`3. Detailed Description of Embodiments
` [Industrial Applicability]
`The present invention relates to a method for
`manufacturing an armature for an internal-rotation
`type multipolar magnet generator, the armature
`including, inside its inner circumference, a plurality
`of magnetic pole cores projected radially.
`
`
` [Related Art]
`As a generally known internal-rotation type
`multipolar magnet generator, there has been the
`one including an outer circumference core, a
`plurality of magnetic pole cores that is integrated
`with an
`inner circumference of
`the outer
`circumference core and is projected radially, and
`generating coils wound to outer circumferences of
`the magnetic pole cores from the inside of the outer
`circumference core
`(for example, Japanese
`Examined Utility Model (Registration) Application
`Publication No. S50-5922).
`
`
` [Problem to be Solved]
`However, according to the above-described
`known technique, since the generating coils are
`wound to the outer circumferences of the magnetic
`pole cores
`from
`the
`inside of
`the outer
`circumference core, the winding of the generating
`coils is disturbed by the outer circumference core.
`Furthermore, a winding machine has a complex
`
`
`
`Unexamined Patent Publication No.S62-138031
`
`an
`e.g.,
`for,
` Moreover,
`configuration.
`external-rotation type multipolar magnet generator
`including an inner circumference core and a
`plurality of magnet pole portions that is disposed on
`an outer circumference of the inner circumference
`core and is projected radially, a winding machine is
`designed to wind, from the outside, generating coils
`to outer circumferences of the magnetic pole
`portions. Such a winding machine is not applicable
`to
`the above-described
`internal-rotation
`type
`multipolar magnet generator.
` Thus,
`for
`manufacturing of the multipolar magnet generator,
`which involves a wide-variety small-lot production
`and a lot of production fluctuations, a lot of
`equipment with a low operation ratio is necessary.
`This causes the problem of a cost increase.
`In view of this, an object of the present invention
`is to allow the winding machine for an armature for
`the external-rotation
`type multipolar magnetic
`generator to be applicable even to an armature for
`the
`internal-rotation
`type multipolar magnet
`generator.
`
`
` [Means for Solving the Problem]
`In order to attain the object, the present
`invention provides a method for manufacturing an
`armature for an internal-rotation type multipolar
`magnet generator, the method including arranging
`a plurality of magnetic pole cores in an outer
`circumference of a support member such that the
`plurality of magnetic pole cores is projected radially,
`winding generating coils to outer circumferences of
`the plurality of magnetic pole cores, and thereafter
`fixing the outer circumferences of the plurality of
`magnetic pole cores to an inner circumference side

`
`
`of an outer circumference core, which has a
`ring-shape.
`
`
` [Effects]
`With this, before the magnetic pole cores are
`assembled to the outer circumference core, the
`winding of the generating coils can be performed by
`a winding machine in a state where the magnetic
`pole cores are arranged similarly to those of the
`external-rotation type.
`
`
` [Embodiments]
`The following describes the present invention
`with reference to embodiments illustrated in the
`drawings. In Figs. 1 to 3, the reference numeral “1”
`indicates an outer circumference core including an
`attachment hole 1a and a plurality of wedge-shaped
`grooves 1b. The attachment hole 1a is designed to
`perform attachment
`to an engine case (not
`illustrated). The plurality of wedge-shaped grooves
`1b, provided in an inner circumference of the outer
`circumference core 1, is configured to be engaged
`with wedge-shaped projections 2b formed on outer
`circumference portions of a plurality of magnetic
`pole cores 2 that is projected radially. The outer
`circumference core 1 is constituted by stacking of
`laminated steel sheets, and
`is
`formed
`in a
`ring-shape. The reference numeral “2” indicates
`the magnetic pole cores each having a magnetic
`pole portion 2a, which is disposed in a winding
`portion and an inner surface portion separated from
`the outer circumference core 1 and which is
`opposed to a rotor (not illustrated). The reference
`numeral “3” indicates generator coils wound to the
`outer circumferences of the magnetic pole cores 2.
`
`
`
`Unexamined Patent Publication No.S62-138031
`
`The reference numeral “4” indicates an insulation
`material
`fixedly
`attached
`to
`the
`outer
`circumferences of the magnetic pole cores 2 so that
`the generating coils 3 and the magnetic pole cores
`2 are insulated from each other. A support member
`4a, which has a ring-shape and is designed to make
`the magnetic pole cores 2 continuous, is formed of
`a resin so as to be integrated with an inner
`circumference portion of the insulation material 4,
`the inner circumference portion being opposed to
`the rotor. Furthermore, the reference numeral “4b”
`indicates side plates that are projected and insulate
`only the coil portions in order to avoid winding
`collapse in an outer side of the generating coils 2.
