Description

本発明は、電動車両の動力装置としての使用に適したインホイールモータに係り、より詳しくは、漏れ磁束による干渉を防止して効率を高めたインホイールモータに関する。   The present invention relates to an in-wheel motor suitable for use as a power device for an electric vehicle, and more particularly to an in-wheel motor that has improved efficiency by preventing interference due to leakage magnetic flux.

近年、電動車両の駆動動力装置として、車軸にブラケットを介して円環状のステータを取り付け、ホイール側にロータを固定したアウタロータ型のインホイールモータが検討されている。
インホイールモータは、一般に、ロータとして永久磁石を周方向に配設し、ステータとしてティースに巻線を巻いたコイルを有している。ステータのコイルに通電してロータを回転させると、ロータに固定されているホイールが回転する。そのホイールは、車軸にベアリングで回転自在に取り付けられているので、インホイールモータによって車輪が直接に回転駆動させられる（例えば、特許文献１参照）。 In recent years, an outer rotor type in-wheel motor in which an annular stator is attached to an axle via a bracket and a rotor is fixed to the wheel side has been studied as a drive power device for an electric vehicle.
In-wheel motors generally have a coil in which permanent magnets are arranged in the circumferential direction as a rotor, and windings are wound around teeth as a stator. When the stator coil is energized to rotate the rotor, the wheel fixed to the rotor rotates. Since the wheel is rotatably attached to the axle by a bearing, the wheel is directly driven to rotate by an in-wheel motor (see, for example, Patent Document 1).

インホイールモータは、ロータが外側にあるので、モータサイズが同じであるインナーロータ型のモータに比べ、ロータ外形を大きくできるので高トルクが得られるというメリットがある反面、電源電圧に制限のある電気自動車においては、一次巻線の巻数を大きくできないので、要求出力を得るためには電流値を大きくせざるを得ず、電流値をある程度制限した状態では高速回転と大出力化との両立が困難であるという問題点があった。   The in-wheel motor has an advantage that the outer shape of the rotor can be increased compared to the inner rotor type motor with the same motor size because the rotor is on the outside. In automobiles, the number of turns of the primary winding cannot be increased, so the current value must be increased to obtain the required output, and it is difficult to achieve both high-speed rotation and high output when the current value is limited to some extent. There was a problem that.

低速高トルク、高速回転特性の両立を図るために、特性の相異なる複数のロータを共通回転軸上に直列配置し、複数の電動機体部の各々を選択的に制御して、共通回転軸を回転駆動する電動機が提案されている（例えば、特許文献２参照）。   In order to achieve both low-speed high-torque and high-speed rotation characteristics, a plurality of rotors having different characteristics are arranged in series on a common rotation shaft, and each of the plurality of electric motor body parts is selectively controlled so that the common rotation shaft is An electric motor that rotates is proposed (see, for example, Patent Document 2).

しかしながら、上記のような、共通回転軸上に特性の異なる２個のロータを直列配置し、対応する２個のステータを有する構造のモータは、２個のステータ相互の漏洩磁束の干渉が起こり、期待した特性が得られないばかりでなく、火災等の危険もはらむものであった。
このような問題に対し、２個のステータ間に絶縁体を介在させて漏洩磁束の干渉を防止しようとする試みがなされているが（例えば、特許文献３参照）、特許文献３に記載されたような方法では、磁束の漏洩を十分に遮断することができず、漏洩磁束の干渉が起こり、十分な特性が得られないという問題点があった。 However, in the motor having the structure in which two rotors having different characteristics are arranged in series on the common rotating shaft as described above and having two corresponding stators, interference of leakage flux between the two stators occurs. Not only were the expected properties not obtained, but there was also a risk of fire and the like.
For such problems, attempts have been made to prevent interference of leakage magnetic flux by interposing an insulator between two stators (see, for example, Patent Document 3). Such a method has a problem that magnetic flux leakage cannot be sufficiently blocked, leakage magnetic flux interference occurs, and sufficient characteristics cannot be obtained.

