(1) ティースを有するステータコアと、前記ティースに巻回されたコイルと、を含むステータの製造方法であって、
アモルファス構造を含む板状の軟磁性材料が複数積層された、前記ティースを有する積層体を準備する工程と、
前記ティースに前記コイルを装着する工程と、
前記コイルを装着した後、前記積層体を前記軟磁性材料の結晶化温度以上に加熱する工程と、
を含む、ステータの製造方法。
(2) 前記コイルに高周波電流を流すことにより前記積層体を加熱する、(1)に記載のステータの製造方法。
(3) 前記軟磁性材料が、アモルファス系軟磁性材料、又はアモルファス構造を含むナノ結晶系軟磁性材料である、(1)又は(2)に記載のステータの製造方法。
(4) 前記軟磁性材料の結晶化度が0%以上90%以下である、(3)に記載のステータの製造方法。
本実施形態において、ステータコア前駆体として、アモルファス構造を含む板状の軟磁性材料(ステータコア用板材とも称す。)が複数積層された、ティースを有する積層体を準備する。図2は、複数のステータコア用板材1aが積層されて形成された積層体10aの概略斜視図を示す。積層体10aは、複数のステータコア用板材1aを軸線方向に積層して形成することができる。
結晶化度(%)=([JA]−[JB])/[JA]×100 式(1)
式(1)中、JAは、測定対象である軟磁性材料に相当するアモルファス系軟磁性材料の結晶化発熱量であり、JBは、測定対象である軟磁性材料の結晶化発熱量である。
次に、積層体のティースにコイルを装着する。
コイルを装着した後、積層体を軟磁性材料の結晶化温度以上に加熱する。積層体を軟磁性材料の結晶化温度以上に加熱することにより、結晶化を促進させ、飽和磁化を向上させることができる。結晶化の促進には、結晶の生成及び結晶の成長が含まれる。また、この加熱により、プレス加工時の加工歪を除去することもできる。
アモルファス板(厚さ:25μm、結晶化温度:391℃、結晶化度:0%、引張強さ:1861MN/m2)を用意し、このアモルファス板をプレス型で打ち抜き、ステータコア用板材を作製した。なお、使用したステータコア用板材はアモルファス系軟磁性材料であるため、結晶化度は0%である。なお、結晶化温度は、示差走査熱量計(DSC)を用い、加熱速度0.67Ks−1の条件下にて発熱反応開始温度を測定することにより同定した。
ナノ結晶板(厚さ:25μm、結晶化度:90%、引張強さ:1820MN/m2)を用意し、このナノ結晶板をステータコア用板材にプレス型で打ち抜いた。
ナノ結晶板(厚さ:25μm、結晶化度:100%、引張強さ:1530MN/m2)を用意し、このナノ結晶板をステータコア用板材にプレス型で打ち抜いた。