`The side plates 4b are formed of a resin such that
`the side plates 4b are integrated with the insulation
`material 4.
`In the above configuration, the magnetic pole
`cores 2, which are separated from the outer
`circumference core 1, are formed of an insulation
`material (e.g., a nylon resin). In this case, as shown
`in Fig. 3, the magnetic pole cores 2 are arranged
`such that the magnetic pole cores 2 are projected
`outwardly and
`radially.
` Furthermore,
`inner
`circumference sides of the magnetic pole cores 2
`are made continuous by the ring-shaped support
`member 4a of the insulation material 4, so that the
`magnetic pole cores 2 are integrated together in
`advance. In this state, winding wires of the
`generating coils 3 are wound by a winding machine
`to the magnetic pole cores 2 from an outer
`circumference having an opening. After the
`winding, the wedge-shaped projections 2b of the
`magnetic pole cores 2, which have been made
`continuous, are simultaneously driven into the

`
`
`
`wedge-shaped grooves 1b of the ring-shaped outer
`circumference
`core
`1
`for
`engagement
`therebetween. Thus, an armature as those shown
`in Fig. 1 is given.
`Fig. 4 shows another embodiment of the present
`invention. In this embodiment, a support member
`4a of an insulation material 4 is formed of a resin
`linearly in advance, so that magnetic pole cores 2
`are made continuous. The magnetic pole cores 2
`are then segmented by thin-walled portions 4b of
`the continuous support member 4a into pieces
`whose number corresponds to a desired number of
`poles. The resin pieces, which are continuous for
`the necessary number of poles, are bent into a ring
`shape.
` Thereafter, generating coils 3 are
`consecutively wound around the magnetic pole
`cores 2 by a winding machine. Furthermore, after
`the winding, wedge-shaped projections 2b of the
`magnetic pole
`cores 2 are driven
`into
`wedge-shaped
`grooves
`1b
`of
`an
`outer
`circumference
`core
`1
`for
`engagement
`therebetween. Thus, an armature is given. Here,
`parts of the thin-walled portions 4b in the resin
`pieces, which are formed of a resin so as to be
`continuous, has a reduced thickness to facilitate the
`bending at the continued portions. Moreover, as
`necessary, the support member 4a may be cut off at
`all the thin-walled portions 4b at a final stage, so
`that the support member 4a is separated into
`pieces each including one respective magnetic pole
`core 2.
`Fig. 5 shows further another embodiment. In
`this embodiment, each magnetic pole core 2 has a
`magnetic pole portion 2a, which is a part of both
`end plates 5 and is opposed to a rotor. The
`
`
`
`Unexamined Patent Publication No.S62-138031
`
`magnetic pole portion 2a has a flange 5a formed to
`be projected in an axial direction and to be bent.
`In
`the above-described embodiment,
`the
`support member 4a is formed to be integrated with
`the insulation member 4. Alternatively, in addition
`to the insulation member 4, a support member
`(which may be made of a metal material) may be
`provided. Such a support member is configured to
`detachably support inner circumference ends of
`magnetic pole cores 2 in such a manner that the
`magnetic pole cores 2 are projected outwardly and
`radially. After generating coils 3 are wound around
`the magnetic pole cores, the magnetic pole cores 2
`are simultaneously assembled
`to an outer
`circumference core 1. Thereafter, the support
`member is separated from the magnetic pole cores
`2. In this manner, the support member may be
`consecutively used as a manufacturing device for
`an armature 4, in manufacturing of the armature.
`
`
` [Effects of the Invention]
`As described above, with the present invention,
`before magnetic pole cores are assembled to an
`outer circumference core, the winding of the
`generating coils can be performed by a winding
`machine in a state where the magnetic pole cores
`are arranged
`similarly
`to
`those of
`the
`external-rotation type. Thus, the winding of the
`generating coils is not disturbed by the outer
`circumference core. Therefore, with the present
`invention, a configuration of the winding machine
`can be simplified. In addition to this, with the
`present invention, a single winding machine is
`applicable
`to both
`the
`internal-rotation
`type
`multipolar magnet
`generator
`and
