and you get a lot of torque but a low speed . スピードは出ませんが 強いトルクを得ます
this is low speed , low wind speed 風が弱い低速時に
as passenger cars were also aging , some old cars were warped by vibration even when they were running at such low speed . 客車の老朽化もひどく、古い車両ではこの低速ですら振動で室内全体が歪むという状態であった。
in the early stage of rice polishing , kongo roru with coarse grinding function spins at high speed to remove outer shell from brown rice , and in the later stage of polishing when rice decreases its size to the point where it may be broken due to the heat generated by friction , kongo roru with fine grinding function spins at low speed to grind slowly into the central white-core structure of sake-brewing rice . 精米作業の初期段階には、目の粗い方の金剛ロールを高速回転して玄米を除芽し、生じる摩擦熱により米が割れかねないほど小さくなる作業後期には、目の細かい方の金剛ロールを低速回転させて、米の中心部分である酒米構造へ向かってゆっくりと削りをかけていく。
