Specific embodiment
In the following, using Detailed description of the invention mode for carrying out the present invention.Indicate that explanation applies implementation of the invention in Fig. 1
The double rotor type axial-gap permanent-magnet synchronous motor 100 of example 1 is (hereinafter, sometimes referred to as " motor 100 ".) signal knot
The axial longitudinal section view of structure.
Motor 100 is configured to, and 2 discoid rotors 30 will configure cyclization along the inner peripheral surface of shell 50 across air gap
Face is opposite each other for the mode that the stator 10 of shape clips.The disk center of rotor 30 and rotary shaft 40 are fixed, and the perforation of rotary shaft 40 is fixed
Son 10 center portion and configure, both ends are rotatably fixed via bearing 70 and supporting member 60.Hold supporting member 60 by close
It is nearby fixed like two open ends of the shell 50 of cylindrical shape composition.Additionally, this invention is not limited to this, can be applied to single-turn
The various forms such as minor, the form being made of multiple stators and multiple rotors.
Rotor 30 has permanent magnet 31 across yoke 32 on circular pedestal 33.Permanent magnet is by centered on rotary shaft
Multiple flat magnet of inner circumferential with generally fan-shaped shape are constituted, and are configured with the magnetic of opposed polarity in a rotational direction
Iron.In addition, in the present embodiment, commonly used ferrite lattice is as permanent magnet 31, but the present invention is not limited to this.Example
Such as, it is also possible to omit the structure of yoke 32.
Stator 10 is by 12 20 structures of iron core unit using axis of rotation A as center direction and along the configuration of the inner circumferential of shell 30
At.1 iron core unit 20 constitutes 1 slot.In addition, iron core unit 20 each other with the inner peripheral surface of shell 50 by it is resin moulded that
This is molded as one, and is fixed on stator.
Illustrate the construction of iron core unit using Fig. 2.(a) is the perspective view of iron core unit in Fig. 2, is (b) cross-sectional view.Iron core
Unit 20 has iron core (core) 21, bobbin winder bracket 22 and coil 23.Iron core 21 is to be had greatly by the end face opposite with 30 face of rotor
It causes trapezoidal (including sector and the shape similar with this.) shape cylinder constitute laminated iron core.Laminated iron core will be by that will contain
The plate (or including elongated strip, band-like) of magnetic material goes to shell inner peripheral surface and width with spin spindle central A
The plate become larger is laminated and obtains.In addition, iron core 21 is not limited to this, the either iron core that still cuts of dust core is equal
Can, it can be in T, H or I font there are also the section of rotary axis direction.In addition, as magnetic material, commonly used amorphous metal,
But it is not limited to the material.
Bobbin winder bracket 22 is the insulating element being made of resin etc., has canister portion and flange part, and canister portion has and iron core 21
The about consistent internal diameter of shape, flange part extend in the complete cycle of vertical direction defined long near two open ends of canister portion
Degree.Specific length need not be identical in entire flange, can be suitably set according to specification.In the present embodiment, it is located at rotary shaft to rotate
The part (part opposite with trapezoidal bevel edge) of the left and right in direction and positioned at the inner circumferential side of shell 50 part (under trapezoidal
The opposite part in bottom) it is several compared to the thickness surplus length for the coil 23 being wound into, realize the coil 23 with adjacent iron core unit
With the insulation of the inner peripheral surface of shell 50.In addition, long more several than its in the part that axis of rotation side upwardly extends.In addition, flange
It can be set as coil thickness structure below.
Coil 23 is between the circumferential lateral surface and two flange parts of canister portion.Coil 23 increases winding tension, with high spatial
Coefficient winding.In addition, in the present embodiment, round wires are applied to coil 23, but in prolonging the diagonal line of square line and iron core 21
Direction is stretched vertically to come that the present invention can also be applied in the case where use.
(b) indicates the radial cross-section of iron core unit in Fig. 2.Coil 23 is with the butt part in the face of the canister portion side of flange part
For winding start, it is wound using rule winding.In addition, coil 23 is wound as, to form the firstth area in two flange part sides
Coil of the mode in domain 231 wound on the outside of bobbin winder bracket 22,1 circle of every 1 layer the number of turns reduction.
Firstly, the coil 23 of first layer winds (23a) since the radicle of (top in figure) flange part, then wind
To the butt part of another flange part.The second layer is turned back winding with configuring the mode between the coil 23 of the second layer as far as possible.
In addition, the coil 23 for being wound to the second layer of (top in figure) flange part side that turns back in the winding of first layer to rise
Circle between the circle coiled coil 23b and coil 23c thereafter of the coil 23a of beginning is finally, going back to the winding of third layer.
Thereafter the 4th layer, layer 5, layer 6 respectively than adjacent layer the number of turns reduce 1 circle be wound.In its result such as Fig. 2 (b)
Shown, coil 23 forms the trapezoidal winding in angle θ between flange part.The coil 23 of end layer is wound to adjacent coiling
The foundation of frame flange part is directly wound.
Fig. 3 indicates on two bobbin winder brackets 22 continuously winding (even around) perspective view of coil 23.By two when winding
Bobbin winder bracket 22 is fixed on fixture, but not shown.At this point, with the notch 22a and the second bobbin winder bracket of the first bobbin winder bracket of notch section
The close mode of notch 22b two bobbin winder brackets are configured with being inclined towards each other centered on center of gravity.Bobbin winder bracket is fixed with fixture
Afterwards, two bobbin winder brackets are rotated in the take-up direction.Meanwhile move the nozzle for supporting coil in the horizontal direction, thus by coil
Wound on canister portion.
In this example, after so that nozzle is repeatedly back and forth formed trapezoidal winding in the canister portion of the first bobbin winder bracket, coil 23 is led to
Cross the notch 22b that notch section 22a leads to the second opposite bobbin winder bracket.To the second bobbin winder bracket also make bobbin winder bracket rotate to be formed it is trapezoidal around
Group.After winding, the coil 22 between bobbin winder bracket is removed as shown in Figure 4 from notch section, two bobbin winder brackets is rotated, so that jumper 231
Pass through the first area of the winding of the second bobbin winder bracket.Thus coiling direction D different continuous coils is completed.
In this way, can reduce by connecting jumper 231 from the innermost side to adjacent iron core unit (the second bobbin winder bracket)
The relaxation of connecting line, and a possibility that winding a possibility that deforming and being unable to ensure insulation performance can be reduced.
The direction for winding winding is opposite direction on the first bobbin winder bracket and the second bobbin winder bracket.Such as just from bobbin winder bracket
When top is observed, if coil 23 around counterclockwise on the first bobbin winder bracket, coil 23 even around the second bobbin winder bracket
Clockwise on coil.Certainly, the relationship of the first bobbin winder bracket and the second bobbin winder bracket also has no relations on the contrary.
More than, embodiment for carrying out the present invention is illustrated, but the present invention is not limited to this.Such as at this
In embodiment, but it is also possible to be single-turn subtype by taking the axial gap electric motor of double rotor type as an example.Alternatively, it is also possible to not be
Motor but generator.
