coils 140 of W+ phases and W-phase.In addition, the remainder for tending to 200 magnetic flux of rotor leads to
After crossing the rotor core described later 210 of rotor 200, tend to the stator clipped by a pair of armature coils 140 of U+ phases and U-phase
Tooth 130.
So, in the face relative with rotor 200 of stator tooth 130, the magnetic for constituting the magnetic flux produced by armature coil 140 is returned
Road.Stator tooth 130 and rotor 200 relative face is produced face by electric rotating machine 1.
Therefore, torque produce face it is more, more can effectively utilizes it is close to improve torque by the magnetic flux that armature coil 140 is produced
Degree.Torque density means the size of the torque of per unit volume.
Rotor 200 possesses two surface sides of the axial direction including electric rotating machine 1 and the torque in 3 faces of inner peripheral surface side produces face, carries
High torque density.So, torque generation face becomes many, thus, it is possible to making 1 miniaturization of electric rotating machine and producing high torque (HT), therefore can be special
It is not suitable as being equipped on the electric rotating machine of hybrid vehicle etc..
