Characteristics of the plastic, its geometry and its distribution may be varied to adjust spinning inertia and resonant frequency of the armature.
可以改变塑 料的构造、其几何形状和其分布以便调节电枢的旋转惯量和谐振频 率。
At present power converters of DC driving system make power supply outputs a high-frequency pulsating current, which is from zero to the armature current. This large ripple damages batteries.
目前国内外电动车直流驱动功率变换器使储能电源输出电流从零到电机电枢电流高频脉动，不利于延长动力电池的使用寿命。
The phase and frequency between the system and generator must be small enough to ensure minor current in the armature winding of generator, avoiding the impact to the coupling shaft.
避免由于压差、频差和相角差太大，使的合闸时，发电机组电枢绕组电流过大，对发电机组联轴系统产生冲击。
