Abstract
Description
本発明の第2の態様によると、インバータ装置は、搬送波と信号波とに基づくPWM制御によるインバータ印加電圧を、6線3相モータに印加するインバータ装置であって、前記信号波は、前記搬送波の振幅よりも大きな振幅を有する基本波と3次高調波信号とを含み、振幅が前記搬送波の振幅以下である。
本発明の第3の態様によると、モータシステムは、6線3相モータと、搬送波と信号波とに基づくPWM制御によるインバータ印加電圧を前記6線3相モータに印加するインバータ装置と、を備えるモータシステムであって、前記信号波は、前記搬送波の振幅よりも大きな振幅を有する基本波と3次高調波信号とを含み、振幅が前記搬送波の振幅以下である。
−第1の実施の形態−
図1は、6線3相モータを駆動するためのモータシステム1の概略構成を示す図である。モータシステム1は、インバータ装置200、インバータ装置200により駆動されるモータ100を備えている。なお、直流電源201については、モータシステム1に含める構成でも良いし、含めない構成であっても良い。
本実施の形態は、毎極毎相のスロット数が2以上の場合にも適用することができる。図11は毎極毎相スロット数が2の場合の図であって、本実施の形態を適用しない場合を示す。U相の相帯122は、電気角180ピッチで配置されている。V相およびW相の相帯も、U相の場合と同様である。相帯122の配置は図8の(U+)および(U−)の場合と同じ配置であり、図8の場合と同様の理由で、磁束密度分布の3次高調波成分に起因する3次高調波誘起電圧が発生する。
歪み波電流を流した場合も同じ次数の成分が含まれ、同一次数の成分の大きさもほぼ同一になっていることが分かる。
上述した第1の実施の形態では、ステータ構造を図9,10,18のような構成とすることで3次高調波誘起電圧E3をE3=0とし、E3とモータに流れる3次高調波電流I3とに起因するトルクリップルの発生を防止するようにした。一方、第2の実施の形態では、ロータ側の構造を工夫することで、3次高調波誘起電圧E3を低減し、I3とE3とに起因するトルクリップルを抑制するようにした。