図１、２において、１はインホイールモータであり、図１はインホイールモータの軸線方向に直行する断面図であり、図２は軸線方向に平行な断面図である。
本発明の好ましい実施形態に係るインホイールモータ１は、低速高トルク用の第１巻線１５を備えた第１ステータ部１４と、第１ステータ部１４の外周に微少の隙間をあけて回転自在に配設され、低速高トルク用の第１永久磁石２３を有する第１ロータ部２２からなる第１モータ部と、第１ステータ部１４と間隔をあけて直列配置され、高速回転用の第２巻線１７を備えた第２ステータ部１６と、第２ステータ部１６の外周に微少の隙間をあけて回転自在に配設され、高速回転用の第２永久磁石２５を有する第２ロータ部２４からなる第２モータ部と、モータ軸５とから構成されている。 1 and 2, reference numeral 1 denotes an in-wheel motor, FIG. 1 is a cross-sectional view orthogonal to the axial direction of the in-wheel motor, and FIG. 2 is a cross-sectional view parallel to the axial direction.

Are arranged in series with a first motor part composed of a first rotor part 22 having a first permanent magnet 23 for low speed and high torque, and a first stator part 14, and are arranged in series with a second for high speed rotation. A second stator section 16 having a winding 17 and a second rotor section 24 that is rotatably disposed with a slight gap around the outer periphery of the second stator section 16 and has a second permanent magnet 25 for high-speed rotation. And a motor shaft 5.

第１ステータ部１４と第２ステータ部１６は、ステータコア上に、それぞれ複数のティース１２を設けた構成であり、各ティース１２には絶縁物１３を介して巻線が集中巻きで巻かれている。
第１ロータ部２２と第２ロータ部２４は、ロータコア２１の内周部に、それぞれ複数の希土類磁石やフェライト磁石などの永久磁石を週方向に設けた構成となっている。 The first stator portion 14 and the second stator portion 16 are each configured by providing a plurality of teeth 12 on a stator core, and windings are concentratedly wound around each tooth 12 via an insulator 13. .

The form of the 1st magnetic flux partition plate 30 is plate shape, and the thickness should just be about 0.5-5 mm normally, Preferably it is about 1-3 mm.

第１磁束隔壁板３０の材質は、炭化ケイ素、カオリニウムを主たる成分とし、白金、チタン、クロム、ロジウム、アンチモンから選ばれる少なくとも１種の金属を含む材料である。
第１磁束隔壁板３０の成形は、炭化ケイ素、カオリニウムを主たる成分とし、白金、チタン、クロム、ロジウム、アンチモンから選ばれる少なくとも１種の金属を含む材料を焼成することによって行ってもよく、バインダーとなるポリマー材料を加えて板状に成形してもよい。 The material of the first magnetic flux partition plate 30 is a material containing silicon carbide and kaolinium as main components and containing at least one metal selected from platinum, titanium, chromium, rhodium, and antimony.

第２磁束隔壁板３２及び第３磁束隔壁板３４は、第１磁束隔壁板３０とロータコア２１との微少な間隙を塞ぐように、第１磁束隔壁板３０を挟んでロータコア２１に設けられ、形状は円環状である。
第２磁束隔壁板３２及び第３磁束隔壁板３４の機能は、第１磁束隔壁板３０とロータコア２１との微少な間隙を塞ぐことにより、漏れ磁束の遮断を完全なものとし、インホイールモータ１の運転中の第１磁束隔壁板３０の倒壊を防止する役目を果たす。
第２磁束隔壁板３２及び第３磁束隔壁板３４の材質は、第１磁束隔壁板３０と同様に、炭化ケイ素、カオリニウムを主たる成分とし、白金、チタン、クロム、ロジウム、アンチモンから選ばれる少なくとも１種の金属を含む材料である。 The second magnetic flux partition plate 32 and the third magnetic flux partition plate 34 are provided in the rotor core 21 with the first magnetic flux partition plate 30 interposed therebetween so as to close a minute gap between the first magnetic flux partition plate 30 and the rotor core 21.

Further, the effect of preventing the interference of magnetic flux is further enhanced by making the gap between the first magnetic flux partition plate and the rotating rotor core small.

Since it can be completely prevented, the efficiency of the motor is remarkably increased, and the low speed and high torque characteristics and the high speed rotation characteristics are compatible without increasing the size of the motor, making it an optimum power device for an electric vehicle.
