小群の英語

電磁鋼板数枚からなる鉄心群の間に制振鋼板を配し、磁束の変動による磁励振動を吸収すると共に、鉄心を小群化とする事で鉄心の共振周波数をさらに高いものとして、外部への騒音低減を図る。例文帳に追加

A damping steel sheet is disposed among groups of iron cores consisting of several pieces of electromagnetic steel plates, magnetic excitation oscillation due to the fluctuation of flux is damped, and reduction in noise to the outside is expedited by making the iron cores a small group and making the resonance frequency of the iron cores to be further higher. - 特許庁
