3.异步速度不同：二级电动机2880转，四级电动机1450转，六级电动机960转 对于相同功率，不同极数的电机：磁极对数越多，转速越低，体积越大，但输出的扭矩大。磁极对数越少，转速越高，体积越小，但输出的扭矩也小。/iknow-pic.cdn.bcebos.com/5366d0160924ab182798f5ea3bfae6cd7a890b64"target="...
ab、cd、h分别为直角梯形abcd的上底、下底、高 ∵S梯形=﹙ab＋cd﹚h/2=96 ab=5 ab＋cd=2×ef=12→ cd=7 ∴h=16 ∴S阴影 =96－ab×﹙h/2﹚/2－cd×﹙h/2﹚/2 =96－﹙ab＋cd﹚h/4 =48 平方厘米
